I have some troubles getting Sun Java Studio Creator & Sun Java Application Server to work with
PostgreSQL.

Trying different syntaxes for the SQL statement (schema or no schema) in the session bean
I get either the error: "No columns in table: pmh.tablename" or
"Cannot change transaction isolation level in the middle of a transaction"
when trying to delete, insert or update rows. Selecting is ok.

The application works fine when using an Apache Derby database, so the problem is related to PostgreSQL

I can see several postings on other mailing lists with the same problem, but haven's found any solution.

Do anyone of you know what I can do ?


Thanks,
Poul
