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?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p></blockquote><p>I don't think so, but I'd probably need to see more details / the code to better understand.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><blockquote class="jive-quote"><p>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.</p></blockquote><p>This looks like a problem with dependencies on a JAXB Impl module. Can you check what classloader is set as TCCL / is being used for resolution in JAXBContext.newInstance(..) when that's called by your handler? I guess a dependency on com.sun.xml.bind (with services=import) is missing somewhere.</p></div>
