i use java in socket programming. that was my subject project. its about build up a phonebook server that can be connected from multiple client. its pretty simple tho because socket programming is the basic for network programming. i dont have time to learn advance socket programming language like java rmi or corba.. right now, i work as programmer but more in C++ .Net programming.. i dont know how much we earn for a complete program but there have an offer that i recieve which someone want to pay about Rm800 or ~USD210 for a complete program.
