I found another glitch in the XTS interop demo which is als a package problem but it was masked by not seeing an exception on the client side. The interop tests creates a JaxWS proxy for the test Participant service which drives XTS and then asks it to run a test. In some cases it passes transaction details using a handler to serialise them into the message. My handler was failing with an NPE but the client proxy did not receive any exception. Is this normal behaviour?
The NPE was because the handler failes to create a JaxB context - the call is JAXBContext.newInstance(pkgname); The call throws an exception whose detail message is "Provider com.sun.xml.internal.bind.v2.ContextFactory not found" I assume this is because of a service lookup problem. I'll see if I can work out thow to fix this.
