[jboss-user] [JBossWS] - jboss 4.0.2 Webservices dynamic proxy client issue : could

Fri Oct 26 10:26:25 EDT 2007

Hello,
I'm in a bit of a bind.
I'm working with webservices in jboss 4.0.2.
Trying a simple test at first.
I've successfully deployed a webservice.

However I have a problem when trying to access it using the a Dynamic Proxy Client. The problem
happens when I use a complex type.

I get the following exception:

java.rmi.RemoteException: null; nested exception is: 
	java.lang.reflect.UndeclaredThrowableException
