C++ Java communication

Hello,

I am considering all possible options to use for communication between C++ server application and arbitrary number of Java GUI client applications. Amount of data which i need to transmit is not big, but transfer speed and
especially reliability of communication need to be high!

With regard to needed client-server architecture i would like to know which option(s) will be best to use here.

Can someone give me (or point to) comparing analyze of various options: sockets, JNI, CORBA, pipes...and
list cons and prons and what would be best to use in my case.

Thanks.
