tomcat 4 mod_webapp config

[VA...@LILLY.COM]

All,

I'm having a little problem with mod_webapp (or maybe I'm not 
understanding this properly).

I have an application deployed in catalina (v. 4b7) called "laserweb" 
(accessible via tomcat's http server port under /laserweb).  I'd like to 
deploy this as the root of a virtual host in apache.  I've configured the 
connector like this within the virutal host:

WebAppConnection myconn warp localhost:8008
WebAppDeploy laserweb myconn /

This doesn't seem to have any affect, as .jsp's, etc. are not being 
processed.  If I pick an URI other than "/", it will work.  (i.e.,

WebAppDeploy laserweb myconn /testuri

works as expected -- the webapp is available via 
http://<myapachevirtualhost>/testuri

Also, does the module have some way of resolving symbolic links?  laserweb 
is symlinked into the $CATALINA_HOME/webapps directory, yet the 
/webapp-info/ page from my virtual host displays the "actual" directory 
location (the target of the link)---I found this a little odd.  How does 
the module know?

My understanding is that using mod_webapp, tomcat virtual hosts don't 
matter.  Is this incorrect?  Can anyone shed some light on this?

Thanks,
Jason

Philippe Richter just sent me a patch about this one... And AFAICS it's a
good one (I didn't try it yet!) but it'll be in the next version of the
module.

I don't know... It's all done in APR... I simply check if that directory
exists or not... Note, the webapp-info should be _really_ disabled on any
propduction server...

Nope, they don't... You can even remove the whole full first part of the
server.xml (you can keep only the Tomcat-Apache engine).
If you need virtualhost support, just configure them in your Apache
httpd.conf, and put your WebAppDeploy lines inside your <VirtualHost> tags.

It's all done automatically (no mod_rewrite, no auto-creation of
configuration files, no nothing)
