If you think you've found a problem with Geronimo, there are several ways to proceed.

You can begin by raising the issue on the Geronimo User mailing list (see Mailing Lists).

You can also search JIRA, our issue-tracking system, to see if the problem has already been noted (visit JIRA). If the issue is not listed there, you can add a new JIRA issue describing it. Please include detailed steps to reproduce the problem.

If you have a fix for the issue, you can generate a patch file to send the fix to us. You need to check out the current source code from Subversion (see Source Code), make the necessary changes, and then do a full build with all tests enabled and make sure the server still starts and runs as expected (try maven -o clean new to run a full build), and of course, confirm that the problem is actually fixed. Then, go to the base directory of your Geronimo checkout, and run a command like svn diff > fix-for-my-bug.patch to generate a patch file.

To submit a patch, create an issue in JIRA that describes the problem, and add your patch file as an attachment. Please include detailed steps to reproduce the problem in the issue description, and a test case in the patch where possible.

Thanks for working with us to improve Apache Geronimo!
