Struts provides the option to configure values in properties file and use them in struts framework using the Message-resources element in struts-config.xml
Creating the Action Class
package org.mybusiness.strutstutorial.actions; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.struts.action.Action; import org.apache.struts.action.ActionForm; import org.apache.struts.action.ActionForward; import org.apache.struts.action.ActionMapping; public class HelloWorldAction extends Action { @Override public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) { System.out.println("HelloWorld Action Invoked"); return mapping.findForward("HelloWorld"); } }
Adding configurations to struts-config.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd"> <struts-config> <!-- Using Global Forwards to forward to the desired view for Home Page --> <global-forwards> <forward name="HelloWorld" path="/WEB-INF/jsp/HelloWorld.jsp" /> </global-forwards> <!-- Contains the URL Mapping --> <action-mappings> <action path="/helloworld" type="org.mybusiness.strutstutorial.actions.HelloWorldAction" /> </action-mappings> <message-resources parameter="application" /> </struts-config>
/WEB-INF/jsp/HelloWorld.jsp
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Hello World</title> </head> <body bgcolor="#ffe"> <h2>Hello World. Welcome to my Struts based web application</h2> </body> </html>
With the above configurations deploy your web application or start the application using Eclipse WTP plugin and access the URL http://localhost:8080/StrutsTutorial/helloworld.do
