NullPointerException creating connection

[Mark George]

Hi.

I'm having some trouble creating a connection.  I have tried with an existing hibernate project, and a brand new clean (empty - with src and classes folders)  project.

Each time the same result:

!ENTRY org.eclipse.ui 4 4 Feb 09, 2004 00:07:57.490
!MESSAGE Unhandled event loop exception
!ENTRY org.eclipse.ui 4 0 Feb 09, 2004 00:07:57.491

The hibernator log gives nothing other than the ignored output warning.

I am using Firebird with the Interbase dialect.

Here's the connection details I've been using:

URL :jdbc:firebirdsql:localhost/3050:/home/mark/data/researcher/database/researcher.fdb
Driver Class: org.firebirdsql.jdbc.FBDriver
Dialect: net.sf.hibernate.dialect.InterbaseDialect
Driver Filename: /some-path/firebirdsql-full.jar

Any ideas?

TIA

Mark

Forgot to say that I am using Eclipse 3M6 with hibernator 0.96 and Blackdown Java 1.4.1
