I am getting the following INFO message from the ConnectionManager when accessed from a Stateless bean:


14:36:01,687 INFO [ConnectionManager] forcing batcher resource cleanup on transaction completion; forgot to close ScrollableResults/Iterator?


The application looks like it is working so what does this mean?

I am using JBoss 4.0.5 GA, but same issues exists with 4.0.4 GA.
I am using Postgresql 8.1 for a database.
I am using Seam, but this error occurs without invoking my UI client.


@Stateless
public class MyTrialBean implements MyTrailRemote
{
@PersistenceContext
private EntityManager em;

...

public String update(Biu biuAttributes)
{
try {
String serialNumber = biuAttributes.getSerialNumber();

List bius = em.createNamedQuery("Biu.findBySerialNumber")
.setParameter("serialNumber", serialNumber)
.getResultList();
if ((bius == null) || (bius.size() == 0)) {
return ProXmlResponse.getError(ProError.BIU_NOT_FOUND);
}

Biu biu = bius.get (0);
biu.setLastContact(new Date());
em.merge(biu);
} catch (Exception e) {
return ProXmlResponse.getError(ProError.BIU_UPDATE_FAILED);
}
}

...



Other posts/replies state that I should close the connection in a finally block.
I have tried various calls to the EntityManager but those usually result in
an error.

I based most of what I am doing here on the EJB3 TrailBlazer demos.

I am looking for more information on this problem to see if it is related to the following more serious ConnectionManager problem.
