I am new to JavaRanch. I just registered.
I have passed the SCJA few months back.
Now, I want to participate in a small open source project to get more practice.
I worked in the computing industry for a while, but my exposure to Java is limited.
I was thinking working on a Java - open source project will be good.
Is there someone that can recommend some of them ?
Welcome to the Ranch.
Check out http://www.java.net/projects/community or http://sourceforge.net/ or similar sites (google can help)
You can surf for projects which interest you. If the project leaders are open for collaborators, they usually have instructions on how to join.
Also, you can always start your own project
apache.org has many well-known open source Java projects, some of which you're bound to have used already (or are bound to use in the future). I generally advise to pick a project that you're interested in from a user's point of view; that makes it more likely that you'll stay interested in the long term IMO (and you should view getting involved with an open source project as a long-term thing, as it will take time to dig your teeth in).
