Subject Re: Servlets works fine, JSP's don't

Hello awarnier, thank you very much for your detailed response:

1) I'm accessing Tomcat via http://machine_ip/ so, its through apache.

2) At the bottom of the error pages (the 500 Internal Server Error), the
following can be found:
Apache/2.2.3 (Debian) mod_jk/1.2.27 Server at Port 80

3) I've had a look at both apache2 & tomcat logs, and it just throws nothing
after I reproduce the error. Catalina is set on debug mode, and I having a
look at it, I only find DEBUG entries, not ERROR ones.  Do you know if there
is a way to increase verboseness on the errors shown on the browser to debug
that error 500 a little more?

I'm using tomcat apache-tomcat-5.5.17 & apache2 2.2.3-4+etch6. The mod_jk
connector is the latest version download from the official website.

4) I'm affraid I can't connect to tomcat via 8080, since we'r all
firewalled. Anyways, I assume its working correctly since its redirecting
data to port 80, and its displaying fine. Guess mod_jk conector is working
as intended.

Thanks a lot for your time awarnier.
