Hibernate3.0 with Weblogic7.0

[sridhar vu]

Hello,
I'm migrating my web application from Tomcat 5.0.30 to weblogic 7.0. I'm having problem with hibernate when I deploy it. Can some one please help me with this.

Configuration settings are given below.

hibernate.cfg.xml

<hibernate-configuration>
<session-factory>
<property name="jndi.url">t3://localhost:7001</property>
<property name="jndi.class">weblogic.jndi.WLInitialContextFactory</property>
<property name="connection.datasource">jdbc/lossforecast</property>
<property name="show_sql">false</property>
<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
<!-- Mapping files -->
<mapping resource="com/test/lossforecast/dao/hibernate/User.hbm.xml"/>
</session-factory>
</hibernate-configuration>

Class where I'm getting the SessionFactory:

public class HibernateUtil {
private static final SessionFactory sessionFactory;
private static Log log = LogFactory.getLog(HibernateUtil.class.getName());

static {
try {
sessionFactory = new Configuration().configure()
.buildSessionFactory();
} catch (Throwable ex) {
log.error("HibernateUtil error", ex);
throw new ExceptionInInitializerError(ex);
}
}
}

See Hibernate3 Migration Guide for part of the answer. Instead of modifing my WebLogic pre-classpath, I added the hibernate property:

<prop key="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</prop>

As I understand it, this forces Hibernate to use version 2 query parser.
