I cannot access anything from my Apache2 web server - I can't load the
home page, groupwise, anything like that.

I've looked in the error logs in the Apache2 directory - in
the "mod_jk.log" file I am finding this line:

[Wed Nov 22 14:43:21 2006] [error] jk_ajp_common.c (1758): Error
connecting to tomcat. Tomcat is probably not started or is listening on
the wrong port. worker=ajp13 failed

I had this server up with a different IP Address, and recently changed it -
the web server stopped working at this point... any suggestions on
something I may have missed in the config.
