Spring provides a SockJS-less Websocket endpoint at `ws://host:port/socketentry/websocket` without using the SockJS bucket and session URL componets: `ws://host:port/socketentry/{bucket}/{session}/websocket`
jWebSocket is a pure Java/JavaScript high speed bidirectional communication solution for the Web - secure, reliable and fast. Provides easy integration into existing Tomcat web applications.
BinaryJS is a lightweight framework that utilizes websockets to send, stream, and pipe binary data bidirectionally between browser javascript and Node.js.
