I have created an eclipseRunner class which launches an eclipse instance
as given below..

String arr[]=new String[4];
try {
//set the command line args of eclipse
arr[0]="-data"; ;
arr[1]="D:/eclipse/workspace2";
arr[2]="-application";
arr[3]="org.eclipse.ui.workbench";
//below is org.eclipse.core.launcher.Main class
Main main=new Main();
main.run(arr);//start the execution using my arguements

Now I wish to get workspace Handle in my EclipseRunner class .
ResourcesPlugin.getWorkspace() returns null hwich I had expected.
Can anyone give me something to work on??

Eclipse manages classloading for plug-ins. Your standalone application
can run Eclipse on the same VM, but you will need some trick to be able
to reach code in plug-in from your application. The ResourcesPlugin
class you access from your aplication is not the same available to code
running as plug-ins (that one *is* properly initialized).

So you need to devise some way for communicating with that code. You
could do it by using some shared object (ThreadLocals, for instance) or
using any inter-process communication mechanism. In either way, you
would need a plug-in running in Eclipse to the work in that side.

But honestly, why do you need to do that? Why can't you run your code as
a plug-in?
