JBoss is not beginning transaction
holmes.j Sep 19, 2006 3:19 PMHi,
I'm using JBoss 4.0.4-GA with Hibernate 3.2CR4 and EJB 2.1. Hibernate is complaining that "load is not valid without active transaction" This comes form the TransactionManager that is checking to see if the Transaction is active. The transaction exists, it just has not begun.
I have a stateless session bean using CMT that looks like this ...
/** * @ejb.bean name="GeoFeatureServer" * jndi-name="com.free2be.framework.gis.feature.GeoFeatureServerHome" * type="Stateless" view-type="remote" * @ejb.transaction type="Required" */ public abstract class GeoFeatureServerBean implements SessionBean { /** * @ejb.interface-method */ public GeoFeature findGeoFeature(GeoFeaturePk geoFeaturePk) throws NoSuchElementException { GeoFeature value = (GeoFeature) cache.getByKey(geoFeaturePk); if (value == null) { getLogger().debug(geoFeaturePk + " not cached...loading"); value = getGeoFeatureDao().findById(geoFeaturePk, false); cache.addToCache(value); } return value; } }
The DAO code looks like this ...
@SuppressWarnings("unchecked") public V findById(long id, boolean lock) { V entity; try { Session session = getSession(); // Transaction tx = session.beginTransaction(); if (lock) entity = (V) session.load(getPersistentClass(), id, LockMode.UPGRADE); else entity = (V) session.load(getPersistentClass(), id); } catch (HibernateException e) { throw new NoSuchElementException(e.getMessage()); } return entity; }
If I un-comment the session.beginTransaction(), the exception won't be thrown. However, we're using CMT, so I shouldn't have to do that. In fact, I shouldn't be allowed to do that. Touching the transaction should throw an exception AFAIK.
My hibernate.properties file ...
hibernate.dialect=org.hibernate.dialect.MySQLDialect hibernate.connection.driver_class=com.mysql.jdbc.Driver hibernate.connection.url=jdbc:mysql://integration:3306/mbgeo hibernate.connection.username=xxxx hibernate.connection.password=xxxx #don't use hibernate's pooling! http://www.hibernate.org/hib_docs/v3/reference/en/html/session-configuration.html hibernate.c3p0.min_size=5 hibernate.c3p0.max_size=20 hibernate.c3p0.timeout=1800 hibernate.c3p0.max_statements=50 hibernate.session_factory_name=hibernate/session_factory jta.UserTransaction=UserTransaction #hibernate.current_session_context_class=jta #can leave unset, default is jta hibernate.transaction.factory_class=org.hibernate.transaction.CMTTransactionFactory hibernate.transaction.manager_lookup_class=org.hibernate.transaction.JBossTransactionManagerLookup hibernate.transaction.flush_before_completion=true hibernate.cache.provider_class=org.hibernate.cache.NoCacheProvider hibernate.show_sql=true hibernate.format_sql=true hibernate.generate_statistics=true hibernate.bytecode.use_reflection_optimizer=false hibernate.bytecode.provider=javassist
Anybody have any ideas as to what I'm doing wrong?
