[Springframework-developer] RmiServiceExporter Bug?

[Dongdong Z. <dz...@ur...>]

Hi

I am trying to use the transparent RMI package, and found a
problem with RmiServiceExporter.

In afterPropertiesSet method,
LocateRegistry.getRegistry(this.port) is used to detect if the
registry is running or not, but getRegistry does not throw
RemoteException if no registry running, here is a quote from
javadoc for LocateRegistry

"Note that a getRegistry call does not actually make a
connection to the remote host. It simply creates a local
reference to the remote registry and will succeed even if no
registry is running on the remote host. Therefore, a subsequent
method invocation to a remote registry returned as a result of
this method may fail"

so even if no registry running, getRegistry will return some
value, and subsequent rebind will fail. 

if we call list method on the registry returned by getRegistry,
it will throw RemoteException if no registry running.

Regards
