A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation. Having a specification ensures interoperability of Java programs across different implementations so that program authors using the Java Development Kit (JDK) need not worry about idiosyncrasies of the underlying hardware platform.
The OSGi Alliance, formerly known as the Open Services Gateway initiative, is an open standards organization founded in March 1999 that originally specified and continues to maintain the OSGi standard.
Jakarta Enterprise Beans is one of several Java APIs for modular construction of enterprise software. EJB is a server-side software component that encapsulates business logic of an application. An EJB web container provides a runtime environment for web related software components, including computer security, Java servlet lifecycle management, transaction processing, and other web services. The EJB specification is a subset of the Java EE specification.
Java Platform, Micro Edition or Java ME is a computing platform for development and deployment of portable code for embedded and mobile devices. Java ME was formerly known as Java 2 Platform, Micro Edition or J2ME.
The Java Community Process (JCP), established in 1998, is a formalized mechanism that allows interested parties to develop standard technical specifications for Java technology. Anyone can become a JCP Member by filling a form available at the JCP website. JCP membership for organizations and commercial entities requires annual fees – but is free for individuals.
Java Management Extensions (JMX) is a Java technology that supplies tools for managing and monitoring applications, system objects, devices and service-oriented networks. Those resources are represented by objects called MBeans. In the API, classes can be dynamically loaded and instantiated. Managing and monitoring applications can be designed and developed using the Java Dynamic Management Kit.
Web Services for Remote Portlets (WSRP) is an OASIS-approved network protocol standard designed for communications with remote portlets.
Java APIs for Bluetooth Wireless Technology (JABWT) is a J2ME specification for APIs that allows Java MIDlets running on embedded devices such as mobile phones to use Bluetooth for short-range wireless communication. JABWT was developed as JSR-82 under the Java Community Process.
The Java Portlet Specification defines a contract between the portlet container and portlets and provides a convenient programming model for Java portlet developers.
Java Business Integration (JBI) is a specification developed under the Java Community Process (JCP) for an approach to implementing a service-oriented architecture (SOA). The JCP reference is JSR 208 for JBI 1.0 and JSR 312 for JBI 2.0. JSR 312 was removed from the JCP balloting process on 17 Dec, 2010 by the submitters without being accepted.
Jiro is the registered name used by Sun Microsystems for an extension to Java and Jini.
A Technology Compatibility Kit (TCK) is a suite of tests that at least nominally checks a particular alleged implementation of a Java Specification Request (JSR) for compliance. It is one of the three required pieces for a ratified JSR in the Java Community Process, which are:
Real time Java is a catch-all term for a combination of technologies that enables programmers to write programs that meet the demands of real-time systems in the Java programming language.
Apache MyFaces is an Apache Software Foundation project that creates and maintains an open-source JavaServer Faces implementation, along with several libraries of JSF components that can be deployed on the core implementation. The project is divided into several sub-projects:
OpenJPA is an open source implementation of the Java Persistence API specification. It is an object-relational mapping (ORM) solution for the Java language, which simplifies storing objects in databases. It is open-source software distributed under the Apache License 2.0.
JSR 48 Java WBEM API Specification is a Java Specification Request developed under the Java Community Process. It specifies the Java language binding of the DMTF Common Information Model/Web-Based Enterprise Management standards. The JSR 48 Expert Group has completed the public review in 2006 and is now on the way to create a Technology Compatibility Kit in order to finalize the standard. The API can be regarded as stable.
The Swing Application Framework is a Java specification for a simple application framework for Swing applications, with a graphical user interface (GUI) in computer software. It defines infrastructure common to most desktop applications, making Swing applications easier to create. It has now been withdrawn.
JBoss Tools is a set of Eclipse plugins and features designed to help JBoss and JavaEE developers develop applications. It is an umbrella project for the JBoss developed plugins that will make it into JBoss Developer Studio.
DataNucleus is an open source project which provides software products around data management in Java. The DataNucleus project started in 2008.
The JBoss Enterprise Application Platform is a subscription-based/open-source Java EE-based application server runtime platform used for building, deploying, and hosting highly-transactional Java applications and services developed and maintained by Red Hat. The JBoss Enterprise Application Platform is part of Red Hat's Enterprise Middleware portfolio of software. Because it is Java-based, the JBoss application server operates across platforms; it is usable on any operating system that supports Java. JBoss Enterprise Application Platform was originally called JBoss and was developed by the homonym company JBoss, acquired by Red Hat in 2006
