OK, I found the problem. I was not starting JBoss from the bin directory and I did not have a full path to the jboss-profiler.jar file in the JAVA_OPTS. Fixing that gets things going. Do I need to add a path to the jboss-profiler.properties -D options as well? Also, I notice there is such a file in the jboss-profiler.jar file as well as the one I put in the put directory. Which one gets used? Now I have problem with the profiler communications. I get a NoClassDefFoundError for org/jboss/remoting/ServerInvocationHandler during startup, and I can't connect with the client. I assume I am missing some jar file, but which one?
