Linking/forwarding GET requests using Default servlet or other Tomcat feature

2005-07-27 Thread Rob Hunt
I'm running a stand-alone (no Apache front-end) TC 5.0.19 server on a WinXP 
box.  I have a webapp that has a /teams directory that contains gameScores.htm, 
teamStandings.htm and scoreForm.htm.  I also have a /playoffs directory (can 
you tell this is a sports-related site?) directory that has the **exact same 
files**.  

Now, I'd like to keep a single copy of the 3 files in one directory and have 
some servlet-mappings  in web.xml that would forward the request from 
/playoffs to /teams **WITHOUT** the HTTP client being aware of a 'redirect.'  
That is, I don't want to issue an HTTP redirect, and WinXP doesn't have file 
linking like Unix.  Is there some hook in the Default servlet (or other 
TC-supplied class) that would allow one to do something like the following:

  servlet
servlet-nameplayoffs/servlet-name
servlet-class...DefaultServlet (or whatever)/servlet-class
init-param
  param-nameFORWARD/param-name
  param-value/teams/param-value
/init-param
  /servlet
  servlet-mapping
servlet-nameplayoffs/servlet-name
url-pattern/playoffs/*/url-pattern
  /servlet-mapping


The idea is I'm being very lazy and hoping that there is a feature in the 
default servlet (or other TC-supplied filter/class) that will allow this 
without me having to write same.  (Of, if someone has some code they'd like to 
share...)

Thanks.

The servlet-entry in web.xml can take a jsp-page parameter instead of a 
servlet-class
If you define your JSP as a servlet, you can create as many mappings to it as 
you like.

jsp-file that is.

Yes, I know you can make many mappings to a given servlet/jsp, but that's not 
what I'm asking for.

When an HTTP client requests /playoffs/gameScores.htm, I'm hoping there's some 
slight-of-hand trick/feature that will cause Tomcat to serve 
/teams/gameScores.htm WITHOUT a redirect so that it appears to the client that 
they're getting /playoffs/gameScores.htm.

Sounds like something that can be done with frames or iframes

Look up the RequestDispatcher:
http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/RequestDispatcher.html

Server side forwards don't use a redirect

Yes, I know that an internal forward would work.  I just didn't want to 
code/test/debug it.  Yes, I'm being very lazy here; but I hate to reinvent the 
feature if it already exists and it just seems to me that this is something 
that probably should already exist (since it can be done in Apache).

2005-07-27 Thread Tim Funk
There is nothing in tomcat which out of the box can do this. But there are 
many 3rd party filters (or 3 liners which are easy to write) which can do this.
