Profiling your Java applications with JProfiler

Download JProfiler v5.2.1 from here.

Read build-in help Reference → Managing Sessions → Remote Session Invocation Table. System should be able to find jprofilerti.dll in system path. In my case run sequence is the following:

set PATH=%PATH%;%Applications%\JProfiler\bin\windows
set VM_OPT=-Xmx1200m -Xbootclasspath/a:%Applications%\JProfiler\bin\agent.jar -agentlib:jprofilerti
 
call java %VM_OPT% -jar lib/root.jar

or for Linux:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/jprofiler/linux-x86
 
VM_OPT="-Xmx1200m -Xbootclasspath/a:$HOME/jprofiler/agent.jar -agentlib:jprofilerti"
 
java $VM_OPT -jar lib/root.jar $*

Other options:
-agentlib:jprofilerti=port=8849 to specify the port
-agentlib:jprofilerti=nowait,id=100,config=/work/config.xml to run in nowait mode (note: config.xml should contain the license information)
