Networking in Java

Hi all,
Just wonder if any of you know how to transfer file from server to client application using JDK 1.3.1? Do we use sockets to establish connection and later use writeByte() from the DataOutputStream? Or is there a simpler and more effective way to do it? Like using datagram or stuff like that?

nope.. don't use datagram...
Datagram is for multicast/broadcast purpose, meaning, the receiver is not only one, but a group, and datagram uses UDP, it means there is no guarantee that the packet you send arrived at destination or arrived in sequence (if u send a b c d, the receiver may receive a b d c).
You can use TCP, try to learn ServerSocket and Socket. Yup, you have to send bytes, so, it is depends on who transfer and who will receive. Generally, host which has the file become the server and host which need the file, become the client. So, in server-side, u use ServerSocket, and in client side, u use Socket...

yup use serverSocket and socket, then use the socket.get(Input/Output)Stream to get the io stream, afterward u can try to use ByteArray(Input/Output)Stream or Data(Input/Output)Stream both are good for data transfer for files. try to play around with the streams to find the best combination for your thingy
