JavaServer Pages Standard Tag Library (JSTL) encapsulates as simple tags the core functionality common to many Web applications. JSTL has support for common, structural tasks such as iteration and conditionals, tags for manipulating XML documents, internationalization tags, and SQL tags. It also provides a framework for integrating existing custom tags with JSTL tags.
JSON-B is a standard binding layer for converting Java objects to/from JSON messages. It defines a default mapping algorithm for converting existing Java classes to JSON, while enabling developers to customize the mapping process through the use of Java annotations.
Through HIP, localised processing or preperation of data is intended to reduce the connectivity and central processing requirements within IOT - much like the contemporary Fog computing paradigm, but without the need for sophisticated edge computing solutions.
Base Device messages enable core functionality supports each "thing" in a deployment, with additional roles being configured through Configuration messages, and functionality enabled through Handler messages and files
Eclipse Corrosion provides development tools for Rust and Cargo inside the Eclipse IDE.
LocationTech RasterFrames brings the power of Spark DataFrames to geospatial raster data, empowered by the map algebra and tile layer operations of GeoTrellis. The underlying purpose of RasterFrames is to allow data scientists and software developers to process and analyze geospatial-temporal raster data with the same flexibility and ease as any other Spark Catalyst data type. At its core is a user-defined type (UDT) called TileUDT, which encodes a GeoTrellis Tile in a form the Spark Catalyst engine can process.
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).
Eclipse Krazo is an implementation of action-based MVC specifiec by MVC 1.0 (JSR-371). It builds on top of JAX-RS and currently contains support for RESTEasy, Jersey and CXF with a well-defined SPI for other imlementations.
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.
