Dec 01 » Network Clients » VPPPN

VPPPN stands for virtual peer to peer private networking, the project provides a VPN client using a custom protocol to be able to setup up a point to point dynamic virtual network. This differes from openvpn in that it does not need a central server to pass the network's traffic. A central server exists to allocate IP addresses and provide a point of contact for the clients but once connections are established these services are no longer needed. This means that a VPPN network is free (as in beer) since to set up a network you do not need to invest in an always on Internet server. The project is open source and GPL (free as in speach) and runs on Linux and Windows XP, support for other operating systems is planned. Once established a VPPPN network behaves in a similar way to a normal IP network. To the end user this means you can setup an office network and drag and drop files between computers in a secure manner over the internet.

Jul 12 » Network Servers » JPPF

JPPF enables applications with large processing power requirements to be run on any number of computers, in order to dramatically reduce their processing time. This is done by splitting an application into smaller parts that can be executed simultaneously on different machines. How it works There are 2 aspects to this: Dividing an application into smaller parts that can be executed independently and in parallel. JPPF provides facilities that make this effort a lot easier, faster and much less painful than without them. The result is a JPPF object called a \"job\", itself made of smaller independent parts called \"tasks\". A JPPF Grid is made of a server, to which any number of execution nodes are attached. A node is a JPPF software component that is generally installed and running on a separate machine. This is commonly called a master/slave architecture, where the work is distributed by the server (aka \"master\") to the nodes (aka \"slaves\"). In JPPF terms, a unit of work is called a \"job\", and its constituting \"tasks\" are distributed by the server among the nodes for parallel execution.

Jul 01 » Profilers » japex

Japex is a simple yet powerful tool to write Java-based micro-benchmarks. It started as a simple project over a year ago, primarily aimed at testing XML and Fast Infoset performance, but has evolved into a rather sophisticated framework with support for XML and HTML output as well as various types of charts for displaying the results. It is similar in spirit to JUnit in that if factors out most of the repetitive programming logic that is necessary to write micro-benchmarks. This logic includes loading and initializing multiple drivers, warming up the VM, forking multiple threads, timing the inner loop, etc. One of the key design goals for Japex was extensibility. Via the use of a simple model of input and output parameters, it is possible to write micro-benchmarks to test practically anything.

Apr 08 » Testing Tools » Maveryx

Maveryx is a FREE and OPEN SOURCE Test Automation Framework for functional and regression testing of Java applications. Maveryx eliminates the “GUI Map” dependency. Testers don't have to capture (often recapture) and maintain any GUI Map. GUI objects described in the scripts are identified and located directly at runtime during the test scripts execution. Avoiding GUI Maps testers have the possibility of starting automation early in the software lifecycle, long before the application is released for testing. GUI objects identification is performed by an “intelligent” Finder powered by a highly configurable set of searching algorithms. Maveryx supports also approximate matching to identify the GUI objects even in case of few or partial information given in the test scripts (this is typical when deriving test scripts from lacking or partial application’s specifications or in testing non-mature/early software). Maveryx is OS independent and works with the most used free and commercial IDE such as Eclipse, NetBeans, JUnit, IBM Rational Functional Tester, etc.

Logback is intended as a successor to the popular log4j project. It was designed by Ceki Gülcü, the founder of log4j. It builds upon experience gained in building industrial-strength logging systems going back as far as 1999. Logback's basic architecture is sufficiently generic so as to apply under different circumstances. At present time, logback is divided into three modules, logback-core, logback-classic and logback-access. The logback-core module lays the groundwork for the other two modules. The logback-classic module can be assimilated to a significantly improved version of log4j. Moreover, logback-classic natively implements the SLF4J API so that you can readily switch back and forth between logback and other logging systems such as log4j or java.util.logging (JUL). The logback-access module integrates with Servlet containers, such as Tomcat and Jetty, to provide HTTP-access log functionality. Note that you could easily build your own module on top of logback-core.

Jul 09 » Databases » jiql

jiql is a Java database for Cloud computing. The database is accessed via a jdbc client. The data is actually stored in a cloud-based data store, such as Google's BigTable. The fact is Google App Engine at present only supports python. Java programmers need not be excluded, as jiql provides a way to at least utilize Google's BigTable. By uploading the jiql python controller (jiql.py) to Google App Engine (GAE), the jiql.py acts as a gateway between the jiql database engine and Google's BigTable (GBT). So a Java application, using standard JDBC calls to the jiql JDBC client, is able to store critical data in GBT. As the DataStore sits in the cloud, you essentially have a solution for distributed database access. Thus, although you may not be able to host a JAVA program on GAE, you can still use the Data Store, which is probably the most important aspect of cloud-computing - that is scalability and high availability.

