I just started learning Java.
I need to make a chat messenger project in java for my college project.
The messenger should be able to send messages,add persons to chat and to see who is online.
I have only one month of time for my project.
Please tell me how to start and what tutorials to follow so that i will be able to make this project on my own.
(I know c++ and can put my full attention towards this project)
Reply soon.
Thanks

If you search DaniWeb for Java Chat you will find lots of discussions abou this topic, including the kinds of problems people encounter and how they can be solved.

But the one thing you are certain to need is a multi-threaded server using Sockets. This tutorial is excellent...

hmm, tbh I'd go a few rungs up the ladder and use something like JMS to handle most of the nitty gritty details for me...

First you say:

directly followed by:

very counter productive. you would do better to first learn Java.
