JAX-WS

JAX-WS

Hello Friends i hope you all are aware of web -services.i am going to demonstrate you simple example of soap web service using glashfish server. before going into details of JAX-ws you need to have understanding of wsdl docuement.when client sends Request it will be soap request & soap response will be returned by container.however in case of Glashfish ,it autogenerates wsdl document.

i personally advice you to go through elements of wsdl document  prior to going into the JAX-WS. some of the elements of WSDL document are <definations>,<operation>,<service>,<porttype>,<binding>,<type> etc.

If i want to make web service than i will simply mark class as @WebService. by default all methods defined in the class will be  exposed as web methods.for detail understanding of JAX-WS go to http://oak.cs.ucla.edu/cs144/reference/WSDL/

i am going to demonstrate you product Catalog Web Service.

Sample Code:
//Model Data
package org.demo.model;

public class Product
{
    private String name;
    private String sku;
    private double price;
   
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getSku() {
        return sku;
    }

    public void setSku(String sku) {
        this.sku = sku;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

   
    public Product() { }
   
    public Product(String name,String sku,double price)
    {
        this.name=name;
        this.sku=sku;
        this.price=price;
       
    }
   
   

}

//Service Implementation consisting of bussiness logic

package org.demo.bussiness;

import java.util.*;

import javax.jws.WebMethod;

public class ProductServiceImpl
{
   
    List<String> booklist =new ArrayList<>();
    List<String> musiclist=new ArrayList<>();
    List<String> movielist= new ArrayList<>();

    public ProductServiceImpl()
    {
    booklist.add("Inferno");
    booklist.add("Joyland");
    booklist.add("The Game Of Thrones");

    musiclist.add("Random Access Memories");
    musiclist.add("Night Visions");
    musiclist.add("Unorthodox Jukebox");

    movielist.add("Oz the Great and Powerful");
    movielist.add("Despicable Me");
    movielist.add("Star Trek Into Darkness");
    }
   
    public List<String> getProductCategories()
    {
        List<String> categories = new ArrayList<>();
       
        categories.add("book list");
        categories.add("Music list");
        categories.add("Movie list");
       
        return categories;
       
       
    }
    public List<String> getProducts(String catname)
    {
        switch (catname.toLowerCase()) {
        case "books":
            return booklist;
        case "music":
            return musiclist;
        case "movies":
            return movielist;
        }
        return null;
    }
   
    public boolean addproduct(String  category,String product)
    {
        switch (category.toLowerCase()) {
        case "books":
            booklist.add(product);
            break;
        case "music":
            musiclist.add(product);
            break;
        case "movies":
            movielist.add(product);
            break;
        default:
            return false;
        }
        return true;
       
       
    }

Run it on Glashfish you can find tester link as well in order to test functionality of web service.
