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;
}
}
//End Point Interface which client will able to see
package org.demo.nisarg;
import javax.jws.WebMethod;
import javax.jws.WebResult;
import javax.jws.WebService;
import java.util.*;
@WebService(name="TestmartCatalog" ,targetNamespace="nisargpathak.blogspot.in")
public interface ProductCatalogInterface
{
@WebMethod(action="fetch_categories", operationName="fetchCategories")
public List<String> getProductCategories();
@WebMethod
public List<String> getProducts(String productname);
@WebMethod
public boolean addproduct(String productname,String category);
@WebMethod
public List<String> getProductv2(String productname);
}
//Service First Approach
package org.demo.nisarg;
import java.util.List;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
import org.demo.bussiness.ProductServiceImpl;
@WebService(endpointInterface="org.demo.nisarg.ProductCatalogInterface", portName="TestMartCatalogPort", serviceName="TestMartCatalogService")
public class ProductCatalog implements ProductCatalogInterface
{
ProductServiceImpl product= new ProductServiceImpl();
@Override
@WebMethod
public List<String> getProductCategories()
{
return product.getProductCategories();
}
@Override
@WebMethod
public List<String> getProducts(@WebParam(partName="pName")String productname)
{
// TODO Auto-generated method stub
return product.getProducts(productname);
}
@Override
@WebMethod
public boolean addproduct(@WebParam(partName="Product-Name")String productname, @WebParam(partName="Category")String category)
{
// TODO Auto-generated method stub
return product.addproduct(productname, category);
}
@Override
@WebMethod
public List<String> getProductv2(String productname)
{
// TODO Auto-generated method stub
return product.getProducts(productname);
}
}
WSDL Document :

Run it on Glashfish you can find tester link as well in order to test functionality of web service.
Thanks
for any query Regarding post ping me on pathak.nisarg@yahoo.com
