It's possible have all your LocalHomes extend some BasicEJBLocalHome , but
the EJB spec says that 'The return type for a create<METHOD> method on the
local home interface must be the entity bean's local interface type'.
In your case the create method defined in BasicEJBLocalHome will return
some 'BasicLocalObject' and not the entity bean's local interface type...

Subject: How to extend EJBLocalHome interface?
Hello,
A while ago I posted a message about extending the EJBLocalObject
interface.
But now I wonder if it is possible to extend the EJBLocalHome interface
too?
Mayby I should explain why I want to do this?
I have several LocalEntity beans which are accessed by a SessionFacade
Bean.
The current state I'm in is that I have a create method in the session
facade for each Entitybean. The create methods in the SessionFacade look
more or less the same. It is actually just a copy past operation and change
the LocalHome and LocalObject interfaces.
The data representing an entity bean is assembled in ValueObjects. Each
value object extends a DefaultValueObject.
What I want to do is create an interface BasicEJBLocalHome which extends
EJBLocalHome. In the BasicEJBLocalHome, I define a create method which
takes a valueobject and returns BasicLocalObject interface (this interface
extends the EJBLocalObject interface. this was the question in my previous
post.)
All the LocalHome interfaces of the EJB's extend the BasicEJBLocalHome
interface.
If this is possible, I only have to create one create method in the
SessionFacade taking a DefaultValueObject and a jndiName of the bean.
Lookup the bean and cast it to BasicEJBLocalHome and call the create method
on it. This should then call the create method of the corresponding
beanclass. So my Session facade will look much smaller and it will be much
easier to maintain the code.
I tried this. I used sun's reference implementation to test this but the
verifier in the deploytool fails. It claims the Beanclasses doesn't contain
and ejbCreate method. Although there is one with the same signature as
defined in the BasicEJBLocalHome.
Can somebody tell me if what I wrote is possible? If it is possible, am I
doing something wrong. And if it is not possible, is there an onther
solution to the problem I described?
I hope the describtion is clear enough.
Thanks a lot for your time.
Regards,
Dries De Moor
