How to deploy JSR181 annotated class in Apache Axis2

JAX-WS (Java API for XML Web Services) provides support for annotating Java classes with metadata to indicate that the Java class is a Web service. With the annotations, you can expose java classes as web services with minimum effort.
Apache Axis2 ships with JAX-WS support since its 1.4 release. This post explains the simplest possible scenario of JAX-WS support, how you can deploy an annotated class in Axis2.

Pre-requisites
Apache Axis2-1.4 or later
JDK1.5 or above

Step 1
Write an annotated class as follows.

package org.apache.axis2;

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

@WebService
public class Calculator {
@WebMethod
public double Add(double x, double y){
return x+y;
}
}

Here, the @WebService annotation tells the server runtime to expose all public methods on the above class as a Web service. Also, with the @WebMethod annotation, you can specifically denotes the methods which are exposed in the web service.

Step 2
Package the above class as a JAR (i.e:- Calculator.jar).
You need to create a directory in Axis2 binary distribution where the annotated jars are placed.
Therefore go to AXIS2_HOME/repository (AXIS2_HOME is where you extracted the binary distro) and create a new directory called, servicejars.

cd AXIS2_HOME/repository
mkdir servicejars

Step 3
Copy the annotated jar file to the servicejars directory. Then, start Axis2server (AXIS2_HOME/bin/axis2server.bat{sh})

Step 4
Go to http://localhost:8080
You will see that the calculator class will be exposed as a web service. Click on the service name.
You will be directed to the following URL and the WSDL of the service can be viewed there.
http://localhost:8080/axis2/services/CalculatorService.CalculatorPort?wsdl

Step 5
Service Deployement is over by now. Lets invoke this service using a client. I will use SOAPUI for the demonstration, you may choose any of the available mechanisms.

Open SOAPUI and start to create a new WSDL project.
Enter the above WSDL path(http://localhost:8080/axis2/services/CalculatorService.CalculatorPort?wsdl) as the initial WSDL.
Select the request, provide inputs and submit. You will get the expected results back.
