====== Profiling your Java applications with [[http://www.ej-technologies.com/download/jprofiler/|JProfiler]] ======

  * Download JProfiler v5.2.1 from [[torrents>1470951|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:
    <code dos>
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
</code> or for Linux: <code bash>
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 $*
</code>
   * 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) \\
