I had Apache and tomcat working together fine on a server I was configuring on my home network.

When I took the server to a co-location site to replace the server I had there I lost the connection. Apache can't find content via the worker.

It must be a network configuration thing but where?

What do the logs say?

From apache error log when trying to access a jsp on tomcat via apache:

says what?

grep -i jk httpd.conf

LoadModule jk_module /usr/local/apache2/modules/mod_jk.so
JkWorkersFile /usr/local/apache2/conf/workers.properties
JkMount /mld/* worker1
JkMount /ngs worker1
JkMount /ngs/* worker1
JkMount /twilight worker1
JkMount /twilight/* worker1

any of these remote hosts/mounts?

What apache and tomcat versions?

Apache/2.4.7

apache-tomcat-7.0.50

No remote hosts/mounts, all local

I turn mod_jk logging to debug. After trying to access a jsp from tomcat via apache I got this on the mod_jk log:

[Sun Aug 24 09:40:49 2014] [4052:3050306368] [debug] jk_translate::mod_jk.c (3623): missing uri map for reportscores.com:/twilight/index.jsp

I have virtual hosts and set "JkMountCopy On" on httpd_conf
html for the virtual hosts home page is coming thru

Problem solved, I put the JKmounts in the virtual hosts

Glad it worked out.
