I'm using Hibernate 2.1.7 with SDK 5.0 and Daffodil database version 3.4.

I'm able to create a session. When beginning a transaction, I get the following stack trace:

Exception in thread "main" java.lang.UnsupportedOperationException: The user must supply a JDBC connection
at net.sf.hibernate.connection.UserSuppliedConnectionProvider.getConnection(UserSuppliedConnectionProvider.java:32)
at net.sf.hibernate.impl.BatcherImpl.openConnection(BatcherImpl.java:289)

My properties file look like the following:
hibernate.connection.driver_class=in.co.daffodil.db.rmi.RmiDaffodilDBDriver
hibernate.connection.url=jdbc:daffodilDB://localhost:3456/Hibernate
hibernate.connection.username=daffodil
hibernate.connection.password=daffodil
hibernate.dialect=net.sf.hibernate.dialect.DaffodilDBDialect
hibernate.c3p0.min_size=5
hibernate.c3p0.max_size=20
hibernate.c3p0.timeout=300
hibernate.c3p0.max_statements=50
hibernate.c3p0.idle_test_period=3000

I'm able to obtain a connection from the database using JDBC or through DBVisualizer with the same url, user and password.

Anybody have any thoughts on the subject?

Found the problem. It was something completely else any too silly to mention.
