I am struggling with this problem. Please help

MY hibernate.cfg.xml looks like this.

<hibernate-configuration>

<session-factory>
<property name="connection.datasource">jdbc/autopay</property>
<property name="show_sql">true</property>
<property name="dialect">net.sf.hibernate.dialect.DB2Dialect</property>
<property name="transaction.factory_class">net.sf.hibernate.transaction.JTATransactionFactory</property>
<property name="transaction.manager_lookup_class">net.sf.hibernate.transaction.WebSphereTransactionManagerLookup</property>
<property name="jta.UserTransaction">UserTransaction</property>

<mapping resource="resources/xml/BankInformation.hbm.xml"/>

</session-factory>

</hibernate-configuration>




when I start my application I get this stack trace.

This is such a bad problem that it causes my WAS instance to hang and I basically need to restart my WSAD . I cannot even stop the server

That exception is from INSIDE your jdbc.app.DB2Driver! Maybe it is looking for some native drivers that are not available via tha Path or something ? just guessing...

I think this is bug in Hibernate. I downloaded 2.03 and it works. I have posted this as bug

Would you please try to step through your code and find out why a jdbc drivers is Null pointing INSIDE it's call to a loadLibrary() method !?

This is most likely something dependent on your exact environment - and thus most likely not a bug....but if it is then we can't find it without
*you* digging some more than just point a NullPointer into a commercial vendors initializing code.
