I'm trying to set up a projekt with one Liferay portlet and two JAX-WS Web Services. The data transfer between the portlet and the service is over a SSL connection. I'm trying to get a Proxy Ticket in the portlet. In the web.xml of the service I already configuret the different CAS filter. Now when I try to call a web service I get a XMLStreamException. Here is the Stack Trace: Quellcode (22 Zeilen) Please, has anyone an idea, where the error is? If there are any question, I try to answer them!
