From JBoss web site, when I clik on the download page of JBoss EJB3, I go on that page http://sourceforge.net/project/showfiles.php?group_id=22866&package_id=132063&release_id=346762

It only contains very old version (an alpha version of embedded ejb3). On that forum people speak about a beta 3 version.

Where can I find that release ?
