lets not forget the important part, assuming the ejb thing works just like
wicket-spring. things injected are actually proxies not beans themselves.
these proxies can be serialized safely - they do not have a hard link to the
underlying ejb bean. if you do not do this and keep a reference to an ejb
bean in wicket components two things can happen:
a) you get a not serializable exception when wicket/servlet container needs
to serialize something
b) worse, the bean is serializable and you drag it along with the wicket
components into your session ending up with a useless clone

Hi Korbinian,
yes, you are right, you can create your lookup methods (with your
IDE or writing the classes), in the same way you can extract beans
from Spring calling applicationContext.get("beanName").
However, I prefer to write less code and let the infrastructure be
responsible of doing all the boring stuff. Since Java EE 5 allows you
to inject ejb dependencies through the @EJB annotation, I thought it
would be useful to extend this functionality to wicket pages, in the
same way we have @SpringBean annotation for injecting spring beans.
