Well, there are currently two active branches. JBoss Profiler 2.x: Java 5 profiler with text output -- a web front-end is in development. The agent is 100% Java code and is therefore lacking some functionality. A native agent is in development. JBoss Profiler 1.x: JVMTI profiler with web front-end. Both versions can be used depending on your needs. HTH View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4193579#...
