This project is created as part of the process of transitioning Oracle Java EE 8 and GlassFish technologies to the Eclipse Foundation as described in The Eclipse Enterprise for Java Project Top Level Project Charter (https://projects.eclipse.org/projects/ee4j/charter).
Eclipse Tyrus is an open source JSR 356 - Java API for WebSocket implementation for easy development of WebSocket applications. WebSocket protocol defined by IETF provides bi-directional communication between the server and the remote host. The pros are mainly the ability to communicate both ways, low latency and small communication overhead. Therefore Tyrus and WebSocket in general are suitable for web applications that require sending a huge volume of relatively small messages like online games or market ticker broadcasting.
The top level EE4J project was created consistent with the direction described in The Eclipse Enterprise for Java Project Top Level Project Charter (https://projects.eclipse.org/projects/ee4j/charter). This project is created under the top level EE4J project as one of Oracle Java EE 8 and GlassFish technologies being transitioned to the Eclipse Foundation.
