No additional steps are required for WOLips 2.0.0.3821 and above with JProfile 4.3.1 and above.
This tutorial applies for JProfiler 4.2.2.
Modify the plugin.xml of the com.jprofiler.integrations.eclipse plugin from:
<runtime>
<library name="eclipse3-jprofiler.jar"/>
</runtime>
to
<runtime>
<library name="eclipse3-jprofiler.jar">
<export name="*"/>
</library>
</runtime>
Invoke Eclipse from the command line with the -clean option once.
Now you're ready to profile your WebObjects applications (and java apps also) with jprofiler.
