Hello, thanks for your help! now, I got the issue about directory. but encoutered a new problem when attemptting to add a parameter to JVM by executing the following: java -XrunjbossInspector:/tmp,include=org.jboss,ignore=*,start=org.jboss.mq.MQServer the messages are like: this is the new DLL Running process on Windows 4040 Usage: java [-options] class [args...] <to execute a class> or java [-options] -jar jarfile [args....] <to execute a jar file> ....................... I have read the guides and a jboss profiler quick start released in the forum. Installation quick start: 1) copy jboss-profiler-noAOP.sar to the JBoss AS deploy directory 2) put jbossInspector.dll in your PATH (Windows) or libjbossInspector.so in your LD_LIBRARY_PATH (Linux/Unix) 3) copy jboss-profiler.war to the JBoss AS deploy directory Configuration: 1) Add something like this to the JBoss JVM options: -XrunjbossInspector:/tmp/profiler,include=com.unisys,ignore=*,memory=false Make sure the output directory (/tmp/profiler in this example) exists. thanks for your any ideas View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4111097#...
