what can I use for a messenger server in Java

instead of java socket, what else I can use for a messenger server in Java.

My goa开发者_StackOverflow中文版l is to maintain more client.I know a little about RMI. But I'm not sure what should I use. I want to maintain more than 100,000 client at a time.

Without more information I would suggest JMS.

100,000 client is a lot. Is this concurrent clients or registered clients?

Is this on the internet, or internal network?

It looks like you need JMS with clustered broker (I'd recommend HornetQ).

You can also use Apache ActivemQ, its easy to get started with. Find more about ActivemQ here

I don't really know what you're asking so I'm sorry if this is a terrible answer but I'll do my best. If you have a deadline to meet I would use a well coded library like JMS, however I haven't ever looked at the source code but I'd say its a safe bet it uses Sockets. If there is another way to make the type of connection you're trying to I don't know what it is.

If this is for personal use or educational purposes I would make your own, that's how I learned. I studied some source code I found and java2s.com for a chat program then made my own implementation. The program I made is more like an instant messenger than a chat, I did it in Java because it's easy to programs cross-platform and I think that's important for something like an instant messenger.

If you'd like to take a look at the source code send me your e-mail address. My e-mail address is kevin.bigler3@gmail.com. Good luck, sorry I couldn't be more help.