StoryTestIQ (a.k.a. 'STIQ') is a tool for creating \"Executable Requirements\" which have also been known as acceptance tests or functional tests. STIQ was developed based on two other open source acceptance testing tools, Selenium and FitNesse. This combination allowed STIQ to capture the web browser based testing facilities and elegant command language of Selenium along with the wiki-based editing and pluggable Fit fixture loading of FitNesse. When developing web applications it is helpful for the cross-functional team to have a definitive and executable view of the requirements for a specified iteration. STIQ may be used to record what the team's customer needs and get sign off before developing even a single line of code. Most of the test cases which are recorded will be failing. It is the responsibility of the team to implement the requirements in order to make the test cases pass. These practices are based in the tradition of Test-Driven Development. STIQ may also be used in traditional development teams to create acceptance and functional tests. They may be used to supplement the team's unit tests with a Test-Driven Development approach or even to automate existing manual test cases.

Oct 04 » Web Servers » AsyncWeb

AsyncWeb is a high-throughput, non blocking Java HTTP engine - designed throughout to support asynchronous request processing. AsyncWeb employs non-blocking selector driven IO at the transport level, and is asynchronous throughout - from the initial parsing of requests, right through to and including the services implemented by users. AsyncWeb breaks away from the blocking request / response architecture found in todays popular HTTP engines. This allows it to be highly scalable and capable of supporting very high throughput - even in high processing latency scenarios. A simple API allows new asynchronous services to be created easily - and out-of-the-box Spring integration allows them to be configured simply and with great flexibility. In addition to \"endpoint\" HTTP services, AsyncWeb also allows configurable \"chains\" of behavior - enabling \"filter\" like behavior to be applied to all requests. Pluggable \"resolvers\" map incoming requests to their target HTTP service - and are given access to the entire incoming request - allowing the routing possibilities to be very flexible.

Sep 14 » Testing Tools » Jumble

Jumble is a Java mutation testing tool that works in conjunction with JUnit. The purpose of mutation testing is to provide a measure of the effectiveness of test cases. A single mutation is performed on the code to be tested, the corresponding test cases are then executed. If the modified code fails the tests, then this increases confidence in the tests. Conversely, if the modified code passes the tests this indicates a testing deficiency.

Aug 31 » Testing Tools » T2

T2 is a random testing tool. As one, it is fully automatic, but one must keep in mind that the code coverage of random testing is in general very limited. It should be used as a complement to other testing methods. T2 checks for internal errors, run time exceptions, method specifications, and class invariant. T2 does not check individual methods in isolation; instead T2 generates random executions where methods may interfere with each other, and thus it may discover more subtle errors. Violating executions can be saved for re-test (regression). No special specification language is needed. Specifications are written in plain Java. The current state is prototype.

Aug 29 » Testing Tools » Dumbster

The Dumbster is a very simple fake SMTP server designed for unit and system testing applications that send email messages. It responds to all standard SMTP commands but does not deliver messages to the user. The messages are stored within the Dumbster for later extraction and verification. The Dumbster slots itself very easily into your testing strategy. As long as your application talks to an email server using SMTP then the Dumbster can be used to test the application with no code changes. The Dumbster is useful in the following scenarios: * System testing an application. It is important at this stage of the development process that all functionality is active and not stubbed out. The Dumbster is able to respond just like a regular SMTP server but delivers no email messages to end users. This is important if you are testing with real world data. In addition it is possible to verify that the correct email messages would have been delivered to the end users by querying the Dumbster. * Unit testing code that needs to send email. Again the Dumbster can be used as a dumpster to collect all email and ensure nothing is delivered to real users. In addition if the code being tested needs to deliver a specific set of email messages, with specific content then the Dumbster can be queried from within the unit test to verify correct delivery and content. The Dumbster is written in Java and is open source. It is distributed under the Apache License 2.0.

