After ". net Resources for performing MSN/IM/Messenger operations", I sorted out some Java IM resources for ease of query.

1,Java IM

2,Java Instant Messenger

Java Instant Messenger (or JIM) is an application to allow instant messaging over a network. JIM does not have a centralized server. instead, users run the server on one of the computers on the network and other users connect to that server.

Spark is an open-source, cross-platform IM client. Its features support group chat, telephone integration, and powerful security performance. If the enterprise deploys IM using Openfire + Spark, it is the best combination.

6,Source code similar to QQ chat software for JAVA (with design documents)
Author: in fact, there are a lot of software such as QQ chat, but basically there is no public source code, but also only provide software clients, some software such as ICQ although the server but not open source code. I really want to know its operating mechanism and want to understand what it is, so I tried to make a simple interface, although it is not as complex and friendly as the formal company's, but at least it can give you some inspiration, which is helpful for learning.
