I'm using MySQL with a table using an Integer PK field with the autoincrement
attribute on. In this code the PK is available after the ejbCreate method
because of the <entity-command name="mysql-get-generated-keys"/> and
<auto-increment/> elements.
I'm using XDoclet partly, only for generating the interfaces.
