intercept and redirect to war file of my choosing(based on URL)

[Dean Hiller <de...@xsoftware.biz>]

I have a url of this format http://<machine>/<variable>/<warfilename>

Where no matter what <variable> is equal to, I would like to be able to
direct the to tomcat/webapps/<warfilename>.war servlet.  I have been trying
to do this with a valve on the engine hoping I could modify the request URL
before the tomcat engine decided which war  file would service the request.
Is this even possible?  I tried this with a generic filter and a forward but
that failed and tomcat said http://machine/<warfilename> resource does not
exist when using the above url.  If I use http://<machine>/<warfilename>, it
works fine and the resource exists when using a filter I deployed to
common/lib.

Below is the code I tried to use for that valve(since I could not get the
filter to work) in the engine to modify the request so that the url would be
http://<machine>/<warfilename> and I was planning on sticking <variable> in
as a request attribute or something so the war file could access it.  Any
ideas?

thanks,
dean
