Xerces classloader problem?!

Hello,

I just tried to generate a war with the latest nightly build of soapUI 3.6.2 and I am not able to use this war in my application server, which is a JBoss 5.

I guess this issue is related to a classloader conflict between the endorsed xerces.jar of JBoss and the xerces.jar of the mocked service from SoapUI (see this post http://community.jboss.org/thread/65754 ... 0&tstart=0)
First when I tried to deploy the war I got deployment errors including OOME from JBoss
As I can not change the JBoss-Version I tried to delete the xerces.jar in the generated war --> due to that I was able to deploy the war
But if I try to run the mocked service I got a 500 internal server error
Also overwriting the xerces.jar in the endorsed directory of jboss with that one included in the generated war from soapUI let to no result

I am very annoyed.

The following error appears if I try to call the servlet:

Does anybody have a clue what additional poosibilities I have.

Best regards

PS.: however soapUI is a great piece of software, which helps a lot when dealing with SOAs. Thanks for that