Nov 22 » Testing Tools » DDSteps

DDSteps is a JUnit extension for building data driven test cases. In a nutshell, DDSteps lets you parameterize your test cases, and run them more than once using different data. Since DDSteps is 100% JUnit compatible, you can run your new data driven test cases just like any old JUnit test case. No IDE plugins or new Ant tasks are required - just add the DDSteps jars to your classpath and you are ready to go! DDSteps uses external test data (in Excel) which is injected into your test case using standard JavaBeans properties. Your test case is run once for each row of data, so adding new tests is just a matter of adding a row of data in Excel. DDSteps integrates best-of-breed toolkits for web and database testing, such as JWebUnit, DbUnit and Spring Framework. By making these toolkits data driven, you can do powerful function testing. Automated end-to-end testing of your website is not only possible - it is easy. Features: * Run a JUnit TestCase method many times, each time with different test data. * Write tests in Java/JUnit and write data in Excel, using the best tool for each task. * Handles massive amounts of test data by keeping data separate from code, thus enabling both to be as compact as possible. * Use standard JavaBean getters/setters to fill your testcase with data. You don't have to write any code to pull in data, all that is handled by the DDSteps framework. * Tap into the power of property injection which is a complement to dependency injection found in frameworks like Spring. Property injection does not deal with dependencies, it handles simple data, but lots and lots of it.

SweetRules is a uniquely powerful integrated set of tools for semantic web rules and ontologies, revolving around the RuleML (Rule Markup/Modeling Language) emerging standard for semantic web rules, and supporting also the closely related SWRL (Semantic Web Rule Language), along with the OWL standard for semantic web ontologies, which in turn use XML and, optionally, RDF. (SWRL rules are essentially an expressive subset of RuleML rules.) SweetRules supports the powerful Situated Courteous Logic Programs extension of RuleML, including prioritized conflict handling and procedural attachments for actions and tests. SweetRules' capabilities include semantics-preserving translation and interoperability between a variety of rule and ontology languages (including XSB Prolog, Jess production rules, HP Jena-2, and IBM CommonRules), highly scaleable backward and forward inferencing, and merging of rulebases/ontologies. Procedural attachments can even be WSDL Web Services. SweetRules' pluggability and composition capabilities enable new components to be added relatively quickly. Implemented in Java, SweetRules has a compact codebase (~40K lines of code total for several dozen tools). The SweetRules project is an international, multi-institutional effort, originated and coordinated by the SweetRules group at MIT Sloan led by Benjamin Grosof, and its creation was funded largely by the DAML (DARPA Agent Markup Language) research program which co-pioneered the Semantic Web. SWEET (\"Semantic WEb Enabling Technology\") is an overall set of tools that Benjamin Grosof's group (with collaborators) has been developing since 2001. Other components in it include the SweetDeal e-contracting system approach and prototype, and the SweetPH system for business process ontologies drawn from the Process Handbook. Hundreds of users have already downloaded SweetRules, inspired in part by its well-received demonstrations in detailed presentations at the DAML Principal Investigators Meeting and the International Semantic Web Conference tutorial program.

Mule is a light-weight messaging framework. It is a highly distributable object broker that can seamlessly handle interactions with other applications using disparate technologies, transports and protocols. The Mule framework provides a highly scalable environment in which you can deploy your business components. Mule manages all the interactions between components transparently whether they exist in the same VM or over the internet and regardless of the underlying transport used. Mule was designed around the Enterprise Service Bus architecture, which stipulates that different components or applications communicate through a common messaging bus, usually implemented using Jms or some other messaging server. Mule goes a lot further by abstracting Jms and any other transport technology away from the business objects used to receive messages from the bus.

Jan 30 » Build Systems » Autojar

Autojar helps creating jar files of minimal size from different inputs like own classes, external archives etc. It starts from one or more given classes (e.g., an applet), recursively searches the bytecode for references to other classes, extracts these classes from the input archives, and copies them to the output. The resulting archive will only contain the classes that are really needed. Thus one can keep size and loading time of applets low or make applications independent of installed libraries. In a similar way, autojar can search directories and archives for other resources (like image files), extract them and copy them to the output. Although autojar can't know exactly which classes get loaded dynamically, it can search the bytecode for invocations of Class.forName() and warn about it. In some cases (constant class name), it can even find out which classes are to be loaded, and add them automatically to the output.

The PROSE system (PROSE stands for PROgrammable extenSions of sErvices) is a dynamic weaving tool (allows inserting and withdrawing aspects to and from running applications) PROSE aspects are regular JAVA objects that can be sent to and be received from computers on the network. Signatures can be used to guarantee their integrity. Once an aspect has been inserted in a JVM, any occurrence of the events of interest results in the execution of the corresponding aspect advice. If an aspect is withdrawn from the JVM, the aspect code is discarded and the corresponding interception(s) will no longer take place.

