Hello All,

I am facing a problem when is using DII client to invoke a webservice. 

Any help on this is appreciated.

Thanks in advance.

DII sample code:

RPCServiceClient svrClient = new RPCServiceClient(null,

                                         new 
QName("http://sys.com/MyGW","TestGateway";),
                                         "TestGatewaySoap");
                          
                        Object params[] = new Object[]{"test"};
//                      Object[] returnArray= svrClient.invokeBlocking(new

//                                                                              
                  "testMsgRecieve"), params,new Class[]{String.class});         
                        Object[] returnArray= svrClient.invokeBlocking(new

                          "testMsgRecieve"), params,new Class[]{String.class});
