RemoteRuntimeException

Question

Help, please.
I'm running WebLogic 5.1.0, sp3 on NT.
I haven't tried all the examples, but the beanmanaged client and the ListAll
class seem to work fine.
The problem is with my own client program that is VERY similar to the
ListAll, i.e. it does a listBindings("") and then walks through an
enumeration of Bindings, printing a few details.
ListAll works fine, but mine fails on the first nextElement() call with this
exception:
weblogic.rmi.extensions.RemoteRuntimeException
and this msg:
Undeclared checked exception
Not much help, nothing interesting in the log...so what does it mean?
Thanks,

Thank you, I think this is a step in the right direction...the nested
exception is weblogic.rjvm.PeerGoneException; no message.
Does this mean that somewhere between my calls to
NamingEnumeration.hasMoreElements() and NamingEnumeration.nextElement() that
some peer disappears?
It would appear that a ClassCastException is buried in here somewhere as
well:

So the peer left because it had trouble casting? The code is real simple:
NamingEnumeration nameEnum = ctx.listBindings( "" );
while ( nameEnum.hasMoreElements() )
Binding aBind = (Binding) nameEnum.nextElement();
...give or take some try...catch code

The RemoteRuntimeException contains a nested exception. Check that to
see what's really wrong.
