including the output of an action execution in a servlet response.

Hi all,

I have a servlet that I want to include the result of a struts2 action 
in the
response. I have a method that's called from my servlet's doGet method,
which does something along the lines of

        .....
        RequestDispatcher requestDisp = 
getServletContext().getRequestDispatcher("/somepackage/ExampleAction.action");
        requestDisp.include(request, response);
        .....


When I invoke the action directly from the browser (i.e. 
http://myhost/somePackage/ExampleAction.action ), it works
just fine.  When trying to invoke the action out of the servlet with 
RequestDispatcher.include(), I get a message in
the response where the output should be that reads

"The requested resource (/somePackage/ExampleAction.action) is not 
available".

I can't find what's generating this message, and it's not clear to me 
why my action isn't being invoked.
I'm fairly certain I'm doing something stupid, but it's not obvious to 
me yet.  Any ideas?

thanks in advance,

- Darren.

I finally found the answer for any that are interested.  servlet filters 
apparently don't
trigger (by default) on forwarded and included requests.  I had to 
change my filter url
mapping in web.xml to make the struts2 filter fire....

from:

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

to:

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
        <dispatcher>INCLUDE</dispatcher>
    </filter-mapping>


cheers,

- darren.
