Concurrency Utilities for Java EE provides a simple, standardized API for using concurrency from application components without compromising container integrity while still preserving the Java EE platform's fundamental benefits.
Java Transaction API (JTA) specifies standard Java interfaces between a transaction manager and the parties involved in a distributed transaction system: the resource manager, the application server, and the transactional applications.
The Java EE security provides a set of required security functionalities including authentication, authorization, data integrity, and transport security.
The JavaBeans Activation Framework (JAF) is a standard extension to the Java platform that lets you take advantage of standard services to: determine the type of an arbitrary piece of data; encapsulate access to it; discover the operations available on it; and instantiate the appropriate bean to perform the operation(s).
The JavaMail API provides a platform-independent and protocol-independent framework to build mail and messaging applications. The JavaMail API is available as an optional package for use with the Java SE platform and is also included in the Java EE platform.
Expression Language (also referred to as the EL) provides an important mechanism for enabling the presentation layer (web pages) to communicate with the application logic (managed beans). The EL is used by several JavaEE technologies, such as JavaServer Faces technology, JavaServer Pages (JSP) technology, and Contexts and Dependency Injection for Java EE (CDI). The EL can also be used in stand-alone environments.
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
