JBoss Profiler 1.0 and JBoss Profiler 2.0 are two very different things. JBoss Profiler 1.0 is a log based JVMTI profiler. JBoss Profiler 2.0 is currently a Java5+ profiler. Work is being done on a RichFaces UI and a JVMTI/HPROF backend. I have converted the documentation for JBoss Profiler 2 to Docbook that generates HTML and PDF as the result. Please, checkout the branch in SVN. As for javasisst.jar in bin/ -- seems like you are running JBoss AS 4.2 and the requirement is listed in the new documentation. It will be released in JBoss 2.0.0.Beta4 - hopefully together with the initial version of the web ui. HTH View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4227517#...
