Isssue in publishingWSDL for @WebServiceProvider

Question

I wrote an simple JAX-WS webservice for @WebServiceProvider. After deploying it as war while accessing the WSDL i am facing below error.
:/GPSProxy spec-version:2.5]] Servlet failed with Exception
java.lang.NullPointerException
at weblogic.wsee.jaxws.WLSServletAdapter.publishWSDL(WLSServletAdapter.java:239)
at weblogic.wsee.jaxws.WLSServletAdapter.handle(WLSServletAdapter.java:166)
at weblogic.wsee.jaxws.HttpServletAdapter.get(HttpServletAdapter.java:193)
at weblogic.wsee.jaxws.JAXWSServlet.doRequest(JAXWSServlet.java:93)
at weblogic.servlet.http.AbstractAsyncServlet.service(AbstractAsyncServlet.java:99
Why is it gives NullPointerException - - Can any one help us ..
WebService code looks like
package gpsproxy;
import java.io.ByteArrayOutputStream;
import javax.xml.ws.BindingType;
import javax.xml.ws.ServiceMode;
import javax.xml.ws.WebServiceProvider;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.Provider;
@WebServiceProvider(
portName="GPSProxyPort",
serviceName="GPSProxyService",
targetNamespace="http://services.mymclportal.com/SOA/GPSProxyService",
wsdlLocation="/WEB-INF/wsdl/GPSProxyService.wsdl"
@BindingType(value="http://schemas.xmlsoap.org/wsdl/soap/http")
@ServiceMode(value=javax.xml.ws.Service.Mode.MESSAGE)
public class GPSProxy implements Provider<SOAPMessage> {
public GPSProxy() { super(); }
public SOAPMessage invoke(SOAPMessage req){
System.out.println("Method invoked ");
System.out.println("invoke: Request: " + getSOAPMessageAsString(req));
return null;
private String getSOAPMessageAsString(SOAPMessage msg)
ByteArrayOutputStream baos = null;
String s = null;
try {
baos = new ByteArrayOutputStream();
msg.writeTo(baos);
s = baos.toString();
} catch(Exception e) {
e.printStackTrace();
return s;
And the web.xml is
<?xml version = '1.0' encoding = 'windows-1252'?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

Hi Kalyan,
I changed the version to 2.4 also did few changes...
Now , I am facing some weird issue. Able to see service address http://localhost:7001/GPSProxy-001/GPSProxyService .... But if i open WSDL in browser i get 404 error .... I am not getting any info... no exception in the logs also .....
WSDL ( http://localhost:7001/GPSProxy-001/GPSProxyService?wsdl)
I am deploying this in WebLogic 11g . Would there be any reason with @WebServiceProvider to WebLogic 11g. Because this is too simple Webservice . but not working properly.
Pls . helpe me for this...
Updated web.xml looks like below.

xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">

<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
