If you're using the 4.2MR2 release, this quickstart can only be run on 4.0.5GA of the JBoss AS. After that, follow the readme.txt.
The version on the SVN is out of commission at the moment, so don't bother trying that one. Sorry :-(
This quickstart is back working again - against the JBossWS v2.0.0 codebase. Be sure to read the readme.txt before trying out. Only runs on AS version 4.2.0GA.
