Hello,
we can't work with super-interfaces of the home interfaces instead the home
interfaces itselfs. Is this a jBoss bug or is what we try to do against the
EJB 1.1 spec?
we have a group of EB's which have a set of equal business methods. We tried
to define a interface as super-interface for all this EB's. Also we need a
corresponding home interface with a findByPrimaryKey method.
RemoteInterface extends EJBObject {
retType someBusinessMethod();
}
MyEntity extends RemoteInterface {
....
}
and for the home infs:
HomeInterface extends EJBHome {
RemoteInterface findByPrimaryKey(String key);
}
MyHome extends HomeInterface {
MyHome create( ...
}
On the remote side this works but if we call the findByPrimaryKey method
jBoss throws an error.
HomeInterface parentHome =
(HomeInterface)initial.lookup(parentEntity); //thats ok!
RemoteInterface thisParent =
(RemoteInterface)parentHome.findByPrimaryKey(parentId); //but here ocure the
runtime error.
[EACMSession] call DataImpl.getInstance for class 'eacm.ejb.inf.Selection'.
