Hi, I'm running or rather trying to run JBoss profiler version 2 in JBoss 4.2.1. I have followed the instructions in the README.txt , but cannot get it to work. My setup is as follows: - Windows XP machine - Downloaded Jboss Profiler 2 CR8 - Copied jboss-profiler.jar to JBOSS_HOME/bin - Copied jboss-profiler.properties to JBOSS_HOME/bin - Copied jboss-profiler-plugins.jar to JBOSS_HOME/bin - Copied asm.jar to JBOSS_HOME/bin - Copied jboss-profiler.sar to JBOSS_HOME/server/default/deploy - Edited run.bat to include the following line: set JAVA_OPTS=%JAVA_OPTS% -javaagent:jboss-profiler.jar -Djboss-profiler.properties=jboss-profiler.properties jboss-profiler.properties file has - enable=yes cpu=yes memory=yes includes=org.jboss.profiler.* excludes=* visibility=private save=yes startup=yes repository=no remote=yes store=memory location=. host=localhost port=5400 ejb=yes servlet=yes jsf=yes jmx=yes rmi=yes corba=yes plugin.1=org.jboss.profiler.plugins.Hibernate When I start up jboss, I have the following on console - =============================================================================== JBoss Bootstrap Environment JBOSS_HOME: C:\jboss JAVA: C:\Java\bin\java JAVA_OPTS: -Dprogram.name=run.bat -server -Xms128m -Xmx512m -javaagent:jboss-profiler.jar -Djboss-profiler.properties=jboss-profiler.properties -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 CLASSPATH: C:\Java\lib\tools.jar;C:\jboss\bin\run.jar =============================================================================== JBoss Profiler 2.0.CR8 (Sun Microsystems Inc. 1.5.0_12) JBoss Profiler depends on external communication module 15:10:14,615 INFO [Server] Starting JBoss (MX MicroKernel)... ....... The server boots smoothly. I have an enterprise application(Icefaces /EJBs/Jbpm workflow) ear deployed on the server which I want to profile. Now at the command prompt I say - java -jar jboss-profiler-client.jar startProfiler And I get the following exception - 2008-04-17 15:40:25,299 ERROR [org.jboss.profiler.client.cmd.Client] Can not get connection to server.

While booting, the server log says 'JBoss Profiler depends on external communication module ' Is there some other jar which I need to put somewhere? I tried putting the jboss-remoting.jar, concurrent.jar in JBOSS_HOME/bin. But it would throw other kinds of errors. 2. I went into the jmx console and checked out the Communicator MBean and it has the following configuration - Host localhost Socket false SocketPort 5400 Rmi false RmiPort 5401 Http false HttpPort 5402 It would throw RuntimeException when I try to enable Socket by setting to true. My guess is this being disabled, its not able to establish socket connection ! Is it so? I greatly appreciate any help. :) Thanks, Smita View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4145010#...
