I will add the sources to the repository as well...
But as for now you could use https://svn.jboss.org/repos/messaging/projects/jms-integration
If you check out now... the head will be synchronize with the repository.
I didn't tag it because I screwed up when I created the project (not having it in the proper place.. I will probably have to move it somehow). I will fix it early next week (taging it and adding the source to the repo).
