What is difference between @Inject and @InjectComponent since we declare it before component.

Hi experts,

I have a snippet code as below:

@Inject
private Zone tZone;

@InjectComponent
private Zone tZone;

So I don't understand what is difference if I use @Inject or
@InjectComponent for component in Tapestry ? If anyone knows, can you
please let me know why. I really appreciate.

Thanks,
Duy.
