Hi,

I am developing a simple Hibernate code to run on a websphere portal server 5.1.0.1. I took the sample from Hibernate tutorial and when ran as a java program it works fine. But running on the server it is giving a class not found and give me an exception:

Initial SessionFactory creation failed.java.lang.NoClassDefFoundError: org.hibernate.cfg.Configuration

In my config file I tried running using either the JDBC url or using datasource. But none of them works. The code goes to the catch block when it comes to SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();

Hibernate version: 3.2

Mapping documents:
<session-factory>

<!-- Database connection settings -->
<!-- <property name="connection.driver_class">org.hsqldb.jdbcDriver</property>
<property name="connection.driver_class">com.ibm.db2.jcc.DB2Driver</property> -->

<!-- <property name="connection.url">jdbc:hsqldb:hsql://localhost</property>
<property name="connection.url">jdbc:db2://localhost:50000/SAMPLE</property> -->

<property name="hibernate.connection.datasource">java:/comp/env/jdbc/test</property>

<property name="connection.username">db2admin</property>
<property name="connection.password">db2admin</property>

<property name="connection.pool_size">10</property>

<property name="hibernate.dialect">org.hibernate.dialect.DB2Dialect</property>

<property name="show_sql">true</property>

<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">create</property>

<mapping resource="events/Event.hbm.xml"/>


</session-factory>


Code between sessionFactory.openSession() and session.close():
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();

Event theEvent = new Event();
theEvent.setTitle(title);
theEvent.setDate(theDate);

session.save(theEvent);

session.getTransaction().commit();

session.close();

Problems with Session and transaction handling

You are missing the Hibernate JARs in your Classpath. Please check your Classpath.

Hi Mike,

Thanks for replying. I added the Jars file in the WEB-INF -> lib folder and also to project ->Properties-> Java Build Path added all the libraries.

Is there any other way to add class path while running inside RAD 6.0

Regards.

well that should it be... IMHO RAD and WebSphere are crap.

Sorry but all I can tell you that it is obvious that you are missing the jars in your CP.
