<div class="jive-rendered-content"><p>I had this error today, but on older JBoss (4.2.3). WSDL was a bit complex but not wrong (it was auto-generated from EJB, deployed on JBoss 5.1.0 - both wsimport and wsconsume were OK with it.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I'll describe how I have fixed it for myself. Maybe it will be helpful for anyone.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I had to create web service client and add to some application, deployed on 4.2.3. I've generated classes using wsimport and created the client. After that, I got the above mentioned error.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>As everyone knows, when you generate JAX-WS classes, wsimport uses absolute path of the filename in the ***Service.java. It looks like this:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span>@WebServiceClient(name = "MyService", targetNamespace = "</span><a class="jive-link-external-small" href="http://www.example.com/NS/my-NS" target="_blank">http://www.example.com/NS/my-NS</a><span>", wsdlLocation = "file:/D:/path/to/wsdl/Service.wsdl")</span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>and the same path exists after few lines, in static initialization block.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>When you deploy the application on the server, in most cases the pathname will be incorrect. To avoid this, I often place my .wsdl files in the package and create service class using MyService(URL wsdlLocation, QName serviceName) constructor but today it caused NPE for me. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I have tried to make above mentioned static initialization block and @WebServiceClient annotation little bit usable. Here are steps:</p><ol><li style="text-align: start;">Choose name of your package where wsimport will place generated classes. Say, com.mikheil.demo.ws.client</li><li style="text-align: start;">Put your WSDL in classpath, inside the SAME package. Let's suppose it's name is MyService.wsdl</li><li style="text-align: start;">When executing wsimport, pass<strong> -wsdllocation MyService.wsdl</strong> to it</li></ol><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I use Maven and plugin parameter there is wsdlLocation</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>So, here is how my service looks like:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span>@WebServiceClient(name = "MyService", targetNamespace = "</span><a class="jive-link-external-small" href="http://www.example.com/NS/my-NS" target="_blank">http://www.example.com/NS/my-NS</a><span>", wsdlLocation = "MyService.wsdl")</span></p><p>public class MyService</p><p>    extends Service</p><p>{</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>    private final static URL MYSERVICE_WSDL_LOCATION;</p><p>    private final static Logger logger = Logger.getLogger(com.mikheil.demo.ws.client.MyService.class.getName());</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>    static {</p><p>        URL url = null;</p><p>        try {</p><p>            URL baseUrl;</p><p>            baseUrl = com.mikheil.demo.ws.client.MyService.class.getResource(".");</p><p>            url = new URL(baseUrl, "MyService.wsdl");</p><p>        } catch (MalformedURLException e) {</p><p>            logger.warning("Failed to create URL for the wsdl Location: 'MyService.wsdl', retrying as a local file");</p><p>            logger.warning(e.getMessage());</p><p>        }</p><p>        URL MYSERVICE_WSDL_LOCATION; = url;</p><p>    }</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>// Some constructors, etc</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>}</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Obviously, now it's possible to create web service client using default constructor. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>...And, NullPointerException disappeared too!</p></div>
