Client/Server with CORBA

[Eimo]

Hi,

I'm doing a client/server program that can calculate + 4 6 or - 6 4. I wanted to ask how can I read a line with spaces and return the result to the client????

If anyone can help please.... I'm trying to run a Client/Server program using CORBA and when I put this line in the command:
java CalServer -ORBInitialPort 2500
It gives me this error:

Remove all the spaces from the string and do necessary conversions before do the calculations.
