We're behind the following open source projects.

• Impala
  Impala is a new application development and runtime infrastructure which has the potential to revolutionise the way developers use the Spring Framework. Impala offers an rapid interactive development environment, modular plugins, and an infrastructure for dynamic redeployment and update of application components.
  
  
• Strecks
  A set of extensions to Struts which leverages Java 5 features to make Struts application development more productive. If you're stuck on Struts 1.x because your managers tell you so, but still want modern web framework features, you'll definitely want to check out this project.
  
  
• DataTest
  A small library which makes database application testing easier, particularly those using object relational mapping technologies. DataTest uses proxies to decorate JDBC operations, collecting information on SQL queries run, parameters passed in, etc. DataTest integrates with Spring and is particularly useful in testing Hibernate cacheing configurations.
  
  
• PerfTest
  PerfTest is a performance testing library which decorates JUnit and is well suited to load and stress testing and perfect for continuous integration. PerfTest solves a similar set of problems to JUnitPerf, but does so in a way that offers several advantages, which I hope to write about some time soon.
