public class SampleAction implements IWorkbenchWindowActionDelegate, HelloWorld {

• • Add a private field

private HelloWorld helloWorld;

• Modify the constructor (Activator is testproject.Activator)

	public SampleAction() {
		helloWorld = (HelloWorld)ScriptUtil.registerProxy(this, HelloWorld.class, Activator.class.getClassLoader());
