[news.eclipse.tools] How to get the install-directory of a plugin?

[Philipp.Bouillon@xxxxxxxxxxx (Philipp Bouillon)]

I have written a launcher for Eclipse. This launcher launches a class that
is part of the PlugIn-package, and I have to set the classpath for the
VMRunnerConfiguration to the binary-directory of my plugin.
How can I determine this binary directory?
I tried to determine the path by calling the "getInstallURL"-method of my
IPluginDescriptor, but it points to
"runtime-workspace/plugin/<mypluginname>" and this directory does not
exist... Do I have to install my plug-in to test it?? Or is there another
way of determining the install-path?

Thanks for your help,
