WSDL2Java Stub and Call objects

[Wolfram Ditzer <di...@optel-informatik.de>]

Hello,

I use a wsdl2java to generate client classes. I also get a 
MyServiceStub.java, which prvides a interface to my webservices.

When I look into this list and a lot of example I see nearly nno one 
using ths Stub-classes. Instead all people uses Call objects created by 
 a Service object.

Shouldn´ t I use my Stub class MyServiceStub?

Can I have access to internal used Call objects of my Stub class?

Thanks Wolfram

In my experience, I use the sample code under samples/jaxrpc/hello.
In that example, I use the '--server-side --skeletonDeploy
true --deployScope Application' flags
to build the wsdl file, i.e. I use my own build.xml. The following files are
created:

Hello.java                 <-- RPC interface
HelloWorld.java            <-- Service interface
HelloWorldLocator.java     <-- Service locator, i.e. client stub locator

HelloBindingStub.java      <-- Client side stub

HelloBindingSkeleton.java  <-- Server side skeleton
HelloBindingImpl.java      <-- Server side implementation, WSDL2Java will
not overwrite it if it exits


The client program is HelloClient.java.  The original program uses
ServiceFactory to get the service, i.e.

    public static void main(String[] args) throws Exception {
        String UrlString =
"http://localhost:8080/axis/services/HelloPort?wsdl";
        String nameSpaceUri = "http://hello.jaxrpc.samples/";
        String serviceName = "HelloWorld";
        String portName = "HelloPort";

        URL helloWsdlUrl = new URL(UrlString);
// BEGIN
        ServiceFactory serviceFactory = ServiceFactory.newInstance();
        Service helloService = serviceFactory.createService(helloWsdlUrl,
                new QName(nameSpaceUri, serviceName));

        java.util.List list =
helloService.getHandlerRegistry().getHandlerChain(new QName(nameSpaceUri,
portName));
        list.add(new
javax.xml.rpc.handler.HandlerInfo(ClientHandler.class,null,null));

        Hello myProxy = (Hello) helloService.getPort(
                new QName(nameSpaceUri, portName),
                samples.jaxrpc.hello.Hello.class);
// END

        System.out.println(myProxy.sayHello("Buzz"));
    }

But you can use the following two lines of code to replace code between
'BEGIN' and 'END':

    HelloWorld helloService = new HelloWorldLocator();
    Hello      myProxy      = helloService.getHelloPort(helloWsdlUrl);
The HelloBindingStub is used internally in HelloWorldLocator.getHelloPort.

There is a bug in WSDL2Java that the default getHelloPort() it generates
does not work.  You have to use the
one that takes a URL.

This is somewhat explained in the user's guide.
