How to implement Web chat

If you don't have a concept with web chat, the best practice might be: Openfire+jsjac

OpenFire is a Java-made open source XMPP server, and Jsjac is an open-source, web-version XMPP client made by JavaScript.

1. Open the HTTP binding and Bosh in the admin interface of OpenFire and open "in-band account Registration".
2. Copy the Jsjac simpleclient.html and jsjac.js to the Resources/spank directory of OpenFire
3. If your OpenFire HTTP port is open on port 9090, then access: http://192.168.0.100:9090/simpleclient.html
4. On the page HTTP base fill in: http://192.168.0.100:9090/http-bind/, write a random account password, tick "register new account", you can register and log in.
5. Do not check "register new account" When you log in later, so as not to repeat the registration.

It's so easy to build a web chat system.

PS: If you need to do follow-up development, then resource and mechanism such as XMPP-related knowledge is needed.
