Hi Kevin
Thanks for the information, I have added the following value to my
persistence.xml file:
<property name="openjpa.jdbc.DBDictionary"
value="hsql(useSchemaName=true)"/>
This will generate tables in the specified schema as expected.
I still think that this option should be true by default. If this is
more dependant on the databse than the DBDictionary then it could be
more of a problem.
Is there a way of getting this added to the documentation?

David
