I'm using JBoss 4 with Java 6u29. I generated some classes for a soap webservice with wsimport. Everything works fine except for one thing.
Whenever the webservice responds with a soap fault I get this exception:
java.lang.NoClassDefFoundError: Could not initialize class com.sun.xml.internal.ws.fault.SOAPFaultBuilder
The class is included in the JRE. I have no idea why this class isn't found. I searched on google but wasn't successfull. Do you have any idea what could cause this error?
