I know in the entity bean, the create() and findByPrimaryKey() methods in the home interface will always return the EJBObject reference. It can't return other than EJBObject reference.

I am also having other findBy<name>() and home business methods in the home interface.

I want to know what are the possible return types of findBy<name>() and home business methods in the home interface.

As far my knowledge, the home business methods in the home interface is for returning the raw data to the client,instead of returning the EJBObject reference.

Whether the home business methods in the home interface can't return anything other than raw data?

What are the possible return types of findBy<name>() methods in the home interface.


Why the CMR data field should be either another entity bean's local component interface/ Collection?

Why can't we use another entity bean's remote component interface?
