Apache+Tomcat with mod_jk on OS X

[Matt Raible]

I'm trying to get Apache (1.3.27) integrated with Tomcat (4.1.27) on OS 
X.  I've read the following article (http://tinyurl.com/qkgp), which 
didn't help much, as well as my own (http://raibledesigns.com/tomcat), 
but I've found no success.

I downloaded mod_jk.so (for 1.3.27) from http://tinyurl.com/qkh6. 
Currently, the issue I'm having is with Apache, hopefully someone can 
help.  When I restart Apache, I get:

Invalid command 'JkWorkersFile'

I've heard that folks are using 'webapp' for Apache+Tomcat integration 
on OS X, but I'd rather use mod_jk b/c I'm familiar with it (or jk2).  
Has anyone got either of these working?  Please share your experiences.

Thanks,

Matt
