Hey Sahoo -
We are not using WAB's at all - this is all in the bundle and our servlets are registered via HttpService.
I knew the servlets that are registered via that cannot get the injections - and forgot - sorry - bad reference.
And I did verify it does work as advertised - say if we create an MDB inside our bundle and inject the Singleton via @EJB it grabs it OK.
Thanks for your reply.

Subject: Re: OSGi - @EJB injection of an internal @Singleton
Hi Robert,
I am sure you know @EJB can only be used in Java EE managed classes like
Servlets, EJBs, etc., so don't expect it to work if you accidentally
used it in regular classes. I am surprised that it is not even working
for you from a Servlet. May I know how you packaged your bundle? Where
are the EJB and Servlet classes. I am assuming it is a WAB, because it
has both EJB and Servlet. If you have packaged it as a WAB (by
definition a WAB must have Web-ContextPath header), then I don't see the
need to have Export-EJB header at all unless you want the EJBs to be
really exported as service. When the WAB gets deployed, the EJBs will
automatically get deployed. If you send me the log messages that appear
after you deploy this bundle, I can look into it to see what's going on.
Thanks,
Sahoo