Jan 06 » NoSQL Databases » Berkeley DB Java Edition

Berkeley DB JE is a high performance, transactional storage engine written entirely in Java. Like the highly successful Berkeley DB product, Berkeley DB JE executes in the address space of the application, without the overhead of client/server communication. It stores data in the application's native format, so no runtime data translation is required. Berkeley DB JE supports full ACID transactions and recovery. It provides an easy-to-use interface, allowing programmers to store and retrieve information quickly, simply and reliably. Berkeley DB JE was designed from the ground up in Java. It takes full advantage of the Java environment. The Berkeley DB JE API provides a Java Collections-style interface, as well as a programmatic interface similar to the Berkeley DB API. The architecture of Berkeley DB JE supports high performance and concurrency for both read-intensive and write-intensive workloads. Berkeley DB JE is different from all other Java databases available today. Berkeley DB JE is not a relational engine built in Java. It is a Berkeley DB-style embedded store, with an interface designed for programmers, not DBAs. Berkeley DB JE's architecture employs a log-based, no-overwrite storage system, enabling high concurrency and speed while providing ACID transactions and record-level locking. Berkeley DB JE efficiently caches most commonly used data in memory, without exceeding application-specified limits. In this way Berkeley DB JE works with an application to use available JVM resources while providing access to very large data sets.

Oct 04 » General Purpose » TrueZIP

Although the ZIP file format it is a proprietary, de-facto standard by PKWARE Inc., ZIP files are ubiquitous on the Internet and thus on many platforms today. The J2SE API provides a well known package java.util.zip with classes like ZipInputStream, ZipOutputStream and ZipFile for easy access to ZIP compatible files. However, this package has some limitations/disadvantages: * Sun's implementation uses the character set UTF-8 (eight bit Unicode character set) for entry names and comments instead of CP437 (the genuine IBM-PC character set) as used by the de-facto standard PKZIP from PKWARE. As a result, you cannot read or write ZIP files with international entry file names such as \"t?cht.txt\" in a ZIP file created by a (southern) German. * You need to use an additional API (the package java.util.zip) if your application needs to support ZIP compatible files in addition to ordinary files and directories, thereby significantly inflating your code and adding unnecessary complexity (which adds bugs, bugs, and even more bugs). * You can either read or completely write ZIP compatible files, but you cannot just update individual entries. * The classes do not support the concept of a directory, which you may want to create, modify, list or delete. * You cannot browse a ZIP compatible file with a JFileChooser or FileSystemView. The TrueZIP Library has been developed to overcome these limitations/disadvantages.

O/R Broker is a convenience framework for applications that use JDBC. It allows you to externalize your SQL statements into individual files, for readability and easy manipulation, and it allows declarative mapping from tables to objects. Not just JavaBeans objects, but any arbitrary POJO. This is the strength of O/R Broker compared to other similar persistence tools. It allows the developer to design proper object-oriented classes for persistence, without having to be forced to use JavaBeans only, and it has full support for inheritance hierarchies and circular references. One of the design goal for O/R Broker was simplicity, which means that there are only 4 public classes, and an XML Schema file for validation of the very simple XML configuration file. In short, O/R Broker is a JDBC framework that does not dictate domain class design, whether that be having to conform to the JavaBeans spec, having to extend a superclass or implement an interface, but allows persistence independence and proper object-oriented class design.

JTR (Java Test Runner) is a framework meant for fastening the building of both complex and simple test enviroments. It is based on concepts such as Inversion of Control, and is ready for EJB and JMS testing. The JTR 2.0 framework will give you the chance to code only the testing logic. All the boring middleware-related tasks (connecting to ConnectionFactories, opening connections, sharing connections, opening sessions, handleing exceptions, retrieving administered objects) are carried out by the JTR 2.0 runtime on your behalf according to what you have stated in the jtr.xml configuration file. Thanks to IoC (Inversion Of Control), the JTR 2.0 runtime is able to inject all these resources into your IRunner concrete implementations. This entails that you are not required to actively retrieve the resources you need: you declaratively tell the JTR 2.0 framework you are going to need them at runtime, and Inversion Of Control will do the work. The thing same happens with EJBs: all the low-level details are always handled by the JTR framework to let you work only on the pure logic of your tests.

