i getting null pointer exception in soap :-

<s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">    <s:body>       <s:fault xmlns:ns4="http://www.w3.org/2003/05/soap-envelope">          <faultcode>s:server</faultcode>          <faultstring>java.lang.nullpointerexception</faultstring>       </s:fault>    </s:body> </s:envelope> 

can try run code , tell me mistakes? need add few jax-ws jars in lib run code.

i have followed few online tutorials on how deploy jax-ws web service in tomcat. have created web service class , annotated @webservice, written web.xml , sun-jaxws.xml file, packaged files (plus jax-ws jar files) .war file, , deployed tomcat. appears working, can load wsdl file in browser pointed @ tomcat.
