Introduction
In one of our organization meeting we decided to embed simple chat module in all our apps developments including IOS, Android and Windows.
For Java lovers oracle MAF have proven to be a complete, stable framework and tools to develop cross platform enterprise mobile application. Its apparently easy to learn without much complications or difficult learning curves. With Oracle MAF you have lots of options to choose from to build a chat system as whatsapp or facebook in days. This is a very basic chat with very few lines of code as shown below.
