Problem with mod_jk 1.2 - 500 Internal Server Error

[Pat Maddox]

I'm using JBoss 4.0.1 with integrated Tomcat 5, and I'm trying to
connect it to Apache 2. Whenever I make a request to a resource that
should be passed along to Tomcat, I get a 500 Internal Server error.
Looking at the mod_jk.log shows:

[Thu Jan 13 13:45:34 2005] [jk_uri_worker_map.c (445)]: Into
jk_uri_worker_map_t::map_uri_to_worker

[Thu Jan 13 13:45:34 2005] [jk_uri_worker_map.c (445)]: Into
jk_uri_worker_map_t::map_uri_to_worker



So it looks like it maps to the correct worker, but then can't find the
worker. I've got no clue why this is happening.

Here's my workers.properties file:

# Define worker
workers.list=default
worker.default.port=8009
worker.default.host=localhost
worker.default.type=ajp13


And here's the section of httpd.conf where it's all set up
#
# mod_jk settings
#
JkWorkersFile "conf/workers.properties"
JkLogfile "logs/mod_jk.log"

JkLogLevel debug

JkMount /*.jsp default
JkMount /*.do default
JkMount /status default

# End of mod_jk settings


I'm really confused and frustrated with this...I'd appreciate any help.

Thanks, Pat

Can you resolve the 'localhost'?
See if you have localhost inside etc/hosts
or use 127.0.0.1 for host name.

Also, you can provide the mod_jk version used (1.2.8, etc.)

Well, I managed to get it. And I feel unbelievably stupid (as is the
case with most problems). The simple fix is
worker.list=default
rather than
workers.list=default
