Your ejbFindBySectorId returns IdSectorPKs. The container transforms those
to instances of the remote inteface (IdSector??)
Try casting to the remote interface.

Hi, I have the next function (see below)
It returns an Enumeration of IdSectorPK. But we know that at the ckient
part,
we have to cast. the problem is that when i cast, i got an error:
java.lang.ClassCastException: $Proxy1
Why can't i cast to IdSectorPK???????????????????
Please help.

client code
===========
IdSectorHome home = (IdSectorHome) PortableRemoteObject.narrow (ref3,
IdSectorHome.class);
Enumaration enum = home.findBySectorId("XX");
while(theEnum.hasMoreElements()) {
Object obj = theEnum.nextElement();
System.out.println(" ID: " + obj);
//System.out.println(" CLASS: " + obj.getClass());
IdSectorPK pro = (IdSectorPK) obj;//this line build an error
