Contributing to Java/J2EE open source projects

[Himanhsu Yadav]

I am a regular j2ee developer for one of the largest bank. Mostly worked on Struts 2, EJBs, MQs. Looking forward to contribute to open source to expand my java/j2ee programming skills and learn more. Can I get a list of java/j2ee open source projects?

I know this question may have asked many times but I want to find a project which matches my skills.

Did you check the list: java open source projects ?

What about joining the projects you already know, like Struts?
