[jBoss-User] Finder Methods in CMP Beans

[Peter Shillan]

Hi Folks,

I have a query about Finder method generation in CMP beans. I have copied an
example customer bean from "Mastering Enterprise JavaBeans" and it uses CMP.
The book assures me that

 *   @finder Collection findByExpensiveProduct( double minPrice )
 *   @finder Collection findCheapProducts( double maxPrice )

will be generated, but they're not cause they don't match any fields in the
object and I agree... how on Earth could a container generate methods for
these finders? Can I simply implement them myself as if they were BMP?

Thanks in advance,

Peter.
