JSR 356, Java API for WebSocket, specifies the API that Java developers can use when they want to integrate WebSockets into their applications—both on the server side as well as on the Java client side. Every implementation of the WebSocket protocol that claims to be compliant with JSR 356 must implement this API.

… This chapter describes the Java API for WebSocket (JSR 356), which provides support for creating WebSocket applications. WebSocket is an application protocol that provides full-duplex communications between two peers over the TCP protocol. The next version of JSF, 2.3 comes with the support of the WebSocket protocol.
