MyFaces CODI and Weld 1.0.1
Hey all,
we are currently developing an application based on Weld 1.0.1 and
MyFaces CODI. Unfortunately we have some strange problems regarding
CODI's @Transactional not always being applied correctly. It seems to
be completely ignored in some situations.
I've reproduced this problem with Matthias' Modern-EE-JSF2.0 example
application. I did just two modifications:
1. Weld doesn't support to inject the EntityManager via
@PersistenceContext. So I created a class named EntityManagerProducer
to create request scoped EntityManager instances. Then I replaced
@PersistenceContext in the DAO with @Inject. This works fine with
OpenWebBeans.
2. Then I removed OpenWebBeans and added Weld 1.0.1 to the
dependencies. After that @Transactional immediately stopped working.
It seems like the TransactionalInterceptor doesn't get invoked at all.
No transactions are started and changes to the database aren't
persisted any more.
You can get the example application here:
https://github.com/chkal/modern-ee-app20
Here are the modifications I made to the application:
https://github.com/chkal/modern-ee-app20/commits/master
Does anyone have an idea what is causing this? I'm not really sure if
it is a CODI or a Weld issue.
Thanks
Christian

Try to "unzip" the jar into web-inf/classes and add its beans.xml content to
the one in web-inf.
This was suggested to my by the glassfish team... :-)

Hi Mark,
thank you very much for your response. I've tried your suggestion and
it worked great. I didn't knew about the BDA part in the spec and
assumed that CODI's beans.xml would globally enable the interceptor.
You are right! This BDA stuff is crap! :-)
@Matthias: Nice workaround! ;)
Thanks
Christian

Hi Christian!
The major difference between Weld and OpenWebBeans in the interceptor area is that Weld strictly follows the "Bean Definition Archive" (BDA) part of the spec. This got added pretty late (in the last few weeks before the spec went final and imo is complete crap [1] ;)
In Weld you have to add the <interceptors> section to ALL jars as well as to the WAR you like to use the interceptor in. Whereas in OWB it is enough to just have it enabled in 1 of the beans.xml files.
So please try adding those section to all your beans.xml files and plz report back if that worked out.
LieGrue,
