Hello,
During last 2 years I've created couple of Cocoon-based sites.
They have been running on Tomcat 4.1.31, J2SDK 1.4.2.

I've been using the latest version of Cocoon for each site,
that's how I have here 2.0.3, 2.1, 2.1.5, 2.1.6, 2.1.7, etc.

This is a damn mess :/
Compilers: javac, jikes, pizza, eclipce
Transformers: xslt, xalan, xsltc
cache (stores): ...., ......, ..... (you know what I'm taking about)

That one is good, the other is bad, then the other is good
again, and so on. Ever if everything by accident happens
to work with no errors and crashes, tuning that up for
performance is a real horror.

In addition to that, I'm already fed up with Tomcat 4.1 and
Java 1.4. This is probably an issue of poor garbage collector,
but in real life, there is NO CHANE to have _one_single_day
without a appserver crash, usually because of OutOfMemory error.
(and it's not a matter of phisical memory!)

I want to try Tomcat 5.5.12 on JDK 1.5.0 now.
A lot of coding has been done to Tomcat,
and probably also Sun JVM is more stable now.

I just want to run Cocoon webapps built with JSDK 1.4 on JDK 1.5.
What I've already learned:
- Cocoon 2.1 with xalan - works.
- Cocoon 2.1.7 with xalan - doesn't.
- Cocoon 2.1.7 with xsltc - works. Till you have multiply variables :/

My questions is: If I upgrade all cocoon webapps to 2.1.7 or 2.1.8,
what components / versions shell I use to get stability and performance?
Please recommend at least:
a) compiler
b) parser
c) transformer
d) stores
Are these recommened for JDK 1.5 components default in Cocoon 2.1.8.?
