Send Data to Specific Thread

Could you describe what it is you're trying to accomplish with this? What is the overall problem you're trying to solve?

I'm making an AWT based chat application. It isn't a channel based application, it's p2p (so kinda like a one-on-one type of thing). When the user opens a chat with someone a new window (or frame) is started in a new thread and a reference is put in a Vector so i can kepp track of them all. I need to know how to send data the certain threads when the client receives data from the server. Or i need to be able to tell the specific thread to execute a certain method to retreive the data from somewhere. Is there any way of doing this?

It sounds like you need to solve two different problems. One is a connection to the server, and the other is the P2P connection between chat participants. If the P2P part is only for 1:1, then it is really easy, if it is for 1:n it becomes a little bit trickier. Is my assumption correct?

Well it is 1:n, but what do you suggest?

I would create a class which handles client requests to the server (which it sounds like you pretty much have right now). Then you would need to create a P2PClient which is capable of communicating with another P2PClient. Are you using TCP or UDP for the network communication?

I'm using TCP, but unsigned applets can only connect to the server that they were spawned off of... so the server has to handle all networking between clients.
