It’s the simplest possible Web Service (that I’m aware of) you can make. I will not explain the details, only the steps.

1. Download AXIS2, unzip, and start it by executing: bin/axis2server.sh;
2. Create the following folder structure “helloservice/META-INF”;
3. Create the file “helloservice/HelloService.java” and place inside the folling code:public class HelloService
   {
       public String sayHello(){
           return “Hello World!!!”;
       }
   }
4. Compile the class by calling “javac HelloService.java”;
5. Create the file “helloservice/META-INF/services.xml” and place inside the folling code:
   <service>
       <parameter name=”ServiceClass” locked=”false”>HelloService</parameter>
          <operation name=”sayHello”>
          <messageReceiver class=”org.apache.axis2.rpc.receivers.RPCMessageReceiver”/>
       </operation>
   </service>
6. Move/copy the folder “helloservice” to inside the Axis2 folder “[AXIS_HOME]/repository/services”;
7. Axis2 will deploy it giving the message “Deploying Web service: helloservice”
8. Try it by requesting the url: http://localhost:8080/axis2/services/helloservice?wsdl or just http://localhost:8080/axis2/services/helloservice;
