This is not the best solution, as this webservice is already in use ... Can anyone tell me why i get this NullPointerException at org.jboss.ws.core.jaxws.JAXBSerializer.getClassesForContextCreation(JAXBSerializer.java:108) or why the result of Class[] registeredTypes = (Class[])serContext.getProperty(SerializationContextJAXWS.JAXB_CONTEXT_TYPES); is NULL ? Found the accoring class at http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/... http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/...
