[Amey Ambulgekar]

Hello Java friends,

I am beginner to struts2 and yesterday i did a simple Hello World Program but I got an error .

Here is my program and my exceptions .

Struts.xml file ::

<?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>

<package name="default" extends="struts-default" namespace="/">
<action name="getTut" class="org.com.struts.TutAction">
<result name="success">/success.jsp</result>
<result name="failure">/error.jsp</result>
</action>
</package>

</struts>

here is my 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">
<display-name>Struts2App</display-name>

<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

</web-app>

and here is my java class ::

package org.com.struts;

public class TutAction {
public String execute(){
System.out.println("Hello.! from struts");
return "success";
}
}

and now what i did run an application and i appended at the end
http://localhost:8080/Struts2App/getTut.action //<--

but i got this error ::

HTTP Status 404 - There is no Action mapped for action name getTut.action/.
type Status report
message There is no Action mapped for action name getTut.action/.
description The requested resource (There is no Action mapped for action name getTut.action/.) is not available.
Apache Tomcat/6.0.35

Use this when you are posting code

Post your project Structure.

install and uninstall tomcat6 5-6 times.

You are doing something wrong why you are screwing tomcat. :P
