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. 14:52:08,817 WARN [JDBCExceptionReporter] SQL Error: 0, SQLState: null 14:52:08,817 ERROR [JDBCExceptionReporter] No ManagedConnections available within configured blocking timeout ( 30000 [ms] ); - nested throwable: (javax.resource.ResourceException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] )) 14:52:08,817 ERROR [STDERR] Nov 30, 2006 2:52:08 PM checkStats INFO: PurgeStatsBean.checkStats()...Failed View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3990196#...
