Newbie Q: How to get a Servlet workiing?

[Vivienne]

Hi, I recently got Tomcat 3.2.1 running (standalone) on my Redhat 6.1 machine.   I got it installed in /usr/local/tomcat and has changed nothing.   Supposed I got a servlet class, say abc.class then where should I put this file and what else do I need to do with Tomcat configuration to get it running?   Thanks   Bosco
