Re: EE-Integration Question: How does one do CDI injection on Java EE component classes ?

[Gurkan Erdogdu <gu...@yahoo.com>]

Hi Rohit;

I did it for Apache Tomcat integration for injecting CDI Beans into Servlets/Filters/Tag Libraries. I use OWBInjector class. You could look at org.apache.webbeans.web.tomcat.TomcatInstanceListener, TomcatAnnotProcessor in tomcat6 module.

OWBInjector is a generic class not related with EJB. It takes Java EE components instance and inject CDI beans into it.

Thanks;

--Gurkan

Gurkan,

This will work with EJBs.  How does a container provide injection of
CDI beans into other EE types say JAX-WS Web Services or HTTPServlets
?

Does OpenWebBeans expose an extension point for EE containers to
plugin their own injection service  for injection of CDI managed beans
into EE types.
The mirror image of ResourceInjectionService ?

--Thanks,
Rohit Kelapure
