In previous post JAX-WS Tutorial we discussed about how to create web service using JAX-WS API and create a Simple SEI(Service Endpoint) and publish that service end point using simple java program on existing running web application, Now i am going to discussed with you,"How to integrate JAX-WS enabled service with your simple web application".
Often times, JAX-WS always be part of your Java web application. Here i show you how to integrate JAX-WS into Java web application easily,only some basic step which are as follows.
1:-Directory structure of your web application
2:-create a simple Endpoint
package com.amit.ws;
import javax.jws.WebMethod;
import javax.jws.WebService;
@WebService
public class HelloWorld{
@WebMethod(operationName="getHelloWorld")
public String getHelloWorld(String name) {
return "Hello World JAX-WS " + name;
}
} 3:-create we service deployment descriptor(sun-jaxws.xml) in your WEB-INF folder
<?xml version="1.0" encoding="UTF-8"?>
<endpoints
xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime"
version="2.0">
<endpoint
name="HelloWorldWs"
implementation="com.amit.ws.HelloWorld"
url-pattern="/hello"/>
</endpoints> 4:-Make following entries on your web.xml file 1:-Defines “com.sun.xml.ws.transport.http.servlet.WSServletContextListener” as listener class.
2:-Defines “com.sun.xml.ws.transport.http.servlet.WSServlet here is content of web.xml file,
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name>Archetype Created Web Application</display-name>
<listener>
<listener-class>
com.sun.xml.ws.transport.http.servlet. WSServletContextListener
</listener-class>
</listener>
<servlet>
<servlet-name>hello</servlet-name>
<servlet-class>
com.sun.xml.ws.transport.http.servlet.WSServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
</web-app> 5:-Done The integration between JAX-WS and web application is done. Deploy it and access via URL : http://localhost:8080/WebServicesExample/hello here is the output look like this on your web browser,
Endpoint Information
Service Name: {http://ws.amit.com/}HelloWorldImplService
Port Name: {http://ws.amit.com/}HelloWorldImplPort
Address: http://localhost:8090/HelloWorld-20110808/hello
WSDL: http://localhost:8090/HelloWorld-20110808/hello?wsdl
Implementation class: com.amit.ws.HelloWorldImpl
And when you click on http://localhost:8090/HelloWorld-20110808/hello?wsdl (wsdl uri) it will show you wsdl generated xml,here it is the generated wsdl code.
This XML file does not appear to have any style information associated with it. The document tree is shown below.
