Hi all,
My application has been running succesfully for a couple of month in
development now, performance and scalability tests are showing that we are
setting up and committing a lot of transactions so I started to look at setting
the transaction attributes of my session beans correctly.
Once I started doing that I am getting a lot of:

I am absolutely sure that I am always closing all jdbc resources. That's what
the DatabaseService and the BusinessContext are for (doing try {} finally
{jdbcResource.close()}).
As explained, the above exception started to show up once I changed the
transaction attribute of the ConnectionSessionIdPersistenceManager from
"Required" to "Supports" as the method is only reading stuff from the database
and not doing any inserts, updates or deletes.
How can I avoid the exception?
For your information, I am still running on:
