Hello, We are trying to build a C++ client to connect to WCF services using basicHttpBinding.
I am able to use WSDL2C to generate the C++ stub and use the stub calls to send request to the service and get result object back. But I am unable to get the Fault object back. It seems to me the generated stub can not handle the Soap Fault object. I am wondering if any one can give me some help for receiving Fault object. My service WSDL contains the service call GetData(string) and fault class BatchService: <wsdl:binding name="WSHttpBinding_IBatchService" type="i0:IBatchService"> <wsp:PolicyReference URI="#WSHttpBinding_IBatchService_policy" /> <soap12:binding transport="http://schemas.xmlsoap.org/soap/http"; /> <wsdl:operation name="GetData"> <soap12:operation soapAction="" style="document" /> <wsdl:input> <wsp:PolicyReference URI="#WSHttpBinding_IBatchService_GetData_Input_policy" /> <soap12:body use="literal" /> </wsdl:input> <wsdl:output> <wsp:PolicyReference URI="#WSHttpBinding_IBatchService_GetData_output_policy" /> <soap12:body use="literal" /> </wsdl:output> <wsdl:fault name="BatchFaultFault"> <wsp:PolicyReference URI="#WSHttpBinding_IBatchService_GetData_BatchFaultFault_Fault" /> <soap12:fault use="literal" name="BatchFaultFault" namespace="" /> </wsdl:fault> </wsdl:operation> </wsdl:binding> WSDL2C does generate the following files: axis2_stub_BatchService.[hc] adb_GetData.[hc] adb_BatchFault.[hc] However the stub request function axis2_stub_op_BatchService_GetData() inside the geratated file axis2_stub_BatchService.c does not check if there is any fault. The function has the following lines: ret_node = axis2_svc_client_send_receive_with_op_qname( svc_client, env, op_qname, payload); ret_val = adb_GetDataResponse_create(env); if(adb_GetDataResponse_deserialize(ret_val, env, &ret_node, NULL, AXIS2_FALSE ) == AXIS2_FAILURE) If the soap xml is BatchFault instead of regular return object, the adb_GetDataResponse_deserialize() call would fail and axis2_stub_op_BatchService_GetData() call return NULL. Thus We are unable to get the Fault information. If I add "xml = axiom_node_sub_tree_to_string(ret_node, env);" after the line of ret_node = axis2_svc_client_send_receive_with_op_qname( svc_client, env, op_qname, payload); I do see the return XML as: <s:Fault xmlns:s="http://schemas.xmlsoap.org/soap/envelope/";> <faultcode>s:Client</faultcode> <faultstring xmlns:xml="http://www.w3.org/XML/1998/namespace"; xml:lang="en-US"> The creator of this fault did not specify a Reason.</faultstring> <detail> <BatchFault xmlns="http://schemas.datacontract.org/2004/07/eGlue.WCF.Common"; xmlns:i="http://www.w3.org/2001/XMLSchema-instance";> <ErrorCode>1</ErrorCode> <ErrorMessage>Batch Fault: Input value is too big. Expected value is less than 1000</ErrorMessage> </BatchFault> </detail> </s:Fault> So should the stub provide some mechnism to return the custom Fault object or throw exception of custom Fault object? Also I tried to modify the generated stub code to get the BatchFault object from the return node. But I am still unable to deserialize into BatchFault object. Both xmls for subtree of <detail> and <BatchFault> are empty and adb_BatchFault_deserialize() call fails also. Can you please check what is wrong in my code? The code that I added into axis2_stub_op_BatchService_GetData() function is as following: if(adb_GetDataResponse_deserialize(ret_val, env, &ret_node, NULL, AXIS2_FALSE ) == AXIS2_FAILURE) { if ( axis2_svc_client_get_last_response_has_fault(svc_client, env) ) { axiom_element_t* data_element = axiom_node_get_data_element(ret_node, env); if ( data_element != NULL ) { adb_BatchFault_t* fault = NULL; axutil_qname_t* detail_qname = NULL; axutil_qname_t* batch_fault_qname = NULL; axiom_element_t * detail_elementp = NULL; axiom_node_t * detail_nodep = axiom_node_create(env); axiom_element_t * batch_fault_elementp = NULL; axiom_node_t * batch_fault_nodep = axiom_node_create(env); detail_qname = axutil_qname_create(env, "detail", NULL, ""); batch_fault_qname = axutil_qname_create(env, "BatchFault", NULL, ""); detail_elementp = axiom_element_get_first_child_with_qname(data_element, env, detail_qname, ret_node, &detail_nodep); if ( detail_elementp != NULL ) { xml = axiom_node_sub_tree_to_string(detail_elementp, env); batch_fault_elementp = axiom_element_get_first_child_with_qname(detail_elementp, env, batch_fault_qname, ret_node, &batch_fault_nodep); if ( batch_fault_elementp != NULL ) { xml = axiom_node_sub_tree_to_string(batch_fault_elementp, env); fault = adb_BatchFault_create(env); if ( adb_BatchFault_deserialize(fault, env, &batch_fault_nodep, NULL, AXIS2_FALSE ) == AXIS2_FAILURE) { printf("Got unknown exception" ); } else { printf("BatchFault: %s\n", adb_BatchFault_get_ErrorMessage(fault, env)); } } } Thank you very much for your help.
