Ok it finally worked but I am got frustrated by looking at solution. Aparently | Call call = service.createCall(); | call.setOperationName(new QName ("http://xmlme.com/WebServices", "DvdBox")); | is not sufficient and will give the stack trace given in my last reply. However when I tried this convoluted approach to acquire my call object it worked without the stack trace: | Call[] calls = service.getCalls(new QName("http://xmlme.com/WebServices";, "AmazonBoxSoap")); | for(int ii=0; ii<calls.length; ii++) { | Call call = calls[ii]; | QName opName = call.getOperationName(); | if(opName.getLocalPart().equals("DvdBox")) { | DvdBox req = new DvdBox("Disney"); | call.setProperty(Call.SOAPACTION_USE_PROPERTY, Boolean.TRUE); | call.setProperty(Call.SOAPACTION_URI_PROPERTY, "http://xmlme.com/WebServices/DvdBox"); | Object response = call.invoke(new Object[] {req}); | if(response instanceof DvdBoxResponse) { | DvdBoxResponse result = (DvdBoxResponse)response; | System.out.println("Finished" + result.getDvdBoxResult()); | } | } | Here is the complete client code in case somebody runs into this issue: | URL wsdlURL = new URL("http://www.xmlme.com/WSAmazonBox.asmx?WSDL"); | ServiceFactoryImpl servFactory = new ServiceFactoryImpl(); | URL mappingURL = new File("jaxrpc-mapping.xml").toURL(); | QName qname = new QName("http://xmlme.com/WebServices";, "AmazonBox"); | ServiceImpl service = (ServiceImpl)servFactory.createService(wsdlURL, qname, mappingURL); | Call[] calls = service.getCalls(new QName("http://xmlme.com/WebServices";, "AmazonBoxSoap")); | for(int ii=0; ii<calls.length; ii++) { | Call call = calls[ii]; | QName opName = call.getOperationName(); | if(opName.getLocalPart().equals("DvdBox")) { | DvdBox req = new DvdBox("Disney"); | call.setProperty(Call.SOAPACTION_USE_PROPERTY, Boolean.TRUE); | call.setProperty(Call.SOAPACTION_URI_PROPERTY, "http://xmlme.com/WebServices/DvdBox"); | Object response = call.invoke(new Object[] {req}); | if(response instanceof DvdBoxResponse) { | DvdBoxResponse result = (DvdBoxResponse)response; | System.out.println("Finished" + result.getDvdBoxResult()); | } | } | } | Have a good weekend!
