public String retr_subscriber(String msisdn,String id)
        {       System.out.println("0");
                try
                {
                System.out.println("A");
                //ConfigurationContext ctx = ConfigurationContextFactory.createConfigurationContextFromFileSystem("/home/ussd_src/self_care/axis2/axis2-1.5/repository/");
                ConfigurationContext ctx = ConfigurationContextFactory.createDefaultConfigurationContext();
                SAM_BR_Service_v1_0Stub stub =new SAM_BR_Service_v1_0Stub(ctx,"http://10.16.4.15:8180/axis2/services/SAM_BR_Service_v1_0");
                ServiceClient sClient = stub._getServiceClient();
                sClient.engageModule("rampart");
                System.out.println("B");

                //ServiceClient sClient=new ServiceClient(ctx,stub);

                Options options = sClient.getOptions();
                HttpTransportProperties.Authenticator   auth = new HttpTransportProperties.Authenticator();
                auth.setPreemptiveAuthentication(true);
                auth.setUsername("unitech1");
                auth.setPassword("unitecha");
                options.setProperty(org.apache.axis2.transport.http.HTTPConstants.AUTHENTICATE, auth);


//            options.setUserName("unitech1");
 //           options.setPassword("unitecha");

                sClient.setOptions(options);

                System.out.println("C");
        /*      ((Stub) stub)._setProperty(Call.USERNAME_PROPERTY, "unitech1");
                ((Stub) stub)._setProperty(Call.PASSWORD_PROPERTY, "unitecha");*/
                BalanceRetrAllDocument req = BalanceRetrAllDocument.Factory.newInstance();
                BalanceRetrAllReqType data = req.addNewBalanceRetrAll();
                data.setSubscriberID(msisdn);
                data.setAgentID("spice_ussd");
                BalanceRetrAllRespDocument resp = stub.balanceRetrAll(req);
                BalanceRetrAllRespType bal=resp.getBalanceRetrAllResp();
                System.out.println("Request Message :");
                System.out.println("SubscriberID :"+ data.getSubscriberID() + "\nAgentID :" + data.getAgentID());
                System.out.println("Code :"+ bal.getStatusCode() + "\nBalanceBucket Table :" + bal.getBalanceBucketTable()+"\nBalance Version :"+bal.getBalanceVersion()+"\nBalanceBucket Max Rows :"+bal.getBalanceBucketMaxRows()+"\ngetBalanceSubscriberOrGroup :"+bal.getBalanceSubscriberOrGroup());
}

can you post your code.

@manish250- Sorry this code is too heavy for me i am also a begginer in servlets and JSP. But i think your Servlets service() method is throwing an exception and i think there can be an mistake in the service() method and not the one which you have posted. Or i think you must have forgotton to throw an exception , do this

public void service(HttpServletRequest req, HttpServletResponse res) throws IOException,ServletException

sorry but this is not the problem you are telling

You need to post the whole stack trace. If you read it carefully you will find that it tells you which of your files has the error.
