Java-将SOAP与从WSDL类生成的结合使用

Question

I have a WSDL schema link. With NetBeans I generated classes from this schema. But I can't understand, how to use it to send request to server? There is a XXXImplService extends Service class generated by NetBeans, should I use it? How?

As I think, I need just to create objects (which match WSDL methods and classes), set necessary properties and somehow transform this objects into a text of request, then send it with and get text response, which I can transform into classes. Is this true?

Answer 1

of course you have to use the WSDL , follow below steps for a complete client app for a Java web service (JAX-WS):

assuming you have a Web Service like this:

@WebService
public class Hello {
    private String message = new String("Hello, ");

    public void Hello() {}

    @WebMethod
    public String sayHello(String name) {
        return message + name + ".";
    }
}

1. Uses the javax.xml.ws.WebServiceRef annotation to declare a reference to a web service. @WebServiceRef uses the wsdlLocation element to specify the URI of the deployed service's WSDL file:

   @WebServiceRef(wsdlLocation="http://localhost:8080/helloservice/hello?wsdl") static HelloService service;

2. Retrieves a proxy to the service, also known as a port, by invoking getHelloPort on the service.

   Hello port = service.getHelloPort(); The port implements the SEI defined by the service.

3. Invokes the port's sayHello method, passing to the service a name.

    String response = port.sayHello(name); 

EDIT: (request in comments) if the web service request for basic authentication and want to pass a username and password you can pass them like this (there are other ways also):

import java.net.Authenticator;
import java.net.PasswordAuthentication;

Authenticator authenticator = new Authenticator() 
{
    @Override
    protected PasswordAuthentication getPasswordAuthentication()
    {
        return new PasswordAuthentication("usr", "pass".toCharArray());
    }
};

Authenticator.setDefault(authenticator );

however if you want authentication in application level not on basic HTTP this link can be useful.

You have to implement your code in this generated service impl and web method now. So when you will be calling the service end point and a specific method, through a web service client ( SOAP UI etc), these generated classes will take the call and route through service impl, to your implementation.

This tutorial will help you to do it step by step. Since you have already created stub classes, skip the first part. Focus on "Web service invocation" section.
