Don't worry, I never said I'll modify mod_jk to use APR, and I 
didn't remember Dan speak about it. We're correcting the remaining

+1 and you know I use Tomcat in production and the current mod_jk 
works well for me on Linux Boxes. 

Let's be pragmatic. mod_jk works on many Unix systems, Windows and 
Netware. The most important build feature to add is the configure 
(autoconf) stuff to help build mod_jk on many more targets. 
We even can take a look at APR configure which detect the various envs. 

There was a confusion on mod_jk, mod_webapp and APR.

Now only mod_jk let you connect Tomcat to Apache (1.3/2.0), IIS or NES. 

I really feel that mod_jk will be the reference connector for many
months. it use a network protocol, ajp13, which works well even if
the protocol could be improved. 

I allready speak about that improvement (ajp13++ or ajp14). In that
case a new protocol will be added but the core of mod_jk will stay the
same. mod_jk works well now with ajp12, ajp13 why not an ajp14 which
features like strongest ACL (connect time), forward load/unload of 
context/webapp to Apache web server, better recovery in updload mode....

Pier you need to make more reports on mod_webapp if you want others 
people involved into that project. For example, the switch to APR 
was not discussed on the list.

You may read the various discussions between I and Dan about mod_jk
and everybody known what we're doing.
