Webservice example, using only JAX-WS (without CXF). Comments describe what else to do in the deploy conguration.

BasicService.java

/*
 * Use wsgen to generate web service artifacts
 * ===========================================

Start a command prompt and navigate to the root of the project directory. Make sure the JDK is in your PATH, 
or else you can't execute the wsgen command. Create a wsdl directory in WebContent/WEB-INF/ or else wsgen will complain. 
Use the wsgen command to generate the artifacts like this:

wsgen -classpath build/classes/ -wsdl
      -r WebContent/WEB-INF/wsdl -s src
      -d build/classes/ com.hcllearning.webservice.BasicService

This command will generate the source, class files, and WSDL file for the web service implemented as 
com.javaeenotes.ExampleWS. When wsgen complains about not finding the class, you have to build the project first. 
When the command is successful, you can refresh the project and you'll find the artifacts in your project tree.

The generated WSDL-file needs some editting, before you can use it. Open the WSDL-file and search for 
REPLACE_WITH_ACTUAL_URL. Replace this string with the web service URL: http://127.0.0.1:8080/webservice/ExampleWSService, 
and save the file.

Add the following to web.xml
============================

  <listener>
		<listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>
	</listener>
	<servlet>
		<servlet-name>basicService</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>basicService</servlet-name>
		<url-pattern>/services/BasicService</url-pattern>
	</servlet-mapping>


Create a file sun-jaxws.xml aside web.xml:
==========================================

<?xml version="1.0" encoding="UTF-8"?>
<endpoints
  xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime"
  version="2.0">
   
  <endpoint
      name="BasicService"
      implementation="com.hcllearning.webservice.BasicService"
      url-pattern="/services/BasicService"/>
       
</endpoints>


Add those files to  the classpath (Jax-WS - http://jax-ws.java.net/):
=====================================================================

ha-api.jar
jaxb-impl.jar
jaxws-api.jar