Apr 05 » General Purpose » Java Plugin Framework (JPF)

JPF provides a runtime engine that dynamically discovers and loads \"plug-ins\". A plug-in is a structured component that describes itself to JPF using a \"manifest\". JPF maintains a registry of available plug-ins and the functions they provide (via extension points and extensions). One major goal of JPF is that the application (and its end-user) should not pay any memory or performance penalty for plug-ins that are installed, but not used. Plug-ins are added to the registry at application start-up or while the application is running but they are not loaded until they are called.

Jan 31 » Inversion of Control » HiveMind

HiveMind is a services and configuration microkernel: Services: HiveMind services are POJOs (Plain Old Java Objects) that can be easily accessed and combined. Each service defines a Java interface it implements. HiveMind takes care of instantiating and configuring each service just as necessary. HiveMind lets services collaborate with each other via dependency injection. Configuration: HiveMind allows you to provide complex configuration data to your services in a format you define. HiveMind will integrate the contributions of such data from multiple modules and convert it all into data objects for you. HiveMind configurations allow for powerful, data-driven solutions which combine seemlessly with the service architecture. Microkernel: HiveMind is a framework for creating applications, not an application, or even an application server, itself. The 'core' of HiveMind is the startup logic that knows how to parse and understand the module deployment descriptors, and use that information to instantiate and initialize all those services and configurations. In HiveMind, a service is an implementation of a Java interface. Unlike other SOAs (Service Oriented Architectures, such as a SOAP, or EJBs), HiveMind is explicitly about combining Java code within a single JVM. HiveMind uses a descriptor to describe different services, their lifecycles, and how they are combined. HiveMind takes care of thread-safe, just-in-time creation of singleton service objects so your code doesn't have to.

Oct 18 » XML Parsers » XMLBeans

At a high level XMLBeans is an XML-Java binding tool that uses XML Schema as a basis for generating Java classes that you can use to easily access XML instance data in a natural manner in your Java programs. It was designed to provide both easy access to XML information via convenient Java classes as well as complete access to the underlying XML, combining the best of low-level APIs like SAX and DOM that provide full access with the convenience of Java binding. There are several factors that set XMLBeans apart from any other XML-Java binding alternatives: * XML Schema Compliance - XMLBeans has achieved extremely high schema compliance and is able to compile even the most complex schemas. This is critical when adopting an XML-Java binding framework since you may received schemas that are out of your control. * Access to the full underlying XML Infoset - The XML Cursor API allows you to access a lower level DOM like access to the underying XML Infoset. You can get a \"cursor\" at any point while using the strongly typed generated XMLBeans and begin navigating the underlying XML instance. * Access to the schema type system - The XMLBeans schema API allows you to walk through the schema type system giving you full access to a Java object representation of the XML Schema that was compiled to generate the XMLBeans classes. * Speed - XMLBeans is optimized for performance at many levels. For example, XMLBeans lazily constructs objects from XML, so that you do not have the performance overhead of object creation when you only access portions of an XML document. Several Fortune 500 customers have adopted XMLBeans based on speed alone.

Sep 06 » Testing Tools » Marathon

Marathon is a testing framework for GUI applications developed using Java/Swing. Marathon composes of recorder, runner and editor. The testscripts are composed of python code. Marathon focuses on end-user testing. One need not know Java or Swing to record test scripts using Marathon. Marthon is kept intentionally simple. The aim to produce test scripts that are readable by everyone on the project. This includes the developers, testers and the customers. Marathon is flexible and provides facilities to extend the functionality available through python scripts or through writing ones own component resolvers. Marathon captures the semantic actions on components instead of the mouse & keyboard events. This results in scripts that are simple and at a higher granular level. Marathon suites well for applications that mostly depend on forms-paradigm.

he goal of this project is to provide functionality roughly analogous to the portions of the C++ STL library that are not already provided by java. The primary functionality to be provided is: * a set of functors and predicates that may be applied both the the generic collections and to other areas of the standard java library. * basic utility algorithms for use with java collections such as those found in STL * implementations of standard java classes that are intended to be user-derivable that apply the algorithms and functors for general benefit (for example, implementations of standard swing models that take advantage of predicates and functors) We will not necessarily reproduce STL in all of its details: where Java and C++ provide different interpretations of standard design patterns, we will stay true to standard Java practices in order to be as comfortable for Java programmers to adopt as is practical. We will also not necessarily be limited by the scope or approach of STL

