I'm developing a webservice with Axis2 1.4.1 on JBoss 4.2.3/Tomcat 5.5.27 and Java 1.5.0 (15-b04). It works flawlessly but when an exception happens I get a JBoss error 500 HTML page instead of an Axis2 XML/SOAP fault.

This behavoir is vexing, because it difficults to handle errors in the webservice client or in SoapUI while developing.

Can I change this to get the SOAP fault? Maybe it's just an Axis2 or JBoss parameter, but I didn't find any clue about.

EDIT: Here goes the new stacktrace:

EDIT 2: After giving the bounty I found that I was wrong about 1.2.9-SNAPSHOT version of Axiom. I built it again, made sure the jars where correctly copied to lib directory and it worked!

Finally, it was an Axiom bug, as said in the links provided by Vineet.

Thanks!
