1) An RMI-IIOP client cannot necessarily access all existing CORBA objects It is related to the IDL mapping between CORBA object'IDL and RMI-IIOP java interface. Sometimes, you cannot have a corresponding mapping with old existing CORBA Object...a solution is JavaIDL. You can obtain a correct mapping when you design a new distributed RMI-IIOP object, you can generate the IDL from the the RMI-IIOP interface and you can implement a Corba object from these IDL. So, the RMI-IIOP client won't have any problems to access the Corba object. 2) Can I operate RMI-IIOP through a Firewall? it depends of the Firewall filtering configuration. If the firewall lets only HTTP, HTTPS go through.....IIOP won't work !! you have to use some http tunnelling solution..... These question has been asked a the exam. herve Thanx, Vidya[/B]

The answer is Yes you can operate RMI-IIOP through the firewall. But as said above this depends if the firewall is configured to open one port to allow the RMI-IIOP traffic to go through. Normally HTTP and HTTPS ports are available through any firewall. However you have to configure the firewall to allow any other protocol through. Rahul.
Suresh- Thanks for the link. Interesting stuff. I have another question: it seems that the overall design is to use HTTP protocol to mimic HTTP so as to get through the firewall. Once that is done, I assume I can do anything underneath? RMI, etc? thanks, max
