Use long double only on C++ Server/client with the same types implementation (be careful of systems OS)
Do not use unsigned types with a
C++ Server/JAVA Client
Key only attributes and methods
which are used by the Server and Client, the entire real objects can
have internal attributes/methods only used by the Server.
Use mutexes for real time
applications, or for multi Clients applications sharing Server
You can use JAVA Client
You can use WxWidgets for C++ Client
Standard default ports are 1048
(java orbd) and 2809
Some softwares use them, try
others if Naming Service does not start (1053)
