[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - Re: How to enable logging on Tomcat

[bredknap]

Hey Peter,

Thanks for the reply.

Below is the type of exception message I get when this problem occurs.  At the bottom of the message it says 'note The full stack trace of the root cause is available in the Apache Tomcat/5.5 logs.'  These are the logs I'm trying to enable/view.  How do I do this?  Can these logs be filtered to include my application?  Do you have any other suggestions on where I can look for the cause to this problem?


TIA,

Brian
