This only seems to happen when I copy jboss-remoting.jar into the %JBOSS_HOME%/bin directory. When I take it out, JBoss loads fine, but I get the following error about the profiler:- --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- ObjectName: org.jboss.profiler:service=Communicator State: FAILED Reason: java.lang.NoClassDefFoundError: org/jboss/remoting/ServerInvocationHan dler Is this a version issue?
