Tomcat 4.1 / Apache 2 / JK2 / JNI channel / Win32: Anyone succee d?

["Keim, Markus" <ma...@ordat.com>]

Hello @all,

As the subject says i'm trying to get Tomcat 4.1 connected to
Apache 2 inprocess, using the JNI channel of JK2.

Environment:
Win32 (Windows 2k pro SP3)
JDK 1.4.0_01
Tomcat 4.1.24
Apache 2.0.45
mod_jk2-2.0.43.dll
(jkjni.dll)

I've tried any information and tip i was able to find,
of course http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/,
but apparently there is no way to get Apache and Tomcat connected
inprocess using the suggested propertie files.
I've took all the steps suggested in
http://www.gregoire.org/howto/Apache2_Jk2_TC4.1.x_JSDK1.4.x.html
but with no success, although it seems much more promising as the
above mentioned documentation.
And, last but not least, i've searched this list and found many
threads regarding similar or equal problems, found and tried
several tips and proposals but alas no solution that works for me.

So, i ask myself (and all of you): Is there anybody who has managed
it to get Tomcat 4.1 connected to Apache 2 on Win32 using JK2 with
JNI channel?
If so, i would be glad to see the propertie files and / or hear about
the magic that it takes to make it work.
If not, are there informations i'm still missing, e.g. are there
informations if it's actually possible (i've found an entry in the
Tomcat bug database
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16974that
supposes that it's *not* possible due to a bug in JK2, but it's
discussed controversial).

I've attached the error and log messages from Apache / Tomcat
as well as the propertie files i'm curretly using.

Many thanks in advance for your efforts and
Ciao, Markus
