how to change your eclipse rcp application's title and icon

if you hurry anyway,you can do that.

public class OptipngWrapperWorkbenchAdvisor extends WorkbenchAdvisor{

public void postWindowOpen(IWorkbenchWindowConfigurer configurer) {
configurer.setTitle(Messages.getString("optipng_title"));
Image logoImage=ImageDescriptor.createFromURL(OptipngWrapperPlugin.getDefault().find(new Path("icons/akj_eclipse.png"))).createImage(); //$NON-NLS-1$
configurer.getWindow().getShell().setImage(logoImage);
}

}

but this approach has problem. selected icon isn't deliverd to other shell (Help or Updates)
that's not so important thing.

but I recomend you use product extension point.

<product name="akJ Speech Tools"
