Problem with return cardinality of my Entity-Bean

Hi all,

i'm using Sun Java Studio Enterprise 8.1 and i try to create a EJB CMP Entity-Bean, it's name is Customer. But i become an error during the deploy. By the method findByName(String name) i selected as return cardinality "Many" and become below error. If i select "One" as return cardinality then is this error away.

What is here wrong? Every time when i create an EntityBean i become this error, but just by "Many" return cardinality. Can anyone help me to solve this problem?

thanks

Bean: CustomerBean

Method : public abstract Collection findByName(String) throws FinderException

Section: 10.5.6

Warning: Every finder method except findByPrimaryKey(key) must be associated with a query element in the deployment descriptor.
