Adding Classes at Run-time
by Jason Lee
I have an odd question. I have a situation where I'm manually opening a
JAR and adding its classes to the ClassLoader. What I'd like to be able
to do is have Weld scan these classes for any relevant annotations and
take the proper actions, just as if the JARs were in the classpath when
the application started. I've been staring at the JavaDocs (build
locally, btw, as I can't find them on the web :| ) but I don't see any
way to request that Weld inspect a given class. Is it there and I'm
missing it? Am I going to have cobble together that functionality? Am
I asking for something that can't be done (right now)? Any nudges in
the right direction would be much appreciated. :)

tx services
by Ales Justin
IMO TransactionServices should also expose TransactionManager.
Since with AS7, which hides TM from JNDI, one cannot easily register XAResources:
Transaction
public boolean enlistResource(XAResource xaRes) throws RollbackException, IllegalStateException, SystemException
or suspending/resuming current Tx.
Specially XAResources handling is a must to be able to enlist if you're doing some non-trivial tx-based work.
This way the integration layer would make sure the TM is exposed as a CDI service.
Wdyt?
