Calling ActionClass in tiles.xml using Struts 2.0

I reviewed the example of tiles with struts2.0 and found that in tiles.xml jsp pages are called like:

<definition name="welcome" extends="baseLayout">
  <put-attribute name="title"  value="Welcome"/>
  <put-attribute name="body"   value="/welcome.jsp"/>

BUT my question is if I want to call the action class instead of .jsp pages than how to call it like

<definition name="friends" extends="baseLayout">
  <put-attribute name="title"  value="Friends"/>
  <put-attribute name="body"   value="/checkActionLink.action"/>

when I am trying to write to execute the above code than its showing the error that checkActionLink.action is not found....thanks in advance for the help.....

Following is the web.xml file

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </filter-mapping>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

Solution

After so much research I found out that adding the following tag: <dispatcher>FORWARD</dispatcher> in the web.xml the issue gets resolved.

Now the question arises why? As per my understanding when we add any action as the value of value attribute of the <put-attribute/> tag the request is forwarded to the mentioned action so the action is executed successfully.

Previously <dispatcher>FORWARD</dispatcher> tag was missing so this issue was caused.

I would really appreciate if any correction is there in my understanding.

Thanks. Happy Coding :).
