Will do. The most obvious thing that springs to mind is that the
config files don't look anything like the declarative xml that is used
when configuring other enterprise java components (I'm thinking of
web.xml, ejb-jar.xml, etc) or the pseudo-xml of httpd.conf. Since an
XML parser is included "for free" with JDK1.4, and tomcat can
obviously parse XML even without this (web.xml again) how hard would
it be to implement?

The format of the workers2.ini file is even more perplexing: it
doesn't look anything like a "normal" java properties file; more like
a windows INI file than anything else. It just doesn't "chime" with
the experience of your average admin or java developer, ime.

It sounds like an interesting thing to do, but won't this hamper
portability? It's nice to be able to take the jk2.properties and
workers2.properties and put them in the right place on any platform.

I'll try and be constructive. Thanks for being so open.
