Just a thought: are you sure it's the servlet that can't be found? Is
your servlet performing a forward() to a resource that can't be found?
Maybe you're looking for the error in the wrong place.

I'm surprised that this doesn't work as written:

1. The JspServlet is mapped to *.jsp
2. His servlet is mapped to /play/music/includes/venue-listing*
3. url-patterns match the longest-matching pattern, so #2
   ought to override #1

What would be better, probably is:

  /play/music/includes/venue-listing.jsp

...which the OP tried unsuccessfully, earlier. I would have expected
that to work, too. :(

Mapping of exact jsp path to a servlet must work.

That is how precompiled JSP pages are added to a web application: they
are compiled into servlets and servlets are added into web.xml.   See
the jsp-examples webapp in Tomcat 5.5 for an example of such
configuration.


You have to specify the exact path as is. Escaping ('\.') is not
needed and will not work.

Konstantin Kolinko

You don't have to, it's just the path (requestURI), not the query
parameters that the url-pattern refers to.

If you set:

 /play/music/includes/venue-listing

and then request:

 /myAppName/play/music/includes/venue-listing?my=params&what=ever

Then it should work, unless the Servlet itself is rejecting the request
because it's analyzing the path it's called on - which it isn't in
theory because you said it works with:

 /play/music/includes/*


The only possible problem I can think of is that the latter definition
with wildcard is also enabling something that the individual URL doesn't.

No, leave the params in, but omit the .jsp suffix in the URL.

Re: Servlet mapping issue

[laredotornado]

Did you mean to say, call it WITHOUT the params at the end?  If so, when I
did that, everything mapped fine.  However, I do need the query params to
process the page correctly.  Sadly, this url-pattern didn't work


MusicVenueServlet
/play/music/venues/*
   
/play/music/includes/venue-listing*


Note the "*" after "venue-listing" in an attempt to capture any query
params.  Any ideas how to write the url-pattern so that I can catch
additional query params?

Thanks, - Dave

Does the JSP have any includes from the same directory, that might work
when you're using the /* ending, but not when you're using the single JSP?

If you put the mapping back to:

 /play/music/includes/venue-listing

and call it with the params on the end, does it work then?

Servlet mapping issue

[laredotornado]

Hi,

I'm using Tomcat 6.0.26.  I'm having an issue mapping a url-pattern to a
servlet and was wondering if you can see what I'm doing wrong.  In my
WEB-INF/web.xml I have


MusicVenueServlet
/play/music/venues/*
   
/play/music/includes/venue-listing


But visiting the URL

http://mydomain.com/context-path/play/music/includes/venue-listing.jsp?id=3&type=venues

gives a 404.  Oddly, if I change the above to


MusicVenueServlet
/play/music/venues/*
/play/music/includes/*


everything maps fine.  But I don't want to map everything in that directory,
only a single file.  Any ideas?

Thanks - Dave

I think what you need to provide here, is the exact URL that your AJAX
POST is posting to, so that we can have an idea of what the 404 is due to.
Do you know ?

For initial testing, take AJAX out of the picture; just enter the URL for the 
servlet in the browser's address bar and see if you get a response (or use wget 
or curl or equivalent):
http:///APP1/TreeMenuServlet

As others have stated, definitely look in the logs for any problem reporting.

What URL is your AJAX posting to?  Also take a look at your logs for any
relevant messages.  Maybe there was a problem setting up your servlet. 
The servlet mapping looks good as you defined it in your webapp's
WEB-INF/web.xml file.

Re: Servlet mapping issue

[Sergio Arrighi]

Hi!
Thanks for the really quick answer.
It's probabily something really basic to do, but I'm a newbie and I'm 
not able to do it:

I have an application (lets call it APP1) and it's organized like this:

APP1
- WEB-INF
+++ lib
. myJar.jar (contains the package 
org.imin.treemenu)
-.-.-.-.-.-.-.-..-.-.-.-.-.-.-.- myServlet 
(org.imin.treemenu.TreeMenuServlet)

- web.xml

Now I need to register _myServlet_ in the deploy descriptor and I write 
these lines in web.xml:


   
   TreeMenuServlet
   TreeMenuServlet
   org.imin.treemenu.TreeMenuServlet


   TreeMenuServlet
   /TreeMenuServlet


When I try my application and I click on the button which make an AJAX 
post request on this servlet the browser returns an error (404 not found)


Sorry to bother but I'm new!
Thanks

Sergio

Servlet mapping issue

[Sergio Arrighi]

Hello to everyone,

I've developed a tree menu which uses a Servlet and AJAX posts. I've 
exported it as a jar and now I want to include it in another webapp. The 
problem is that this webapp cannot reach the servlet obviously because 
it's not mapped in web.xml.
Here's my question Is it possible to add a servlet mapping which 
points directly to the servlet contained in the .jar file of my tree menu?


Thanks

Sergio
