RE: Connection error using Spring/Hibernate/JBoss


The issue I had was that sometimes JBoss would complain about having to=20
release a connection for me. Additionally, I earlier had some cases=20
where it said it didn't know the connection I was trying to release. I=20
did a fair amount of tracing through our whole code when this was=20
happeing, and am almost 100% sure it's a jboss problem. This is=20
corroborated by the fact that the problem was _much_ worse in JBoss=20
3.2.2RC3 than in the current 3.2.3 I am using.  As of a few weeks ago I=20
actually got rid of all EJBs except for a message driven bean which is=20
still around, and I still seem to get the complaint releasing the=20
connection for me, in some cases, as far as I know (have to verify this=20
completely).

So I don't think this is quite the same issue. I was going a lot of mix=20
and matching of CMT and Spring, and never got the warning below. I will=20
follow up on the post below...

[Colin S. <col...@ex...>]

As far as I can tell all is ok.   Now to tell you the truth, the only=20
reason it was ever happening for me is that due to something being=20
misconfigured; a tx was not rolling back on a checked exception, so=20
commit was still being called on a Hibernate Session that had thrown an=20
exception, which caused a flush to happen at that inopportune time. My=20
current code would now never get that far. But from what I remember I=20
switched over to the fixed Spring code before I reworked my code, and=20
all was ok...
