Hi!
A simple question: How do I create a CMP entity bean with only one instance?
I need an entity bean that holds the current date as a week and a day number, stored as two columns in a table with only one row. Since there's only one row in the table, I don't need a primary key.
I have created a PK class without any fields, but this doesn't work as JBoss generates invalid SQL: "SELECT FROM currentDate WHERE". This should have been "SELECT week, day FROM currentDate".
How do I do this without resorting to BMP or a dummy PK?
Thanks.
Martin
