Coincidentally, I've been working on this same issue. I needed struts actions to handle PDFs.

My solution was to add pdf to the action extensions, as in:

<constant name="struts.action.extension" value="pdf," />

Note the critical trailing comma which allows for blank extensions in addition to pdf. I'm not sure exactly how struts, by default, knows to ignore anything with an extension. Mostly this is a good thing, as it allows you to serve images, static resources, etc., without going through struts.

There's this interesting comment in the default.properties file inside the struts core jar:

### The blank extension allows you to match directory listings as well as pure action names
### without interfering with static resources.
struts.action.extension=action,,

Sounds like what you need is to handle ALL urls, with any possible extension? I don't know how to do that, but I bet there's a way. Of course this would mean that you would have to handle all static resources through struts which could be painful. But maybe you don't have any.

Thanks,

Fred

I configured struts to handle url mapping with no extensions this way

<constant name="struts.action.extension" value=",," />

With this action mapping
         <action name="*" class="myAction" method="myMethod">
                 <param name="myId">{1}</param>
             <result type="tiles">myTile</result>
         </action>

I can handle urls like:

/aaa/bbb/ccc
/aaa/bbb/ddd
/aaa/bbb/eee

But i wish to handle this kind of urls too:

/aaa/bbb/fff.xyz
/aaa/bbb/fff.jkw
/aaa/bbb/fff.anykindofextension

But when i insert a DOT in the action name (mapped by a wildcard) I
get a 404 error.


Any idea?

Thank you
