Hello, I am having a problem executing queries from my Java code. I have generated the SforceServiceStub.java from the wsdl file, and I am able to connect to the salesforce server successfully. Moreover, the describeGlobal()
function runs great, and returns all the object types. However, when executing
queries, I'm getting the error:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

my code is as follows:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
public class SampleLogin {    
   
    public static void main(String args[])  {      
     
            SforceServiceStub stub = new SforceServiceStub();
            Options options = stub._getServiceClient().getOptions();
            options.setProperty(HTTPConstants.MC_ACCEPT_GZIP, Boolean.TRUE);
            options.setProperty(HTTPConstants.MC_GZIP_REQUEST, Boolean.TRUE);

            Login lg = new Login();
            lg.setPassword("********");
            lg.setUsername("*******");
            LoginScopeHeader lsh = null;         
            LoginResponse response = stub.login(lg, lsh);
            LoginResult lr  = response.getResult();
                    
            SessionHeader sh = new SessionHeader();
            sh.setSessionId(lr.getSessionId());          
            stub = new SforceServiceStub(lr.getServerUrl());
            options = stub._getServiceClient().getOptions();
            options.setProperty(HTTPConstants.MC_ACCEPT_GZIP, Boolean.TRUE);
            options.setProperty(HTTPConstants.MC_GZIP_REQUEST, Boolean.TRUE);
          
           QueryOptions qOptions = new QueryOptions();
            qOptions.setBatchSize(200);          
            Query q = new Query();
            q.setQueryString("select AccountId from Contact");
            QueryResponse qResponse = stub.query(q, sh, qOptions, null);          
            QueryResult qr = qResponse.getResult();
 }

Can anyone suggest what am I doing wrong, and point in the right direction ?

Thanks a bunch ahead,
