Problems with Mod JK (Apache 2.052 and Tomcat 5.5.9)

[Luka Andrejasic]

Hello guys,

I am trying to figure this one out for weeks. Nothing seems to work and I am 
running out of ideas. The problem seems to be with Mod JK, as Apache and Tomcat 
work without problems on their own.

Below are all the main configuration files, as well as the error log (at the 
bottom) :

// System Configuration :

- OS : RedHat Linux ES 4.0 (2.6.9-22.0.1)
- Apache : 2.0.52
- Tomcat : 5.5.9
- MySQL : 4.1.12
- Mod JK : 1.2.15




// Mod JK Installation :

   tar -xzf jakarta-tomcat-connectors-jk-1.2.15-src.tar.gz
   cd jakarta-tomcat-connectors-jk-1.2.15-src
   cd jk
   cd native
   ./buildconf.sh
   ./configure --enable-EAPI --with-apxs=/usr/sbin/apxs
   make
   make install

   cp ./apache-2.0/mod_jk.so /etc/httpd/modules
