I duly copied jboss-profiler-noAOP.jar in to my server/deploy directory. However, I see an error in server.log on startup. Here is top of stack trace: 2008-05-30 14:03:19,656 DEBUG [org.jboss.deployment.SARDeployer] create operation failed for package file:/C:/jboss/jboss-3.2.7/server/default/deploy/jboss-profiler-noAOP.sar org.jboss.deployment.DeploymentException: Unknown xmbean type null; -nested throwable: (javax.management.NotCompliantMBeanException: Unknown xmbean type null) at org.jboss.system.ServiceConfigurator.install(ServiceConfigurator.java:142) As a result, of course, I don't see the mbean in jmx-console. jboss-profile web app appears to work okay and there is nothing else strange in log file. Using: JBoss 3.2.7 jboss-profiler-1.0.CR4 Java 1.5.0_10-b03 on Windows XP Do I have some kind of version incompatibility? I find no mention of this problem elsewhere.
