WebService with CXF to develop very simple, thanks to the hard work the team apache CXF. Here I am to practice the process of CXF to others.

This is the way of programming the full release WebService example, be regarded as entry-level Hello world.

WS server:

(1) HelloWorld.java Interface

package com.xxx.ws.code.server;

import javax.jws.WebService;

@WebService
public interface HelloWorld {
        String sayHi(String text);
}

(2) implementation class HelloWorldImpl.java

package com.xxx.ws.code.server.impl;

import javax.jws.WebService;

import com.xxx.ws.code.server.HelloWorld;

@WebService(endpointInterface = "com.xxx.ws.code.server.HelloWorld",
        serviceName = "HelloWorld")
public class HelloWorldImpl implements HelloWorld {
        
        public String sayHi(String text) {
        System.out.println("sayHi called");
        return "Hello " + text;
    }

}

(3) published web service

package com.xxx.ws.code.server;

//import javax.xml.ws.Endpoint;

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

import com.xxx.ws.code.server.impl.HelloWorldImpl;

public class RunCXFServer {

    protected RunCXFServer() throws Exception {
        // START SNIPPET: publish
        System.out.println("Starting Server");
        HelloWorldImpl implementor = new HelloWorldImpl();
        JaxWsServerFactoryBean svrFactory = new JaxWsServerFactoryBean();
        svrFactory.setServiceClass(HelloWorld.class);
        svrFactory.setAddress("http://localhost:8002/helloWorld");
        svrFactory.setServiceBean(implementor);
        svrFactory.getInInterceptors().add(new LoggingInInterceptor());
        svrFactory.getOutInterceptors().add(new LoggingOutInterceptor());
        svrFactory.create();

        // END SNIPPET: publish
    }

    public static void main(String args[]) throws Exception {
        new RunCXFServer();
        System.out.println("Server ready...");
    }
}

(4) Run RunCXFServer

http://localhost:8002/helloWorld?wsdl can see the output saop envelope.

Preparation of client calls WebService

package com.xxx.ws.code.client;

//import javax.xml.namespace.QName;
//import javax.xml.ws.Service;
//import javax.xml.ws.soap.SOAPBinding;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;

import com.xxx.ws.code.server.HelloWorld;

public class RunCXFCodeClient {
        public static void main(String args[]) throws Exception {

        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
        factory.getInInterceptors().add(new LoggingInInterceptor());
        factory.getOutInterceptors().add(new LoggingOutInterceptor());
        factory.setServiceClass(HelloWorld.class);
        factory.setAddress("http://localhost:8002/helloWorld");
        HelloWorld client = (HelloWorld) factory.create();

        String reply = client.sayHi("HI");
        System.out.println("Server said: " + reply);

    }
        
}
