An addendum :
The artifacts uploaded on the 10th had an issue with install onto jboss-as-6.0.0.Final and jboss-as-6.1.0.Final - there was a missing file (esb-juddi-orm-as6_1.xml). I've fixed this and reloaded the artifacts. If you saw this issue and it was preventing you from installing onto AS6, try downloading the current artifacts and re-try your install.
Sorry for any inconvenience this error may have caused.
