Open Source Logging Tools in Java

Houston is an open-source, light-weight status and logging toolkit offering a plug-in architecture to let you choose the underlying, industry-strength logging toolkit such as Apache log4j or Java 1.4's built-in java.util.logging toolkit. Houston uses the publish/subscribe model and sends reported errors, warnings, infos, hints, and so on to subscribed status handlers. Status handler for command-line apps usually display incoming messages in plain text on the console, while classic desktop apps display incoming messages in the status bar or in a message box using styled text in various colors (e.g red for errors, orange for warnings, etc) with icons and other visual gimmicks.
