[S2] Creating and calling a servlet in sturts2 app
hi,
I am having a struts application but due to some reason i want to create a
servlet in this application (which would return a json string) that is going
to be used in JSP (that would map in struts action page url) .. ..
I am unable to create the servlet and call it from that web. I have created
one, added the given servlet entry in web.xml and then tried to call it but
my request has not been dispatched to that servlet.
What should i do ?

there is no error in logs. and yes .. invoking the servlet calls the struts
action. I don't think that servlet configuration has anything to do, since i
created it using eclipse wizard.

Ah, yes. I was thinking that the longest url match would win, but a
filter of course has higher priority than the servlet . So either do
as Andy suggested, or change the url mapping of the filter dispatcher
to something more specific, depending on your needs.

I ran into the same thing as the OP. I think the FilterDispatcher is catching all requests to the servlet since it uses a url-mapping of /*.
The Struts in Action book, from what I remember, suggests having an Action receive the request and then dispatch to a servlet.
If anyone has direct experience with this please let us know.

I'm not sure I follow you. Are you saying that when you try to invoke
the servlet, the struts action is invoked instead? Or is nothing
invoked? And again, have you checked your logs for errors or any
traces of what's happening? Maybe your servlet is not correctly
configured so it's not started?

This is the entry that i made in web.xml for the servlet

even if i try to call the servlet directly (direct writing the url in the
address bar) there is no call going to servlet, rather the struts action is
being called. here is the mapping for that stuts action

no matter if i call servlet directly or indirectly, my call never reaches to
the servlet. how can i do this?

You could start by providing some more information. How do call the
servlet, and how is it configured? Do you get any errors in your log
files? Can you invoke the servlet by typing it's url in the browser?
