Hi all,
I have been searching the forums for similar issues and found a few that have helped but I am still stuck with the same problem:
I am using hibernate 2.1 within weblogic 8.1.3 and oracle 9.2. I can retrieve successfully from the DB but when I make a change and attempt to persist the changes never appear in the DB. I may have tripped over my own toes by taking bits and pieces from other people posts and responses so I am hoping someone could give a quick look to see if they see anything obvious:
My hibernate.cfg.xml:
Code:
<hibernate-configuration>
<session-factory name="hibernate.session-factory.Oracle">
<property name="connection.datasource">myserverDataSource</property>
<property name="show_sql">true</property>
<property name="dialect">net.sf.hibernate.dialect.OracleDialect</property>
<property name="jndi.class">weblogic.jndi.WLInitialContextFactory</property>
<property name="jndi.url">t3://127.0.0.1:7001</property>
<property name="hibernate.transaction.manager_lookup_class">net.sf.hibernate.transaction.WeblogicTransactionManagerLookup </property>
<property name="hibernate.transaction.factory_class">javax/transaction/UserTransaction</property>
<property name="jta.UserTransaction">net.sf.hibernate.transaction.JTATransactionFactory</property>
<mapping resource="com/mycompany/model/Student.hbm.xml"/>
</session-factory>
</hibernate-configuration>
Hibernate mapping file:
Code:
<hibernate-mapping>

My update call (inside a DAO):
Code:
public void updateStudent(Student student) throws HibernateException
{
Session hbnsession = null;
List results = null;
try
{
hbnsession = HibernateSessionManager.getSession();
//TODO: add optimistic locking so we get the student, compare the details
//and if no changes update else return a RecordChangedException
hbnsession.update(student);
}
catch (HibernateException e)
{
log.error(e.getMessage());
//TODO: map this to a generic infrastructure exception
throw e;
}
}
finally the session bean method that calls the dao:
Code:
public void updateStudent(Student criteria)
throws Exception
{
log.info("updating student ID:"+criteria.getStudentId());
try
{
new StudentDAO().updateStudent(criteria);
//we want our container to handle transactions
HibernateSessionManager.commitTransaction();
}
catch(Exception e)
{
throw e; //we logged it already
}
finally
{
HibernateSessionManager.closeSession();
}
}
Any advice would really be appreciated.
Thanks!
