> I have some important doubts on ServiceClient and RPCServiceClient classes.
> In axis I used to do something like this: listProduct = (Vector<Object>) call.invoke(new
Object[]{});
> When I migrated to axis2 I thought that ServiceClient was the easiest way to invoke a
method just as I did in axis.
> But I find out that I'm forced to use OMElement for parameters and invocation's result
in this way (MyCalcClient.java):
> 		try{
> 			ServiceClient serviceClient = new ServiceClient();
> 			serviceClient.setOptions(options);
> 			OMFactory fac = OMAbstractFactory.getOMFactory();
> 			OMNamespace omNs = fac.createOMNamespace("http://www.cal.com/calc", "calc");
> 			OMElement payload = fac.createOMElement(opStr, omNs);
> 			OMElement param1OM = fac.createOMElement("param1", omNs);
> 			OMElement param2OM = fac.createOMElement("param2", omNs);
> 			param1OM.setText(Integer.toString(pi1));
> 			param2OM.setText(Integer.toString(pi2));
> 			payload.addChild(param1OM);
> 			payload.addChild(param2OM);			
> 			serviceClient.setOptions(options);
> 			OMElement result = serviceClient.sendReceive(payload);
> 			System.out.println(result.toString());
> 			
> 		}catch(AxisFault af){af.printStackTrace();}
> and this is not very good if you have complex object returned by methods and complex
parameters. 
> Looking at RPCServiceClient i found out an easiest way (class RPC_MyCalcClient.java):
> try{
> 			String opName="add";
> 			EndpointReference targetEPR = new EndpointReference("http://localhost:8080/axis2/services/RPCCalcService/");
> 			Options options = new Options();
> 			options.setTo(targetEPR);
> 			options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
> 			ConfigurationContext configContext=ConfigurationContextFactory.createConfigurationContextFromFileSystem(null,null);

> 			RPCServiceClient sender = new RPCServiceClient(configContext, null);
> 			sender.setOptions(options);
> 			ArrayList<Integer> arg = new ArrayList<Integer>();
> 			Integer a  = new Integer("100"); 
> 			arg.add(a);
> 			Integer b = new Integer("200");
> 			arg.add(b);
> 			QName opAdd = new QName("http:///xsd", "add");
> 			Object[] params = new Object[] { a, b };
> 			Class[] returnTypes = new Class[] { Integer.class };
> 			Object[] response = sender.invokeBlocking(opAdd, params, returnTypes);
> 			Integer result = (Integer) response[0];
> 			if (result == null) {System.out.println("Null");}
> 			else System.out.println("Result "+ result.toString());
> 		}catch(AxisFault a){a.printStackTrace();} 
> If I want something like that: Object[] response = sender.invokeBlocking(opAdd, params,
returnTypes);
> I'm forced to use RPCServiceClient?
> RPCServiceClient means that I'm using soap/rpc binding style? Soap/document-style is
supported in axis2?
> I've checked the examples in CalculatorService package, in this case a different tecnique
is used (CalcClient.java) and a SOAPEnvelope Object is returned by the method invocation:

> 	SOAPEnvelope result = opClient.getMessageContext(
> 					WSDLConstants.MESSAGE_LABEL_IN_VALUE).getEnvelope();
> How can I choose one of these different tecniques? 
> Please help me understanding more about and tell me where can I find documentation on
this issue.
> Many Thanks
