Yes, you can tell Struts to not use any action extension at all. I'm
doing that right now for a Restful application I developed. I haven't
tried, but you might be able to use wildcards to match the extension
in the action mapping and perhaps use a custom dispatcher result to
determine which actual result should be executed:
<action name="queryName.*" class="com.example.MyAction">
<result type="extDispatch">
<param name="extension">{0}</param>
</result>
</action>
I'd love to see this type of feature either built into Struts or as a
plugin, so if you discover a solution that involves Struts
improvements, please file a JIRA ticket.
Thanks,

Hi Roger (and Al),
Thanks for your replies.
I had thought about doing something like what you specified Roger, by
passing the return type as a parameter. However, in keeping with what seems
to be fairly standard RESTful web service protocol, I was hoping to have the
return type specified after the query name. Then from the users perspective
the URL file type that the request matches the return type, rather than it
just being some random query.
It's true that I could also build the return type into the URL path, but
that would give me several different actions for each query, and I'd like to
have one Action object that knows how to get all of the POJOs that are
associated with the query and then use the results to mux out how to
serialize the POJOs into the correct format (e.g. REST xml, json, rss, etc.)
So is there any way to tell Struts to ignore the extension (*.do or
*.action) and just assume that all requests into the application (or
namespace) are in fact actions it should execute? I'm suspecting not, as
this might block access to other non-action resources, but if there is some
way to set up a * pattern, that might work too.
Thanks for all of your help.
