David,
<vendor>
Jim's comment about Dynamic Proxies marshaling not being supported
by a vendor's ORB (ours) should not have been read to suggest that
Dynamic Proxies are unsupportable in CORBA-based servers. It is
simply that Dynamic Proxies cannot be marshaled with VisiBroker
for Java 4.1, which is used by IAS 4.1. The fact that this does not
work is a bug in VBJ; it is not a limitation of CORBA and/or IIOP.
And the fact that it does not work with Sun's IIOP implementation
either is a coincidence. Again, "CORBA" (meaning Objects-by-Value
and IIOP) supports this capability. Aparantly, there is some
peculiarity in this capability which is tripping up both of us.
