Open Source Technology Stack for Java Projects

Open-Source tools for Java development have reached a maturity that often goes far beyond commercial tools. A lot of Java projects doing business applications can come along with Open-Source tools. Here is a list of my current favorites.


  • Eclipsethe Open-Source IDE

  • CVSthe Open-Source revision control system

  • Antthe Java make

  • JUnitthe unit test tool for Java

  • Fitnesse – for acceptance tests

  • Jemmy [desktop frontends]- testing Swing UIs

  • HTTPUnit [web frontends] – testing Web UIs

  • JMeter [server side code] – for load tests of server side code

  • NoUnit – finding untested methods

  • Integration-Guard – server side test execution before/after checkin in CVS

  • DoxyGen – similar to JavaDoc but supports different output formats

  • PMD – identifies problems and smells in Java code

  • Eclipse Profiler Plugin – Profiler for Eclipse

  • XDoclet – generates data from Java meta tags; used for Hibernate, JBoss and others


  • log4j – for logging (more powerful and widespread than the logging facilities of JDK 1.4

  • Struts [web frontends] – framework for web applications

  • Eclipse Plugin Model [client side code] – the Eclipse plugin model can be used without the Eclipse IDE to implement a client side component model for Java

  • JFreeChart – generates business charts

  • JFreeReport, JasperReports – printing from Java


  • mySQL, PostgreSQL, SapDB – Databases

  • Hibernate – OR mapper with transparent persistence (requires XDoclet); if an existing database schema has to be used, Torque with its code generation approach may be more suitable


  • Apache Web Server – if a lot of static web pages exist or non-Java application logic has to be executed at the server

  • Jakarta Tomcat [web frontends] – if only a web interface is required

  • JBoss [server side code and desktop frontends] – if a desktop interface is required and server side code is neccessary (I recommend to use XDoclet to generate most of the EJB stuff)

  • MockEJB [server side code] – a local container for session beans; supports testing session beans and allows the execution of the system stand alone without an application server


  • XPlanner – Managing and planning of stories

  • JSPWiki – a simple Wiki web based on Java Server Pages

  • Open-Office – for external documents and project tracking


There are promising tools which I haven’t had the opportunity to use until now:
