Using Jboss 4.0.4 GA: I have a Servlet for getting image data out of a mysql database. The data comes out of a EJB 3 entity bean, which I load via the EntityManager. The loading works fine, however, if I have a page with more than one image like this on it, I get the following error on the console. Although the stacktrace continues to my code, the Exception is not thrown (my catch (Throwable e) is never called by this), but printed directly. anonymous wrote : | 13:05:29,203 WARN [TxConnectionManager] Connection error occured: [EMAIL PROTECTED] [EMAIL PROTECTED] handles=0 lastUse=1150628728562 permit=true trackByTx=false [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] txSync=null] | java.sql.SQLException: Can't call rollback when autocommit=true | at com.mysql.jdbc.Connection.rollback(Connection.java:4729) | at org.jboss.resource.adapter.jdbc.local.LocalManagedConnection.rollback(LocalManagedConnection.java:86) | at org.jboss.resource.connectionmanager.TxConnectionManager$TxConnectionEventListener.tidyup(TxConnectionManager.java:667) | at org.jboss.resource.connectionmanager.BaseConnectionManager2.returnManagedConnection(BaseConnectionManager2.java:336) | at org.jboss.resource.connectionmanager.TxConnectionManager$TxConnectionEventListener.connectionClosed(TxConnectionManager.java:623) | at org.jboss.resource.adapter.jdbc.BaseWrapperManagedConnection.closeHandle(BaseWrapperManagedConnection.java:266) | at org.jboss.resource.adapter.jdbc.WrappedConnection.close(WrappedConnection.java:129) | at org.hibernate.connection.DatasourceConnectionProvider.closeConnection(DatasourceConnectionProvider.java:74) | at org.hibernate.jdbc.ConnectionManager.closeConnection(ConnectionManager.java:445) | at org.hibernate.jdbc.ConnectionManager.aggressiveRelease(ConnectionManager.java:400) | at org.hibernate.jdbc.ConnectionManager.afterStatement(ConnectionManager.java:275) | at org.hibernate.jdbc.AbstractBatcher.closePreparedStatement(AbstractBatcher.java:535) | at org.hibernate.jdbc.AbstractBatcher.closeStatement(AbstractBatcher.java:265) | at org.hibernate.jdbc.AbstractBatcher.closeQueryStatement(AbstractBatcher.java:281) | at org.hibernate.jdbc.AbstractBatcher.closeQueryStatement(AbstractBatcher.java:209) | at org.hibernate.loader.Loader.doQuery(Loader.java:714) | at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:224) | at org.hibernate.loader.Loader.loadEntity(Loader.java:1785) | at org.hibernate.loader.entity.AbstractEntityLoader.load(AbstractEntityLoader.java:48) | at org.hibernate.loader.entity.AbstractEntityLoader.load(AbstractEntityLoader.java:42) | at org.hibernate.persister.entity.AbstractEntityPersister.load(AbstractEntityPersister.java:2821) | at org.hibernate.event.def.DefaultLoadEventListener.loadFromDatasource(DefaultLoadEventListener.java:370) | at org.hibernate.event.def.DefaultLoadEventListener.doLoad(DefaultLoadEventListener.java:351) | at org.hibernate.event.def.DefaultLoadEventListener.load(DefaultLoadEventListener.java:122) | at org.hibernate.event.def.DefaultLoadEventListener.proxyOrLoad(DefaultLoadEventListener.java:178) | at org.hibernate.event.def.DefaultLoadEventListener.onLoad(DefaultLoadEventListener.java:86) | at org.hibernate.impl.SessionImpl.fireLoad(SessionImpl.java:871) | at org.hibernate.impl.SessionImpl.get(SessionImpl.java:808) | at org.hibernate.impl.SessionImpl.get(SessionImpl.java:801) | at org.hibernate.ejb.AbstractEntityManagerImpl.find(AbstractEntityManagerImpl.java:155) |
Does anybody have a clue what that means, or how to avoid this? I also tried turning autocommit=false in the datasource (trying various ways), but this errors keeps popping up.
