Hi all,
I am new to Hibernate. Please help me with this exception.

My hibernate.cfg.xml is :

<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">oracle.jdbc.OracleDriver</property>
<property name="connection.url">jdbc:oracle:thin:@192.168.0.2:1521:TPSS10G</property>
<property name="connection.username">gps</property>
<property name="connection.password">gps</property>

<property name="dialect">org.hibernate.dialect.OracleDialect</property>

<!-- only set to true for debug - PLEASE don't check this in set to true -->
<property name="show_sql">false</property>

<property name="transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
<property name="transaction.manager_lookup_class">org.hibernate.transaction.WeblogicTransactionManagerLookup</property>
<property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>

<property name="hibernate.transaction.flush_before_completion">true</property>
<property name="hibernate.transaction.auto_close_session">true</property>

<mapping resource="dummy/Dummy.hbm.xml"/>
</session-factory>
</hibernate-configuration>


And my code is

try {
// Create the SessionFactory from hibernate.cfg.xml
System.out.println("Creating Configuration.");
sessionFactory = new Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed. " + ex);
throw new ExceptionInInitializerError(ex);
}

And when I execute it, the following xception is throw at the above line :

Initial SessionFactory creation failed. org.hibernate.HibernateException: Could not locate TransactionManager

Please help me with what input to be specified and in which file.

Waiting for the reply.

If you run it is outside of WebLogic container than it will not work.

Remove the following lines and it should resolve the issue:
<property name="transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
<property name="transaction.manager_lookup_class">org.hibernate.transaction.WeblogicTransactionManagerLookup</property>
