Hi Lai:
I readed some source code of Struts2, and realized that
the property [theme] is defined in class [org.apache.struts2.components.UIBean]
but not in class [org.apache.struts2.components.Component].
So i think if you want to render something with your tag, and
appoint the theme by the attribute [theme], maybe you should
extend your tag class from [UIBean] instead of [Component].
Which means, your class should like:
public class Hello extends UIBean {
...
...
}
