You will have to setup the system PATH for the profiling agent to load.
Please refer to the documentation link here
http://dev.eclipse.org/viewcvs/index.cgi/platform/org.eclips e.tptp.platform.agentcontroller/src-native-new/packaging_md/ windows/getting_started.html?root=TPTP_Project&view=co#J ava_15
and you will need the following variables before you start the server
process, as stated in the link.
To run the Java Profiling Agent in standalone mode on Windows, perform the
1.. Set TPTP_AC_HOME=<<Agent Controller Home>>
3.. Set PATH=%JAVA_PROFILER_HOME%;%PATH%;%TPTP_AC_HOME%\bin
4.. Set PATH=%PATH%;%JAVA_HOME%\bin
5.. Execute the Java application with the -agentlib parameter as described
