Integration

Hi all,

i am trying to develop a small/custom application to process the .jfr files from multiple jrockit JVM (the JRMC is not friendly enough
when processing multiple files and can't automate some typical issue/problem checking)

i refer to the API document here: http://docs.oracle.com/cd/E15289_01/apirefs.40/e26998/com/jrockit/mc/flightrecorder/FlightRecording.html

e.g.

---------------
FlightRecording recording = FlightRecording.createFromFile(new File("path_to_recording.jfr"));

//more code below

---------------

i add several .jar files in the classpath (jars in folder missioncontrol/plugins) for compilation.

When i try to run the application, i get the following error.

can anybody help to show me how to setup the environment/classpath so as to run an application for reading the .jfr file?

thank you.
