EJB example in YouTube video

Hi,

I am working my way through the "Apache TomEE: JavaEE 6 Web Profile on Tomcat" video on youtube and I have a question. 

The EJB annotation example, right around 20 minutes, does that only works when used in a Servlet?

So what has to be done to use the annotation in an arbitrary class?

For example, what has to be done to use it in a Component of the Wicket framework?

I know the wicket community has already implemented a CDI 1.1, which I already got running.
So this is just a question of understanding.
What is the simplest way of using the EJB Annotation on such Component?
Should the wicket cdi module be used or is there a more direct way of using EJB ?

A beans.xml file to activate cdi and an empty constructor is enough

Hi,

ok, so what is needed to turn a class to a managed class?

Hi

EJB can be injected as CDI beans too so you can use @Inject for them.
EJB and CDI beans have the same limitations = you can inject them in
all managed classes.
