You should have started from here: http://www.jboss.org/jbossas/downloads/ For 5.0.0.GA, you should get to here: http://sourceforge.net/project/showfiles.php?group_id=22866&package_i... The *.MD5 and *.SHA-256 files are hashes that you can use to verify the downloads. The jboss-5.0.0.GA.zip file is the binary for use with JDK 5. The jboss-5.0.0.GA-jdk6.zip file is the binary for use with JDK 6. The jboss-5.0.0.GA-src.tar.gz file is the source for the app server (not the full source, though, many other projects appear only as JAR files).
