I use Hibernate 3.1.2 woth DB2 8.2 and Java 5

I have create table name Hibernate. wich stored the Hibernate-IDs
This Table have one row with the name next_value and is a Integer-field.

In the Mappings of the Tables I use the hilo Generatior to generate IDs

But, when I start my application I become the following Error Message:

08:53:11,062 DEBUG ConnectionManager:369 - connection already null in cleanup : no action
08:53:11,062 ERROR [schulung]:257 - Servlet.service() for servlet schulung threw exception

could not read a hi value - you need to populate the table:

What is to do to find the Problem?
HIBERNATE-Table is a special Hibernate-Table and haven't a mapping.
I think the Table-Creation is not ok, so Hibernate cant use it.
What is to do to create this Table right?

Thanks for ouer help
