Open Source Job Schedulers in Java
Quartz is an open source job scheduling system that can be integrated with, or used along side virtually any J2EE or J2SE application. Quartz can be used to create simple or complex schedules for executing tens, hundreds, or even tens-of-thousands of jobs; jobs whose tasks are defined as standard Java components or EJBs. |

This component provides a scheduler service. It is based on the TurbineScheduler provided with Turbine, but all older stuff has been removed. Currently ONLY the non persistent Scheduler is done. It loads scheduled jobs from the component config xml file. |

J2EE Scheduler is a simple task scheduling mechanism for J2EE applications. This library can be considered a wrapper around the Timer and TimerTask classes found in the standard Java API. Configuration for tasks to be executed and their frequency is XML-based. A typical use for it is to periodically refresh in-memory data to ensure it stays up-to-date. It can also be used for automated maintenance tasks or anything else that suits your need. |

Goal Oriented Scheduling for Java is a way of organising processing priorities based on goals. Each goal is processed based on its time to complete, and its progress towards that goal. Deadlines are used to act as the target completion time for a goal, and can be expressed in either relative or absolute terms. |

Oddjob is a free open source Java job scheduler and job tool kit.
Oddjob's goal is to provide some order and visibility to all the batch files and cron jobs that tie an enterprise's critical business processes together. Additionally Oddjob will often offer a more robust alternative to an existing process from it's toolkit. |

The Job Scheduler is a batch program operating as a demon, and can be controlled using a graphical user interface. The Job Scheduler uses an XML configuration for the scheduled programs, scripts and for the timing and frequency of task processing. An API is available for Java, Javascript, Perl, VBScript that hands control of events and logging to your jobs.
The Job Scheduler is used for Job Automation - for example, automatically running database procedures with the free database systems MySQL, PostgreSQL, with SQL Server or with Oracle.
The Job Scheduler is available for the following operating systems: Windows 2000 and Windows XP, Linux, Solaris and HP-UX. |

jBatchEngine is a batch job spooler written in Java.
In constrast to time driven schedulers like Cron, jBatchEngine is event driven. It uses a database table for job management and runs as a Windows Service or a Unix Daemon.
jBatchEngine can run any programm. There is also a facility for job monitoring. |

Super with SuperScheduler and SuperWatchdog is a Java job scheduler with rich GUI for all applications. It is platform neutral. Especially good to be a job scheduler for Linux and Solaris. It provides a super set of functionalities of the Scheduler of Microsoft Windows. It provides event-triggered scheduling. It can schedule tasks in a distributed environment. A task will be executed once and only once among all machines in the network. All tasks are holiday adjustable.
