 Package com.struts.action; Import Com.opensymphony.xwork2.ActionSupport;  Public class extends actionsupport {        //  processing request public        throws  Exception {            System.out.println ("Access to Action, processing request");            System.out.println ("Call service");             return "Success";        }}

Fourth Step configuration Struts.xml file is placed under SRC

<?XML version= "1.0" encoding= "UTF-8"?><!DOCTYPE struts Public "-//apache software foundation//dtd struts Configuration 2.0//en" "Http://stru Ts.apache.org/dtds/struts-2.0.dtd "><Struts>    < Packagename= "xxxx"extends= "Struts-default">        <Actionname= "Hello"class= "Com.struts.action.helloaction"Method= "Execute">            <resultname= "Success">/myjsp.jsp</result>        </Action>    </ Package> </Struts>