Here are some that Peapod handles: * hot-deploy and undeploy of JARs: just drop in a directory or remove a file to install or uninstall a component * intelligent dependency management: components are active only when all their declared dependencies have been satisfied--remove a component and all its dependents gracefully shut down; re-add it and they wake up * code versioning: declare you require version 1.0 and seamlessly receive a access to facilities provided by a 1.1 implementation--you can even have both versions running in the same container * combining the above three you get hot upgrades: undeploy a component, thus putting the dependents to sleep, deploy a newer version and not have to restart at all, enabling very high uptimes with a single lightweight server * external configuration by metadata * declarative aspect-oriented programming: use metadata to select code to insert at runtime between method calls made to an interface or even to a single method--tracing, security, transactions, single-threading, and more; the container includes several useful aspects you can use out of the box

The order can be defined through the visibility or by type (instance, class, constant). The same is applicable for methods. Each of those rules is highly customizable. Readability is enhanced by defining where to put white spaces in the code and when to use braces. The existence of correct JavaDoc can be enforced and various levels. Apart from that, it finds weaknesses in the the code -- potential bugs -- like empty catch/finally block, switch without default, throwing of type 'Exception', slow code, ...

Jun 08 » Workflow Engines » The Open for Business Workflow Engine

The Open for Business Workflow Engine is based on the WfMC and OMG spec; (See the related documents for information on these specs.) it is a member of the Services Framework, and is tightly integrated with the Entity Engine. It uses the entities found in entitymodel_workflow.XML for definition information and entitymode_workeffort for runtime storage. All changes to a process or activity are persisted real-time. Therefore, the engine does not run in a thread, it is simply a group of APIs and common objects which handle the flow. When a change to the workflow is made, the engine then processes that change. When finished, the engine returns. Hence, if the application does crash, or the system reboots, the workflow will continue right where it left off upon restart.

Jun 08 » Portals » MyPersonalizer

MyPersonalizer is a J2EE-based framework for engineering personalizable \"My\" portals. It is structured according to the Model-View-Controller (MVC) architectural pattern, providing generic and adaptable model and controller layers. The model layer represents persistent objects (e.g. user registration information, workspace layout, service personalization, etc.) in a generic way and makes use of meta-information about their structure, handles their persistence in a relational database, includes a framework to execute model actions and provides a generic action for each typical use case in the portal (sign in, sign up, service personalization, layout modification, etc.). The controller layer is built upon Jakarta Struts, the \"de facto\" MVC framework for J2EE web applications and provides a Struts action per use case, that delegates on the corresponding model action. In order to support the construction of the portal view, rather than providing a large and specific JSP tag library, controller actions are tightly integrated with Struts, so that the developer can implement the portal view as JSP pages by using Struts and JSTL tags, without inserting Java code. Personalized service replies are integrated in the portal by providing plug-ins as extensions to the controller layer.

The Slide project main module is a content repository, which can be seen as a low-level content management framework. Conceptually, it provides a hierarchical organization of binary content which can be stored into arbitrary, heterogenous, distributed data stores. In addition, Slide integrates security, locking, versioning, as well as many other services. It can integrate and manage data stored within external repositories, requiring only small abstraction layers to be written for each repository. That way, Slide can integrate the data from various physical locations in a hierachical and unified way. Slide uses can range from managing intranet application content to using it as a file server. Slide also offers a WebDAV access module (implemented as a servlet). WebDAV is an IETF standard endorsed by companies like Microsoft, IBM, Novell, Adobe and many others. It makes Slide an ideal choice for web-based content management. All the data managed by Slide can be accessed through WebDAV, and enable remote administration and manipulation of the data managed by Slide using standard third party tools, along with the custom ones provided in the Slide distribution as additional tools.

Like any caching system, the JCS is most useful for high read, low put applications. Dynamic content and reporting systems can benefit most. However, any site that repeatedly constructs pages, dropdowns, or common search results form a database that is updated at intervals (rather than across categories continuously) can improve performance and scalability by implementing caching. Latency times drop sharply and bottlenecks move away from the database in an effectively cached system.

ASM is a Java bytecode manipulation framework. It can be used to dynamically generate stub classes or other proxy classes, directly in binary form, or to dynamically modify classes at load time, i.e., just before they are loaded into the Java Virtual Machine. ASM offers similar functionalities as BCEL or SERP, but is much more smaller (25KB instead of 350KB for BCEL and 150KB for SERP) and faster than these tools (the overhead of a load time class transformation is of the order of 60% with ASM, 700% or more with BCEL, and 1100% or more with SERP). Indeed ASM was designed to be used in a dynamic way* and was therefore designed and implemented to be as small and as fast as possible. ASM can of course be used in a static way too.
