How to create Struts 2 project in Eclipse Galileo ?

Question

I want to create a struts 2 project in eclipse. I have downloaded the latest struts distribution. But things always become confusing when i try to create a struts project in ECLIPSE. Whenever I create a dynamic web project and add struts libraries to that project, some error or the other pops up.

How do I properly setup an eclipse Struts 2 project ?

To get a simple Hello world page, I did:

1. created a dynamic web project (procollab)
2. added struts 2 jars inside WEB-INF/lib
3. added the same libraries inside project build path
4. set the output folder for the src in WEB-INF/classes
5. created a filter in web.xml to send all requests to org.apache.struts2.dispatcher.FilterDispatcher
6. created a struts.xml in src

Errors I get:

Http 404. I get this for any URL, for example http://localhost:8080 or http://localhost:8080/procollab

I have added the project procollab in tomcat server list also in eclipse. but when I access any static resource directly, I get the page. I have the helloworld.jsp in webcontent folder, and when I go to http:localhost:8080/procollab/helloworld.jsp, I get the page correctly.

Have I set up my environment correctly ? Please help

my struts.xml file in WEB-INF/classes

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN"
    "http://struts.apache.org/dtds/struts-2.1.7.dtd"&gt;

<struts>
    <package name="default" namespace="/" extends="struts-default">
        <action name="SayHello">
            <result>/hello.jsp</result>
        </action>

    </package>

</struts>

Http 404. I get this for any URL, for example http://localhost:8080 or http://localhost:8080/procollab

So that's the only problem? Well, a 404 just means that there's no resource on the requested URL. Page Not Found. Simple as that. You need to provide/specify the resource yourself, Eclipse won't do that for you or so. It's the code which you have full in control yourself.

I am not sure what you expect to see at http://localhost:8080, so I'll ignore this part. As to the 404 on http://localhost:8080/procollab, you just need to define a <welcome-file> in the web.xml and ensure that this is available by either (in)directly by a servlet or filter mapping, or a physical file in WebContent. That's all.

If you want to make helloworld.jsp the default landing page, you'll need to add the following to the web.xml:

<welcome-file-list>
    <welcome-file>/helloworld.jsp</welcome-file>
</welcome-file-list>

Update: as per the posted struts config, you thus expect that http://localhost:8080/procollab/SayHello.action is been executed when you access http://localhost:8080/procollab. In this case, you need to configure the <welcome-file> as follows:

<welcome-file-list>
    <welcome-file>/SayHello.action</welcome-file>
</welcome-file-list>
