Hibernate version 3.0
I was walking throught the QuickStart with Tomcat and followed the instructions as closely as possible.
Creation of the SessionFactory produces the ExceptionInInitializerError.
sessionFactory = new Configuration().configure().buildSessionFactory();
I am using all the latest JAR files that came with the download.

I am also using Oracles' JDBC JAR file
ojdbc14.jar

The only difference I am doing is that I am not using Tomcats DBCP... I have configured the hibernate.cfg.xml file with the following:
<hibernate-configuration>

<session-factory>
<!-- properties -->
<property name="hibernate.connection.username">eric</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@ds11.dev.gbl.chase.com:1521:GIBDEV9</property>
<property name="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</property>
<property name="hibernate.connection.password">123xxx</property>
<property name="hibernate.connection.driver_class">oracle.jdbc.pool.OracleConnectionPoolDataSource</property>

<!-- mapping files -->
<!-- The following mapping element was auto-generated in -->
<!-- order for this file to conform to the Hibernate DTD -->
<mapping resource="Cat.hbm.xml"/>

</session-factory>

</hibernate-configuration>

Any help you could provide is greatly appreciated.

Thank You

Add asm.jar to classpath / lib directory.

Thank You... asm.jar was one of the additional JARS I needed to add.

However after adding that I also had to add jta.jar because I was getting the following error.


Anyway... for anyone else following the Getting Started, make sure you also add asm.jar and jta.jar

Happy Coding.
