Hi,

I know this question has been asked a lot of times . But I have tried all of the options and none of them actually work . So please help me .

These are the files ..

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

</filter>

<filter-mapping>

</filter-mapping>
</web-app>

struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
   "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
   "http://struts.apache.org/dtds/struts-2.0.dtd">
   
<struts>
<constant name="struts.devMode" value="true" />

	<package name="Example" namespace="/" extends = "struts-default">
		<action name="getExample" class="com.Struts2Example.action.ExampleAction">
			<result name="success">/doExample.jsp</result>
			<result name="failure">/redoLogin.jsp</result>
		</action>
	</package>
</struts>

ExampleAction.java

package com.Struts2Example.action;

public class ExampleAction 
{

	public String execute()
	{
		
		System.out.println("Came in the execute");
		
		return "success";
	}
}

I cant add the screenshot of the project explorer . Please tell me how I can add that too if needed

Thanks and Regards

Hi ,

I have got the solution . It was buggin me to no end why I was not able to call the action . Then I realized that the action name in the struts.xml was not the same as my action class name .

Thank you
Varun

Hi,

It so happens that , it was not the solution . I somehow managed to get it running again and then something made the Error pop up again . And So the issue is still at large

Help me !

Thanks and Regards

I marked this unresloved. Are you getting the exact same error? I'd be suspicious of how you build and deploy your code. It sounds like you haven't gotten the new struts.xml on the server.
If it is not the exact same error, post your current code and the error message.

Hi,

There is no change in the error .

Thanks and Regards

New struts.xml ? I have a struts.xml which is placed under the src folder . Why would I need a new one . I am a little confused here as to what you intend to point here

I check the location manually and the class file and also the struts.xml is sitting there .

Thank you
