[news.eclipse.tools] Make a plugin from a java application

[pbeaufil@xxxxxxxx (Pierre Beaufils)]

Hi all,
I'm currently trying to develop a simple plugin from a java application
but i get stuck with a simple problem : i made a plugin.xml which creates
a button in the toolbar to launch my application. Then i modified the main
of the java application with the hello example code :

public class MyClass implements IWorkbenchWindowActionDelegate {
	public void dispose() {
	}
	public void init(IWorkbenchWindow window) {
	}
	public void selectionChanged(IAction action, ISelection selection) {
	}
	public void run(IAction action) {
          //the main application 
          Display display = new Display();
	  Shell shell1 = new Shell(display);
          //etc....

        }
}

If i put something like :"MessageDialog.openInformation(null,null,"Hello,
Eclipse world");" in the function run() it works but if i try to put the
main of my application (so creating a new window) it does not work : in
fact it does nothing.

Does anyone has got an idea to help me ?
