Hi, so far, I was successuflly able to set up the profiler as I see the MBean in the JMX console. Starting works fine, but it seems that the proerties file is completely ignored (which I put in the server's bin directory and included the setting in the run.conf). Secondly, if I try to issue a stopProfiler or snapshot command, I get: java.lang.NullPointerException at org.jboss.profiler.agent.ClassUtil.getClasses(ClassUtil.java:80) at org.jboss.profiler.agent.Profiler.stopProfiler(Profiler.java:146) at org.jboss.profiler.connectors.AbstractHandler.handleCommand(AbstractH andler.java:51) at org.jboss.profiler.connectors.SocketHandler.invoke(SocketHandler.java :50) at org.jboss.remoting.ServerInvoker.invoke(ServerInvoker.java:734) at org.jboss.remoting.transport.socket.ServerThread.processInvocation(Se rverThread.java:560) at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.j ava:369) at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.jav a:165) at org.jboss.remoting.MicroRemoteClientInvoker.invoke(MicroRemoteClientI nvoker.java:163) at org.jboss.remoting.Client.invoke(Client.java:1550) at org.jboss.remoting.Client.invoke(Client.java:530) at org.jboss.remoting.Client.invoke(Client.java:518) at org.jboss.profiler.client.cmd.Client.main(Client.java:252) even though I tried to add some classes before (and also set the include proerty in the file). I am using JBoss 4.0.4-GA right now. Is there anything which I can change? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4123356#...
