Smack

Smack was developed as an open source extensible messaging and presence protocol client library that is aimed at helping users embed XMPP functionality into their own applications. Through its extensive library and optional XEP extensions, the application will allow people to implement it into their utilities and design full XMPP clients packages or basic messaging protocols.
The application works by communicating with the XMPP servers in realtime, in order to achieve the instant messaging and group chat connection. Using the provided programming interface, one will be able to send text messages by writing the corresponding code lines.
Constructed using the Java programming language, its library can be easily embedded into Java-compatible applications. The application will deploy its library as separate JAR files that are meant to provide increased control and flexibility in the features entailed by the application.
In order to enable the application, one will have to run through a two-step initialization process. The first one implies initializing the system properties, which are accessible through the SmackConfiguration class. The second one will call and enable all the classes required to be active at start-up, with the SmackInitializer class.
Controlling the different tools is done by running the corresponding command lines and the library’s JAR files provide core XMPP functionality, XMPPTCP connectivity, multi-user chat, file transfer, user search, etc. Support for legacy extensions that are defined by the XMPP Standards Foundation is offered and the BOSH (XEP-0124) code is also provided.System requirementsJava 7 or higher.
