ClassCastException in all finder methods != findByPK

[Horaci Macias]

I'm testing my EJB finder methods and I've problems in all of them except findByPK. A exception is thrown when I try to cast the Enumeration return findBy... to my EJB's remote interface.
It's strange because if I debug my ejbFindBy... it works fine; the return Enumeration has all PK that have to be there, but if I try to cast to my EJB's remote interface after calling findBy... (in home interface) it crashes like this:
java.lang.ClassCastException: org.omg.stub.javax.ejb._EJBObject_Stub
If used Class.isAssignableFrom(Class) and the objects in return Enumeration aren't assignable to my remote interface nor my ejb class nor to my home interface ?!
I'm using WAS 3.5 Advanced Edition.
Could anyone help me please ?
Thank you,

Yeah, this is a bug (actually, it's an "alternate interpretation of a vague area of the EJB 1.0 spec" -- in other words a bug).
What you need to do is do a javax.rmi.PortableRemoteObject.narrow() on each of the objects returned like so:
Enumeration enum = myFooHome.findAllFoos(...);
while (enum.hasMoreElements()) {
Object ref = enum.nextElement();
FooEJB ejb = (FooEJB) javax.rmi.PortableRemoteObject.narrow(ref, FooEJB.class);
// you can now use the ejb object...
}

Thank you again Kyle.
The solution you gave me makes everything work fine, the only problem I had is that when you said:
FooEJB ejb = (FooEJB) javax.rmi.PortableRemoteObject.narrow(ref, FooEJB.class);
I thought you meant FooEJB -> EJB class, and it did'nt work at first (another ClassCastException in narrow()). Later I try to use my remote interface instead of my ejb class and narrow() worked fine.
