Exception while accessing web service through code

Question

I have a web service developed using AXIS deployed on Weblogic 8.1
Another web application cotaining GUI deployed on Weblogic 10 tries to access this web service through code.
This piece of code to invoke the web service is written in Action Class present inside web application. (Struts is used in GUI based web app)
When the code tries to invoke web service I am getting following error.
(401)Unauthorized xxx

     at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:415)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:727)
The web service URL is as follows:
http://10.140.96.5:7808/services/ucs77_1/ProcessOfficialChangeSave77_1-v0001.soap
However
When I try to hit the webservice URL directly on browser login window appears where same username/password I provide which are passed in code to invoke the web service. I get the success page indicating that web service is invoked on hitting enter.
The method used in UCS77_1ProcessOfficialChangeSaveDetailsAction.java to invoke web service is as follows:
public String invokeAx
               String xmlMessage,
               String webServiceURL,
               String webServiceOperation,
               String username,
               String password)
          String xmlResponse = null;
          Call webServiceCall = null;
          InputStream input = new ByteArrayInputStream(xmlMessage.getBytes());
          Service service = new Service();
          try
               webServiceCall = (Call) service.createCall();
               SOAPEnvelope env = new SOAPEnvelope(input);
               SOAPEnvelope resEnv = null;
               webServiceCall.setTargetEndpointAddress(new URL(webServiceURL));
               webServiceCall.setOperationName(new QName(webServiceOperation));
               webServiceCall.setUsername(username);
               webServiceCall.setPassword(password);               
               try
                    resEnv = webServiceCall.invoke(env);
               catch (AxisFault e)
                    e.printStackTrace();
                    Message responseMessage = webServiceCall.getResponseMessage();
                    SOAPEnvelope soapXml = (SOAPEnvelope) responseMessage.getSOAPEnvelope();
                    xmlResponse = new String(soapXml.toString().getBytes(AppConstants.UTF8),AppConstants.UTF8);     
               if (xmlResponse == null)
                    xmlResponse = resEnv.toString();
          catch (Exception e1)
               e1.printStackTrace();
          return xmlResponse;
Both the weblogic server reside on two different AIX machines.
Can anybody tell what's the problem while invoking web service through code?

Answer 1

time to look into the gateway logs as stated by the fault ..
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><SOAP-ENV:Fault><faultcode xmlns:p="http://schemas.oblix.com/ws/2003/08/Faults">c</faultcode><faultstring>Step execution failed with an exception</faultstring><detail></detail></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope>
looks like the cipher step might have failed
