Attach jboss profiler to test program. Execute the client snapshot command and got the following error in the output of the test program. Exception in thread "WorkerThread#0[127.0.0.1:4024]" java.lang.NoClassDefFoundError: org/jboss/serial/io/JBossObjectInputStream     at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:398)     at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:173) The client program kept running after the exception, i killed after 30 seconds. *Step 2*. Looks like i did not have the jboss-serialization jar so I wrote a test with the following code. Class.forName("org.jboss.serial.io.JBossObjectInputStream"); Got the same exception Then I included the following jar from $Jboss6Home\client\jboss-serialization.jar and ran the test again and got the following exception java.lang.NoClassDefFoundError: gnu/trove/TObjectHashingStrategy     at org.jboss.serial.io.JBossObjectInputStream.<clinit>(JBossObjectInputStream.java:56)     at java.lang.Class.forName0(Native Method)     at java.lang.Class.forName(Class.java:164)     at com.org.domain.JbossProfilerTest.testname(JbossProfilerTest.java:9)     at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)     at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)     at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)     at java.lang.reflect.Method.invoke(Method.java:585)     at org.junit.internal.runners.TestMethodRunner.executeMethodBody(TestMethodRunner.java:99)     at org.junit.internal.runners.TestMethodRunner.runUnprotected(TestMethodRunner.java:81)     at org.junit.internal.runners.BeforeAndAfterRunner.runProtected(BeforeAndAfterRunner.java:34)     at org.junit.internal.runners.TestMethodRunner.runMethod(TestMethodRunner.java:75)     at org.junit.internal.runners.TestMethodRunner.run(TestMethodRunner.java:45)     at org.junit.internal.runners.TestClassMethodsRunner.invokeTestMethod(TestClassMethodsRunner.java:66)     at org.junit.internal.runners.TestClassMethodsRunner.run(TestClassMethodsRunner.java:35)     at org.junit.internal.runners.TestClassRunner$1.runUnprotected(TestClassRunner.java:42)     at org.junit.internal.runners.BeforeAndAfterRunner.runProtected(BeforeAndAfterRunner.java:34)     at org.junit.internal.runners.TestClassRunner.run(TestClassRunner.java:52)     at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:38)     at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38)     at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460)     at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673)     at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386)     at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) *Step 3*. I found the trove jar at $Jboss6Home\client\trove.jar again ran the test in step 2 and it ran successfully. So I decided to run step 1 again but again i got the same behviour(execption and client not closing).  All jars from the profiler zip are also included in the classpath of the test program. Here is the === jboss-profiler.properties === enable=yes precompiled=no cpu=yes memory=yes includes=org.jboss.profiler.*,com.org.domain.* excludes=* visibility=private save=yes savelocation=store startup=yes repository=no remote=yes store=file location=store host=localhost port=5400 ejb=no servlet=no jsf=no jmx=no rmi=no corba=no Here is the === jboss-profiler-client.properties === protocol=socket host=localhost port=5400 threshold=1.0 savelocation=. let me know if there is anything else you would like me to try. Thanks. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/566109#566109] Start a new discussion in JBoss Profiler Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
