Program in CORBA which takes a long sentence from client (at least 7 words), passes to the server, server separates out each word and sends back

Write a program in CORBA which takes a long sentence from the client (at least 7 words), passes to the server, server separates out each word and sends them back to client in reverse order, and displays the words on the client side.

Code for Program in CORBA which takes a long sentence from client (at least 7 words), passes to the server, server separates out each word and sends back in Java

// revsent.idl
