I’m working with Eclipse 3.2.2 RCP right now and I’m getting an exception that I want to display on screen. I found in the eclipsepedia that we must use ErrorDialog to report errors:

try {
// ...
} catch (InvocationTargetException e) {
  IStatus status = new Status(IStatus.ERROR, Application.ID, 1, "Exception found.", e.getCause());
  ErrorDialog.openError(window.getShell(),"Error while loading file", null,status);                     
}
