Pretty simple stuff, except for two key differences between this class and a generic
container class for data: the declaration imports java.rmi , and each of the accessors and
mutators can throw java.rmi.RemoteException . When implementing a remotable class, all
of its methods may throw java.rmi.RemoteException , because the class implementation
may actually be a remote stub provided by the IXC registry and may be unable to com-
municate with the actual instance of the class.
As I previously stated, the entire java.rmi class hierarchy is not available to Xlets
running atop the PBP. Instead, the PBP requires only the following RMI classes:
• java.rmi.Remote : Used to indicate a remotable class
• java.rmi.AccessException : Thrown to indicate that the caller of a remote object
does not have permission to perform the requested action
• java.rmi.AlreadyBoundException : Thrown if you attempt to bind an object to the
registry to a name that has already been bound to another object
