As scott mentioned, you need to clarify your question a bit more. But if you are looking for the location of bundle jar files, Follow the steps below:
As jaideep mentioned all the jar files are under felix folder.
If you are looking for OOB jars present in http://localhost:4502/system/console/bundles then it will be available in .m2 folder.
Your question is not clear - what information are you looking for?
