http://nagoya.apache.org/bugzilla/show_bug.cgi?id=12758 Deserialization of complex classes throws SAXException Summary: Deserialization of complex classes throws SAXException Product: Axis Version: current (nightly) Platform: PC OS/Version: Linux Status: NEW Severity: Normal Priority: Other Component: Serialization/Deserialization AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I'm using what I believe to be the latest version of AXIS on Linux (I downloaded "xml-axis-rc1-bin.zip" yesterday - 16 Sept 02) and trying to talk to a Borland SOAP server with 5 different services. I used WSDL2Java to generate all the classes I need from the following service: http://tims.moveyourselftrailer.com.au:8000/scripts/SackTruck.dll/wsdl/ISackTruc k I used this snippet of code to try and access the simplest of the ports, just as worked previously for another service on the same server: ISackTruckservice locator = new ISackTruckserviceLocator(); ISackTruck client = locator.getISackTruckPort(); Object fees = client.getSackTruckFees(); And got: org.xml.sax.SAXException: operation description is missing parameter description! at org.apache.axis.message.RPCHandler.onStartChild(RPCHandler.java:220) at org.apache.axis.encoding.DeserializationContextImpl.startElement (DeserializationContextImpl.java:883) at org.apache.axis.message.SAX2EventRecorder.replay (SAX2EventRecorder.java:158) at org.apache.axis.message.MessageElement.publishToHandler (MessageElement.java:681) at org.apache.axis.message.RPCElement.deserialize(RPCElement.java:244) at org.apache.axis.message.RPCElement.getParams(RPCElement.java:268) at org.apache.axis.client.Call.invoke(Call.java:1862) at org.apache.axis.client.Call.invoke(Call.java:1768) at org.apache.axis.client.Call.invoke(Call.java:1306) at com.touchcorp.soap.isacktruck.ISackTruckbindingStub.getSackTruckFees (ISackTruckbindingStub.java:228) at com.touchcorp.remote.party.ISackTruckService.getSackTruckFees (ISackTruckService.java:96) at com.touchcorp.remote.party.ISackTruckService.main (ISackTruckService.java:133) [ERROR] Call - -Exception: <org.xml.sax.SAXException: operation description is missing parameter description!> Exception in thread "main" AxisFault faultCode: {http://xml.apache.org/axis/}Server.userException faultString: org.xml.sax.SAXException: operation description is missing parameter description! faultActor: null faultDetail: stackTrace: org.xml.sax.SAXException: operation description is missing parameter description! at org.apache.axis.message.RPCHandler.onStartChild(RPCHandler.java:220) at org.apache.axis.encoding.DeserializationContextImpl.startElement (DeserializationContextImpl.java:883) at org.apache.axis.message.SAX2EventRecorder.replay (SAX2EventRecorder.java:158) at org.apache.axis.message.MessageElement.publishToHandler (MessageElement.java:681) at org.apache.axis.message.RPCElement.deserialize(RPCElement.java:244) at org.apache.axis.message.RPCElement.getParams(RPCElement.java:268) at org.apache.axis.client.Call.invoke(Call.java:1862) at org.apache.axis.client.Call.invoke(Call.java:1768) at org.apache.axis.client.Call.invoke(Call.java:1306) at com.touchcorp.soap.isacktruck.ISackTruckbindingStub.getSackTruckFees (ISackTruckbindingStub.java:228) at com.touchcorp.remote.party.ISackTruckService.getSackTruckFees (ISackTruckService.java:96) at com.touchcorp.remote.party.ISackTruckService.main (ISackTruckService.java:133) org.xml.sax.SAXException: operation description is missing parameter description! org.xml.sax.SAXException: operation description is missing parameter description! at org.apache.axis.message.RPCHandler.onStartChild(RPCHandler.java:220) at org.apache.axis.encoding.DeserializationContextImpl.startElement (DeserializationContextImpl.java:883) at org.apache.axis.message.SAX2EventRecorder.replay (SAX2EventRecorder.java:158) at org.apache.axis.message.MessageElement.publishToHandler (MessageElement.java:681) at org.apache.axis.message.RPCElement.deserialize(RPCElement.java:244) at org.apache.axis.message.RPCElement.getParams(RPCElement.java:268) at org.apache.axis.client.Call.invoke(Call.java:1862) at org.apache.axis.client.Call.invoke(Call.java:1768) at org.apache.axis.client.Call.invoke(Call.java:1306) at com.touchcorp.soap.isacktruck.ISackTruckbindingStub.getSackTruckFees (ISackTruckbindingStub.java:228) at com.touchcorp.remote.party.ISackTruckService.getSackTruckFees (ISackTruckService.java:96) at com.touchcorp.remote.party.ISackTruckService.main (ISackTruckService.java:133) But, if I go back and use Apache SOAP directly, everything seems to work just fine. I am *not* using an operation style of "rpc" when I call via SOAP directly. My code looks more like this: URL url = new URL(locator.getISackTruckPortAddress()); String uri = "urn:uSackTruckFee"; String method = "getSackTruckFees"; Class type = com.touchcorp.soap.isacktruck.TSackTruckFeeInfo.class; Vector args = new Vector(); // get short version of type class name String typeName = type.getName(); int index = typeName.lastIndexOf("."); if (index > 0) typeName = typeName.substring(index+1); // set up bean mappings SOAPMappingRegistry registry = new SOAPMappingRegistry(); BeanSerializer serializer = new BeanSerializer(); registry.mapTypes(Constants.NS_URI_SOAP_ENC, new QName(uri, typeName), type, serializer, serializer); // build the call Call call = new Call(); call.setSOAPMappingRegistry(registry); call.setTargetObjectURI(uri); call.setMethodName(method); call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC); call.setParams(args); // make the call Response response = call.invoke(url, ""); Help! I have attached some of the relevant WSDL2Java-generated code below.
