Re: ApJServAction replacement in Tomcat?

[Andy <ac...@yahoo.com>]

Sorry,  ApJservAction appears to be some sort of framework for
handlers for different extensioned files.  Sorta what the JSP runner
is for jsp's.  They created their own tag library..  I want to move away
from it and go to standard stuff.  Especially since they still have just
about as many servlets as they have their-answer-to-jsp-files.

I believe mod_jserv is suppose to continue to be supported with 3.2.
I'm thinking I might have to stick with it for the moment...though
lamentfully.  I wish there were a better set of documentation clearly
explaining the transition from mod_jserv and tomcat 3.1 (the nuances
that change each time).  I searched like mad for this ApJservAction stuff.
