I wonder if anyone could shed some light on what the following exception means and why I might be getting it. I'm running jboss 2.4.3 – the latest Opta SQLServer driver. Any help is greatly appreciated.

It seems to be thrown when a Stateless SB using "NotSupported" tranx invokes a find method on a BMP Enity bean ("ejbFindByLoginCredentials" method).

Thx
