QueueMetrics installation / Ubuntu+Tomcat6 Installation Problem

« on: April 08, 2010, 16:44:45 »

Hello, I am a novice in Tomcat, never tried before. I am trying to configure Queuemetrics on my Ubuntu Linux machine (AMD64). I installed Tomcat using "apt-get install tomcat6". Followed all the steps on http://www.astrecipes.net/index.php?n=108

I get the following error(s) on trying to access Queuemetrics:


HTTP Status 500 -
