Hi all, In the past, i used Axis v1.4 WSDLtoJava to generate web service client classes.
Now, I upgraded to Axis2 and used wsdltojava but only two classes were generated - the stub and interface. Looks like the data types/params related classes did not genertae that the STUB refers to?? If so, which wsdltojava command need to be used to generate the classes related to the params and returnt ypes of a business method?? I have compilation errors with the Stub and need help. I looked at the stub code and I see that there are many SOAP envelope related code UNLIKE in the stub generated in Axis 1.4. Also, the retun type and params of a business method are treated as classes. Why is that? I want a simple webservice client? How to accomplish it? - Do I need to use CXF instead of Axis2? The steps followed are below: 1) Excerpt of the WSDL: < <http://10.5.20.126:8206/cds-wsclient/cds-service?wsdl#> <?xml version="1.0"?> <wsdl:definitions targetNamespace="http://client.xyz"; name="TestInterface" xmlns:ns1="http://schemas.xmlsoap.org/soap/http"; xmlns:soap=" http://schemas.xmlsoap.org/wsdl/soap/"; xmlns:tns=" http://client.cds.med.va.gov"; xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"; xmlns:xsd="http://www.w3.org/2001/XMLSchema";> <http://10.5.20.126:8206/cds-wsclient/cds-service?wsdl#><wsdl:message name=" readData"> <http://10.5.20.126:8206/cds-wsclient/cds-service?wsdl#>< wsdl:part type="xsd:string" name="in0"/><wsdl:part type="xsd:string" name=" in1"/><wsdl:part type="xsd:string" name="in2"/></wsdl:message><wsdl:message name="readDataResponse"> <http://10.5.20.126:8206/cds-wsclient/cds-service?wsdl#><wsdl:part type=" xsd:string" name="out"/></wsdl:message> 2a) To generate client classes from wsdl: %AXIS2_HOME%\bin\WSDL2Java -uri <wsdl file path> -p <package name> -u -s This created a interface and a stub. 2b) I had to add the following dependenicesin maven pom to avoid some of the compilation errors in the stub: <dependency> <groupId>axis</groupId> <artifactId>axis</artifactId> <version>1.6.2</version> </dependency> <dependency> <groupId>org.apache.ws.commons.axiom</groupId> <artifactId>axiom-api</artifactId> <version>1.2.8</version> </dependency> <dependency> <groupId>org.apache.ws.commons.axiom</groupId> <artifactId>axiom-impl</artifactId> <version>1.2.8</version> </dependency> 3) The stub has still issues: The auto generated stub had the following signature for the business method: public readDataResponse readData(readData) throws java.rmi.RemoteException I changed it to: public String readData(String in0, String in1, String int2) throws java.rmi.RemoteException Now it still has compilation issues since toenvelope() is expecting a readData object insted of the in params list. Below is the business method and toenvelope method: private org.apache.axiom.soap.SOAPEnvelope toEnvelope(org.apache.axiom.soap.SOAPFactory factory, ReadData param, boolean optimizeContent, javax.xml.namespace.QName methodQName) throws org.apache.axis2.AxisFault{ try{ org.apache.axiom.soap.SOAPEnvelope emptyEnvelope = factory.getDefaultEnvelope(); emptyEnvelope.getBody().addChild(param.getOMElement(gov.va.med.cds.client.ReadClinicalData.MY_QNAME,factory)); return emptyEnvelope; } catch(org.apache.axis2.databinding.ADBException e){ throw org.apache.axis2.AxisFault.makeFault(e); } } public String readData(String in0, String in1, String int2) throws java.rmi.RemoteException org.apache.axis2.context.MessageContext _messageContext = null; try{ org.apache.axis2.client.OperationClient _operationClient = _serviceClient.createClient(_operations[0].getName()); _operationClient.getOptions().setAction("http://xyz/readData";); _operationClient.getOptions().setExceptionToBeThrownOnSOAPFault(true); addPropertyToOperationClient(_operationClient,org.apache.axis2.description.WSDL2Constants.ATTR_WHTTP_QUERY_PARAMETER_SEPARATOR,"&"); // create a message context _messageContext = new org.apache.axis2.context.MessageContext(); // create SOAP envelope with that payload org.apache.axiom.soap.SOAPEnvelope env = null; env = toEnvelope(getFactory(_operationClient.getOptions().getSoapVersionURI()), in0, in1, in2, optimizeContent(new javax.xml.namespace.QName("http://client.xyz";, "readData")), new javax.xml.namespace.QName("http://client.xyz";, "readData")); //adding SOAP soap_headers _serviceClient.addHeadersToEnvelope(env); // set the message context with that soap envelope _messageContext.setEnvelope(env); // add the message contxt to the operation client _operationClient.addMessageContext(_messageContext); //execute the operation client _operationClient.execute(true); org.apache.axis2.context.MessageContext _returnMessageContext = _operationClient.getMessageContext( org.apache.axis2.wsdl.WSDLConstants.MESSAGE_LABEL_IN_VALUE); org.apache.axiom.soap.SOAPEnvelope _returnEnv = _returnMessageContext.getEnvelope(); java.lang.Object object = fromOM( _returnEnv.getBody().getFirstElement() , String.class, getEnvelopeNamespaces(_returnEnv)); return (String)object; }catch(org.apache.axis2.AxisFault f){ org.apache.axiom.om.OMElement faultElt = f.getDetail(); if (faultElt!=null){ if (faultExceptionNameMap.containsKey(new org.apache.axis2.client.FaultMapKey(faultElt.getQName(),"readData"))){ //make the fault by reflection try{ java.lang.String exceptionClassName = (java.lang.String)faultExceptionClassNameMap.get(new org.apache.axis2.client.FaultMapKey(faultElt.getQName(),"readData")); java.lang.Class exceptionClass = java.lang.Class.forName(exceptionClassName); java.lang.reflect.Constructor constructor = exceptionClass.getConstructor(String.class); java.lang.Exception ex = (java.lang.Exception) constructor.newInstance(f.getMessage()); //message class java.lang.String messageClassName = (java.lang.String)faultMessageMap.get(new org.apache.axis2.client.FaultMapKey(faultElt.getQName(),"readData")); java.lang.Class messageClass = java.lang.Class.forName(messageClassName); java.lang.Object messageObject = fromOM(faultElt,messageClass,null); java.lang.reflect.Method m = exceptionClass.getMethod("setFaultMessage", new java.lang.Class[]{messageClass}); m.invoke(ex,new java.lang.Object[]{messageObject}); } 4) Could you provide the client exmaple to invoke the stub andits business methods? Thanks in advance.
