Welcome Message in Struts 2 running in Google App Engine

Question

I have the following lines below in web.xml

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

But when I access http://localhost:8888 I received the error below:

There is no Action mapped for namespace [/] and action name 
[] associated with context path [].

Isn't it be redirected to index.jsp? How to make welcome file work?

After running server it is searching for an action. You should have an action in struts.xml that mapped to jsp file

Also add following in your web.xml

 <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>

I think you have the welcome file configured properly. The error message looks like a struts error message. It looks like you have a struts configuration problem. Check your action class configuration in your struts.xml file.

it says action name [], it means an empty action name? – JR Galia May 06 '12 at 01:37

Please edit your struts.xml and enter this action as last action (only after all actions as a default action).

<action name="*">
    <result type="redirectAction">
    <param name="actionName">Home.action</param>
    </result>
</action>

Now this must be the last action and it will work like a default action for your application. You application will be redirected to this action if it didn't find any configured action.

Add the below blank action to you struts.xml file in "/" package namespace and it will show the index.html when you will only try to access your url (like appid.app.com) and it will not show the error. Normally it will add a blank action and app engine will redirect the blank action to your welcome file.

    <action name="" class="com.candi.actions.Dashboard" method="noAction">
        <result name="success">index.jsp</result>
    </action>

let explain further. just add blank action by providing blank "" as your action name and redirect your result to index.php which will solve your problem.
