Here's the code - enjoy. I wrote a different one for PathRequestFilter
(i.e. /do/*), but this one should work for both - my local versions have a
lot of extra logic in it - so I trimmed that. This is untested and I don't
even know if it'll compile. I'll be adding to my appfuse project shortly,
so I'll know in the next week or two.
Here's the settings in web.xml:
<filter>
<filter-name>requestFilter</filter-name>
<display-name>Request Filter</display-name>
<filter-class>org.appfuse.webapp.filter.ExtensionRequestFilter</filter-class
>
<init-param>
<param-name>allowedExtensions</param-name>
<param-value>.html,.asp,.cfm</param-value>
</init-param>
<init-param>
<param-name>ignorePaths</param-name>
<param-value>/images,/includes</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>requestFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

Hello Matt!
That sounds good.
But can you give full code examples (web.xml, other necessary codes)? I
do not know, how to realize it.

Yes this is possible. I use a filter mapped to /* and perform logic to
lookup all the actions and attempt a match, then forward to the action
if
it's found.

Subject: Change the ".do" extension
Hello!
Is there a possibility to get rid of the .do extension in the actions?
For example:
http://localhost/login.do
should be
--> http://localhost/login
Ist this possible?
Thanks!
Dirk
