The error message does not mean anything is wrong. It is just a trace of the wsdl fault (FaultInstance) wrapped by an exception (BpelFaultException). If the fault handler is not running, it is possible that the fault name or message type do not match the received fault. To determine what is going on, I'd need to see more of your log. Can you please make the server.log file (located in jboss-4.x/server/default/log) available online for me to examine? Alternatively, please post the messages that follow the stack trace.
