(a) There is no such thing as multicast over TCP.(b) TCP sockets already have streams.So what is the problem exactly?ejpa at 2007-7-12 19:21:31 >

No dude i know they have streams but where to store the corresponding socket and its stream so that i can write to that particular socket using the same stream?Do i need to use a vector or a hashtable?vdga at 2007-7-12 19:21:31 >

We were supposed to guess that?Getting a bit sick of this guessing game. This is Data Structures 101 and you haven't provided enough information to solve it, not that you should need any help frankly.ejpa at 2007-7-12 19:21:31 >

Hi,
First of all, are you sure you have enough knowledge to build such application? are you sure you don't need to check some tutorials first?
I have read some books on networking / sockets and java in general and still do not feel I have all the required knowledge to answer this post. However this is my quess.
Personally I think that your socket connection should be wrapped in some type of handler object. These handler objects should then be stored in some type of collection (like a pool). The when you need to send a message all you have to do is loop in this collection and send the message to each client connection!!
