Problem while calling a Webservice from a Stand alone java program

Question

Hello Everyone,
I am using a java program to call a webservice as follows. For this I have generated the client proxy definition for Stand alone proxy using NWDS.
Now when I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
The java code to call the webservice is as follows.
public class ZMATRDESCProxyClient {
     public static void main(String[] args) throws Exception {
          Z_MATRDESC_WSDService ws = new Z_MATRDESC_WSDServiceImpl();
          Z_MATRDESC_WSD port = (Z_MATRDESC_WSD)ws.getLogicalPort("Z_MATRDESC_WSDSoapBinding",Z_MATRDESC_WSD.class);
          String res = port.zXiTestGetMatrDesc("ABCD134");
          System.out.print(res);
The result I am getting is :
Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory
<b>Material Not Found</b> -
> This is the output of webservice method and it is right.
Can any one please let me know why I am getting the warning and error message and how can I fix this.
Thanks

Hi Abinash,
I have the same problem. Have you solve that problem?
I am using a java program to call a webservice too. And I have generated the client proxy definition for Stand alone proxy using NWDS. When I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
The java code to call the webservice is as follows.
MIDadosPessoaisSyncService service = new MIDadosPessoaisSyncServiceImpl();
MIDadosPessoaisSync port = service.getLogicalPort("MIDadosPessoaisSyncPort");
port._setProperty("javax.xml.rpc.security.auth.username","xpto");
port._setProperty("javax.xml.rpc.security.auth.password","xpto");
String out = port.MIDadosPessoaisSync("xpto", "xpto");
System.out.println(out);
The result I am getting is :
Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory
<b>The result of the WS is correct!!!</b>
The Java project does not have any warning. But the stand alone proxy project has following warnings associated with it.
This method has a constructor name     MIDadosPessoaisSync.java     
The import javax.xml.rpc.holders is never used     MIDadosPessoaisSyncBindingStub.java     
The import javax.xml.rpc.encoding is never used     MIDadosPessoaisSyncBindingStub.java     
The constructor BaseRuntimeException(ResourceAccessor, String, Throwable) is deprecated     MIDadosPessoaisSyncBindingStub.java
It is very similar with your problem, could you help me?
Thanks
