Step 1 - Download files
Download profilerJ from here and extract the files to a directory of your choice. Windows users should use the Windows Installer profilerJ-1.4.0.msi instead. The installation directory will be something like "c:\program files\terrasoft\profilerj".
To keep it simple, this tutorial assumes that the installation directory is c:\profilerj. Also download the examples (examples.jar) used for the following steps.
Now try to start a class contained in examples.jar in order to verify if the java runtime is properly setup. Create the batch file c:\profilerj\example01.bat (or a shell script on Unix respectively) containing the line
java -cp examples.jar com.terrasoft.profilerj.tutorial.Example01
and start the batch file. Example01 simply prints "Example01 running ..." and performs some lengthy operations.
