Hi, I got the same problem. My pure client code is much the same as the testcase of sample: jsr109ejb in jbossws-samples-1.0.3.GA, but I always get the NullPointException. However, if I run the testcase in the sample, it works fine!! I can't figure out what is missing in my pure client. Maybe the ServiceFactoryImpl will read some env properties when it try to create the service. My code like this: wsdlLocation = (new File("C:\\TestService.wsdl")).toURL(); QName serviceName = new QName(TARGET_NAMESPACE, "TestService"); ServiceImpl service = (ServiceImpl)factory.createService(wsdlLocation, serviceName, javaWsdlMappingFile.toURL()); ~~~~~~~~~~~~~~~~~~~~~ Here the exception comes out.
