SOAP Web Services Example Using JAX-WS

Here is an Example for SOAP Web Services using JAX-WS

The Project Architecture is like this

Its a normal Java Project:
From Eclipse file--new--java project--SoapWSProj
And you know how to create the packages, classes etc. It has no external jars included.

ws.Demo.java
package ws;

import javax.jws.*;

@WebService
public interface Demo {

@WebMethod
public String helloWorld();

@WebMethod
public String hi(String name);

}

ws.DemoImpl

package ws;

import javax.jws.*;

@WebService(endpointInterface="ws.Demo")

public class DemoImpl implements Demo{

@Override

public String helloWorld() {

return "Hello World";

}

@Override

public String hi(String name) {

return "Hi "+name;

}

}

Product.java

package entities;

public class Product {

private int id;

private String pname;

private int cost;

public Product() {

super();

}

public Product(int id, String pname, int cost) {

super();

this.id = id;

this.pname = pname;

this.cost = cost;

}

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public String getPname() {

return pname;

}

public void setPname(String pname) {

this.pname = pname;

}

public int getCost() {

return cost;

}

public void setCost(int cost) {

this.cost = cost;

}

}

ProductDAO.java

package dao;

import java.util.ArrayList;

import java.util.List;

import entities.*;

public class ProductDAO {

public Product find(){

return new Product(101,"iphone", 60000);

}

public List<Product> findAll(){

 

List<Product> list = new ArrayList<Product>();

Product p1 = new Product(102,"mi",12000);

Product p2 = new Product(103,"MM",10000);

Product p3 = new Product(104,"Asus",15000);

list.add(p1);

list.add(p2);

list.add(p3);

return list;

 

}

}

 * ProductWS.java

package ws;

import java.util.List;

import javax.jws.WebMethod;
import javax.jws.WebService;

import entities.Product;

@WebService
public interface ProductWS  {

@WebMethod
    public Product find() ;

@WebMethod
public List<Product> findAll();
}

ProductWSImpl.java

package ws;

import java.util.List;

import javax.jws.WebService;

import entities.Product;

import dao.ProductDAO;

@WebService(endpointInterface="ws.ProductWS")

public class ProductWSImpl implements ProductWS{

ProductDAO dao=new ProductDAO();

@Override

public Product find() {

return this.dao.find();

}

@Override

public List<Product> findAll() {

return this.dao.findAll();

}

}

Main.java

package main;

import javax.jws.*;

import javax.xml.ws.Endpoint;

import ws.DemoImpl;

import ws.ProductWSImpl;

public class Main {

public static void main(String[] args) {

try {

Endpoint.publish("http://localhost:4791/ws/demo",new DemoImpl());

Endpoint.publish("http://localhost:4791/ws/product", new ProductWSImpl());

System.out.println("Done");

} catch (Exception e) {

System.out.println(e.getMessage());

}

}

}

Dear folks Create the project as shown above and create the classes as the order I wrote because you may get confusion if you you don't follow the order. 

Now click on run Main.java

The console Shows "Done"

Now you can check the soap based wsdl using "http://localhost:4791/ws/demo?wsdl" and 

for product webservices as "http://localhost:4791/ws/demo?product"

The next step is click on the project name SOAPWSProj---new---webservice client.

Give Service Destination as "http://localhost:4791/ws/demo?wsdl"

Now a new Project with name " SoapWs" is automatically generated in your eclipse as shown below

It includes the proxy objects,stub objects created by using wsdl file,ServiceLocator class. All these are client based classes

now create main package and create class inside it as it is already available above 

Main.java

package main;

import java.rmi.RemoteException;

import javax.xml.rpc.ServiceException;

import ws.*;

public class Main {

public static void main(String[] args) {

try {

DemoImplService demoImplService = new DemoImplServiceLocator();

Demo demo = demoImplService.getDemoImplPort();

System.out.println(demo.helloWorld());

System.out.println(demo.hi("omkar"));

ProductWSImplService pis = new ProductWSImplServiceLocator();

ProductWS productWS= pis.getProductWSImplPort();

Product p=productWS.find();

System.out.println(p.getId()+"--"+p.getPname()+"--"+p.getCost());

Product p1[] = productWS.findAll();

for(Product p2 : p1){

System.out.println(p2.getId()+"--"+p2.getPname()+"--"+p2.getCost());

}

}

catch (Exception e) {

e.getMessage();

}

}

}

Run the Main(client App) and the result appears on console

This is how we create SOAP based Webservices and clients to consume them
