Getting Servlets and Struts 2.1.6 to work together?
I'm trying to upgrade from Struts 2.0.11 to 2.1.6 and having a problem, struts isn't passing requests thru to my servlets.
I have a servlet named 'status' and defined in web.xml like this.
<servlet-mapping>
<servlet-name>StatusServlet</servlet-name>
<url-pattern>/status</url-pattern>
</servlet-mapping>
After upgrading to 2.1.6 I now get the following exception when I try to go the the status servlet. I'm not (intentionally) using conventions or any other zero config-ish plugin. It's looking for an action named 'status' which I don't have. I use a '.action' suffix for all my action URL requests.
2009-03-03 13:41:05,692 WARN org.apache.struts2.dispatcher.Dispatcher:49 - Could not find action or result

So how do I get it to behave like 2.0.11 and pass any requests that don't have .action suffix thru to the servlets?

I'm not quite sure why this happens here instead of in the Convention
plugin (or maybe it happens both places?) but I'm not convinced the
default setting is the correct place.

That recommendation still stands, AFAIK: most people probably aren't
running mixed systems, and unless they're paying enough attention to
realize that S2 relies on serving its own CSS/JavaScript/etc. via the
filter, they shouldn't change the mapping.

I spent some time in the debugger and found out what 'really' changed was
the default action extensions (struts.action.extension) changed from just
'action' to 'action' plus "" (no extension). This was causing my "/status"
request with no extension to be treated as an action.
The old (2.0.11) struts default.properties had:
struts.action.extension=action
The new (2.1.6) has:
struts.action.extension=action,,
If I explicitly set the extension back to just 'action' then It works like
it used to and the request goes thru to my servlet.
In my struts.xml I added: <constant name="struts.action.extension"
value="action" />
So I still have the question of what is the 'correct' filter mapping for the
struts filter?
I found the FilterDispatcher javadocs which says:
"IMPORTANT: this filter must be mapped to all requests. Unless you know
exactly what you are doing, always map to this URL pattern: /* "
I also see that FilterDispatcher has been deprecated, a note in the upgrade
guide would have been nice :). (I'm going to add what I've found to the
wiki so will include a note.)

Why do you recommend mapping '/struts/*' to the struts filter? What uses
this convention?
Clearly there has been a change in behavior between 2.0.11 and 2.1.6, I'm
wondering if this was intentional? Does the FilterDispatcher now assume
that ever request it sees must be an action? If so this kind of feels wrong
for a Filter, I expect filters to handle what they need to and pass
everything else through to the next layer.

I noticed today as well that struts was picking up an action I had defined,
even though I had no .action. I think I had seen it before intermittently, but
wasn't able to nail it down. Truthfully, I've been using conventions so long
that it strike me as odd at first. It was only because I was explicitly trying
to take it out of the equation for something I was working on that I noticed.

Is this what you mean?
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
I previously had it as <url-pattern>/*</url-pattern> based on all the books
and examples I was able to find. So is there no reason to include everything
in the filter?

You probably want to edit the url pattern of the struts 2 filter mapping.
