Ive just rebuilt mod_jk with --enable-jni according to http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html
and configured the connector and workers.proerties according to http://www.howtoforge.com/apache2_tomcat5_mod_jk_p3 Can I implement this new Multithreaded mod_jk.so with Apache 2.x or should I always use the prefork MPM ?
