Class WebServiceClient

java.lang.Object

javolution.xml.ws.WebServiceClient

public abstract class WebServiceClient
extends Object

This class provides a simple web service client capable of leveraging Javolution XML marshalling/unmarshalling.

Sub-classes may work from WSDL files, XMLFormat or directly with the XML streams (StAX). For example:

     private static class HelloWorld extends WebServiceClient  {
         protected void writeRequest(XMLObjectWriter out) throws XMLStreamException {
             XMLStreamWriter xml = out.getStreamWriter();
             xml.writeDefaultNamespace("http://www.openuri.org/");
             xml.writeEmptyElement("helloWorld"); // Operation name.
         }
         protected void readResponse(XMLObjectReader in) throws XMLStreamException {
             XMLStreamReader xml = in.getStreamReader();
             xml.require(START_ELEMENT, "http://www.openuri.org/", "string");
             xml.next(); // Move to character content.
             System.out.println(xml.getText());
         }
     }
     WebServiceClient ws = new HelloWorld().setAddress("http://acme.com:80/HelloWorld.jws");
     ws.invoke();
     
      > Hello World!
