Google Web Toolkit and JRUN

Hey Charlie, thanks for the help. Problem solved!!  Embarrassing, but potentially useful to someone, so here goes... I am using the single server instance, by the way, and was putting my jar file in WEB-INF/lib, as you said. The problem was with the jar file.  I was teaching myself Ant at the same time, and just assumed that part was okay, but I had been jar'ing the src folder instead of the bin one.  OOPS! How I came to the solution though was by switching from CF 8 Dev (with JRUN) to Open Blue Dragon (with Jetty).  Starting Jetty from the command line gave me instant feedback about what was wrong, whereas when I started CF as a Windows service (which starts JRUN), there's no feedback to help lead me to the problem. Thanks again for your help!  Nice to meet you. e.
