CODI: Wiki "JPA Usage"
I tried "Using one (default) Entity Manager"
(https://cwiki.apache.org/confluence/display/EXTCDI/JPA+Usage):
public class DataBaseProducer
{
@Produces
@PersistenceContext(unitName="default")
@Default
private EntityManager entityManager;
public void dispose(@Disposes @Default EntityManager entityManager)
{
if(entityManager.isOpen())
{
entityManager.close();
}
}
}
This does not work - I get following error at "@Disposes" in eclipse:
"There is no producer method declared by the (same) bean class that is
assignable to the disposed parameter of a disposer method [JSR-299
§3.3.7]"
Whats wrong?
thx, gernot

Re: CODI: Wiki "JPA Usage"

Might well be, but imo it's also much easier to debug if having a producer method ;)
Plus: producer fields for 'EE Resources' have a slightly different behaviour than the same if produced with a producer method. See "3.5 Resources". This is imo pretty sick, but that's the way it is...

Re: CODI: Wiki "JPA Usage"
Posted by Gerhard Petracek <ge...@gmail.com>.
thx mark for creating the spec. issue.
it's quite interesting that it worked with owb as well as with weld :)
-> in this case the jboss-tools plugin was correct.
@gernot:
i've updated the wiki.
however, since it used to work with owb the issue might be something else.

Yes you are right. 3.3.7 actually only talks about 'producer methods'

I've created https://issues.jboss.org/browse/CDI-145 in the spec issue tracker.
Gerhard, I also think that it works in OWB, but it's not really spec conform and might have rough edges ;) So we should also move our example to using producer methods.
Thanks for the report, Gernot!

Thanks for answering!
I did some investigations:
(1) It's the JBosstools which reports the error (not core Eclipse WTP).
(2) I deinstalled JBosstools - in Eclipse now everything is OK - I
deployed it on Tomcat 7 (OWB 1.1, Hibernate 3.6) - and got following
error:
SCHWERWIEGEND:

(3) I also did a look into CDI spec:
Disposer Methods are only specified in the producer methods section
(chapter 3.3). And at 3.3.7 disposer methods are only bound to
producer methods (and not to producer fields)
In chapter 3.4 "producer fields" there are no references to disposer methods.
==> in my opinion the spec isn't clear?!
Why do I get the above stack trace?
If I change my code to use a producer method (not field) everything works:
@RequestScoped
public class PersistenceProducer
{
@PersistenceContext(unitName = "default")
@Default
private EntityManager entityManager;
@Produces
public EntityManager getEntityManager()
{
return entityManager;
}
public void dispose(@Disposes @Default EntityManager entityManager)
{
if (entityManager.isOpen())
{
entityManager.close();
}
}
}

hi gernot,
i would say: don't rely on the eclipse-plugin. at least some months ago it
showed a lot of wrong findings in a demo which works pretty fine (with owb
as well as weld).
you can find a working example e.g. at [1]
