Yes, thanks for the reminder. That's also something I need to keep in
mind, as my installation guide says to load JRE 1.4.2, and I'm using
5.0. But again, I'd like to say that 1.4.2-compiled class files
*should* be able to run on a 5.0 JRE. (I know if you recompile the
source files--which I don't have access to anyway--and have
1.4.2-specific coding such as variables called "enum", that would create
problems.) But I suspect this would be less of a given than having a
5.0.28-able application be able to run on 5.5.20.
Thanks,
Glen

Apart from the changes in suggested deployment strategies and ressourec
definitions there's something to be careful:
Upgrading to TC 5.5 and upgrading from Java 1.4 to Java 5 are two
different things. As long as you do only the first, chances are good,
that you get the webapp to run without code changes.
An upgrade to Java 5 should be tried only after you get the webapp to
run under TC 5.5 with Java 1.4.

Hello,
Question: How common is it for a webapp to be able to run on Tomcat
5.0.28 but *not* 5.5.20?
For the installation of a commerical web application that calls for
installation of Tomcat 5.0.28, I'm inclined to just go ahead and use the
5.5 series of servlet containers. Customer support is concerned that
Tomcat 5.5 will not work (or at least has not been tested on the new
version). My thinking is that:
1.) Both containers implement the same specifications, so their
development team would *really* have to be coding obscurely, bending
over backwards to try to trip up the 5.5 servlet container, to be able
to manage to build a webapp that will run on 5.0.28 but not 5.5.20.
2.) Further, it would require an extremely talented development team to
be able to create a webapp that will run on 5.0.28 but not 5.5.20, but
paradoxically, if they had that level of talent they would *not* build
an application anyway that will work on 5.0.28 but not 5.5.20.
Is my logic here correct or faulty? To what degree is "This webapp will
work on 5.0.28 but not 5.5.20" an old wives' tale?
Thanks,
Glen
