Eclipse LSPHub defines a data model for a kind of ubiquitous plug-ins format for all editors/IDEs. It focuses on describing artifacts that implements platform/tools indenpendent language services like LSP.
The data model defines the concept of an Extension which is a logical group of Contributions. A contribution provides support for editing file of given types (typing is being made via UTI).
JSR- 343: The Java Message Service (JMS) API is a Java Message Oriented Middleware API for sending messages between two or more clients. It is a programming model to handle the producer-consumer messaging problem.
Java API for WebSocket (JSR-356), 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.
JAX-RS: Java API for RESTful Web Services (JAX-RS) is a Java programming language API spec that provides support in creating web services according to the Representational State Transfer (REST) architectural pattern.
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.
Eclipse Open Message Queue (OpenMQ) is a complete message-oriented middleware platform, offering high quality, enterprise-ready messaging.
OpenMQ is included in GlassFish.
Writing scalable server applications in the Java™ programming language has always been difficult. Before the advent of the Java New I/O API (NIO), thread management issues made it impossible for a server to scale to thousands of users. The Eclipse Grizzly NIO framework has been designed to help developers to take advantage of the Java™ NIO API.
Eclipse Mojarra is an implementation for the JavaServer Faces specification (JSR-372). JavaServer Faces (JSF) is a Java specification for building component-based user interfaces for web applications. It is also a MVC web framework that simplifies construction of user interfaces (UI) for server-based applications by using reusable UI components in a page.
Mojarra is included in GlassFish.
Eclipse Project for JSON-P is a Java API to process (e.g. parse, generate, transform and query) JSON documents. It produces and consumes JSON in a streaming fashion (similar to StAX API for XML) and allows to build a Java object model for JSON using API classes (similar to DOM API for XML).
