Using wicket with OpenEjb

[Jesper Skov <js...@zoftcorp.dk>]

Hi

I don't know if this problem has already been addressed by someone
else, but when I started looking at migrating my Wicket application
from Glassfish to OpenEjb, the injection magic failed.

I have hacked my way around that issue with the below code.

It would need some TLC to be suitable for inclusion in the project.
Maybe just make a new JavaEEComponentInjector clone class with the
added magic, or extend the existing class to allow lookup properties
to be provided!?!?!

Anyway, use it as you see fit.

Cheers,
Jesper Skov

I don't really know Wicket at all -- to tell you the truth I'd have to look at the website to tell you what it does :)

But in terms of better injection, we could probably give wicket components the full Java EE treatment and injection capabilities that you can get in a Servlet, EJB, or other type of managed component.

Any Wicket devs attending ApacheCon?  Would love to sit down with someone and see what kind of cool things we could do.
