Jini
Jini (), also called Apache River, is a network architecture for the construction of distributed systems in the form of modular co-operating services. JavaSpaces is a part of the Jini. Originally developed by Sun Microsystems, Jini was released under the Apache License 2.0. Responsibility for Jini has been transferred to Apache under the project name "River". History Sun Microsystems introduced Jini in July 1998. In November 1998, Sun announced that there were some firms supporting Jini. The Jini team at Sun has always stated that ''Jini'' is not an acronym. Ken Arnold has joked that it means "Jini Is Not Initials", making it a recursive anti-acronym, but it has always been just ''Jini''. The word 'jini' means "the devil" in Swahili; this is borrowed from the Arabic word for a mythological spirit, originated from the Latin ''genius'', which is also the origin of the English word 'genie'. Jini provides the infrastructure for the Service-object-oriented architecture (SOOA). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recursive Acronym
A recursive acronym is an acronym that refers to itself, and appears most frequently in computer programming. The term was first used in print in 1979 in Douglas Hofstadter's book '' Gödel, Escher, Bach: An Eternal Golden Braid'', in which Hofstadter invents the acronym GOD, meaning "GOD Over Djinn", to help explain infinite series, and describes it as a recursive acronym. Other references followed, however the concept was used as early as 1968 in John Brunner's science fiction novel ''Stand on Zanzibar''. In the story, the acronym EPT (Education for Particular Task) later morphed into "Eptification for Particular Task". Recursive acronyms typically form backwardly: either an existing ordinary acronym is given a new explanation of what the letters stand for, or a name is turned into an acronym by giving the letters an explanation of what they stand for, in each case with the first letter standing recursively for the whole acronym.

Tuple Space
A tuple space is an implementation of the associative memory paradigm for parallel/distributed computing. It provides a repository of tuples that can be accessed concurrently. As an illustrative example, consider that there are a group of processors that produce pieces of data and a group of processors that use the data. Producers post their data as tuples in the space, and the consumers then retrieve data from the space that match a certain pattern. This is also known as the blackboard metaphor. Tuple space may be thought as a form of distributed shared memory. Tuple spaces were the theoretical underpinning of the Linda language developed by David Gelernter and Nicholas Carriero at Yale University in 1986. Implementations of tuple spaces have also been developed for Java (JavaSpaces), Lisp, Lua, Prolog, Python, Ruby, Smalltalk, Tcl, and the .NET Framework. Object Spaces Object Spaces is a paradigm for development of distributed computing applications. It is characterized by t ...

Ken Arnold
Kenneth Cutts Richard Cabot Arnold (born 1958) is an American computer programmer well known as one of the developers of the 1980s dungeon-crawling video game '' Rogue'', for his contributions to the original Berkeley (BSD) distribution of Unix, for his books and articles about C and C++ (e.g. his 1980s–1990s ''Unix Review'' column, "''The C Advisor''"), and his high-profile work on the Java platform. At Berkeley Arnold attended the University of California, Berkeley, after having worked at Lawrence Berkeley National Laboratory computer labs for a year, receiving his A.B. in computer science in 1985. At Berkeley, he was president of the Berkeley Computer Club and of the Computer Science Undergraduates Association, and made many contributions to the 2BSD and 4BSD Berkeley Unix distributions, including: * curses and termcap: a hardware-independent library for controlling cursor movement, screen editing, and window creation on ASCII display terminals, based on termcap (based ...

Java Remote Method Invocation
In computing, the Java Remote Method Invocation (Java RMI) is a Java API that performs remote method invocation, the object-oriented equivalent of remote procedure calls (RPC), with support for direct transfer of serialized Java classes and distributed garbage-collection. The original implementation depends on Java Virtual Machine (JVM) class-representation mechanisms and it thus only supports making calls from one JVM to another. The protocol underlying this Java-only implementation is known as Java Remote Method Protocol (JRMP). In order to support code running in a non-JVM context, programmers later developed a CORBA version. Usage of the term RMI may denote solely the programming interface or may signify both the API and JRMP, IIOP, or another implementation, whereas the term RMI-IIOP (read: RMI over IIOP) specifically denotes the RMI interface delegating most of the functionality to the supporting CORBA implementation. The basic idea of Java RMI, the distributed garbage-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Management Extensions
Java Management Extensions (JMX) is a Java technology that supplies tools for managing and monitoring applications, system objects, devices (such as printers) and service-oriented networks. Those resources are represented by objects called MBeans (for '' Managed Bean''). 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. JSR 003 of the Java Community Process defined JMX 1.0, 1.1 and 1.2. JMX 2.0 was being developed under JSR 255, but this JSR was subsequently withdrawn. The JMX Remote API 1.0 for remote management and monitoring is specified by JSR 160. An extension of the JMX Remote API for Web Services was being developed under JSR 262. Adopted early on by the J2EE community, JMX has been a part of J2SE since version 5.0. "JMX" is a trademark of Oracle Corporation. Architecture JMX uses a three-level architecture: # The ''Probe'' level – also called the ...

Service Location Protocol
The Service Location Protocol (SLP, srvloc) is a service discovery protocol that allows computers and other devices to find services in a local area network without prior configuration. SLP has been designed to scale from small, unmanaged networks to large enterprise networks. It has been defined in RFC 2608 and RFC 3224 as standards track document. Overview SLP is used by devices to announce ''services'' on a local network. Each service must have a URL that is used to locate the service. Additionally it may have an unlimited number of name/value pairs, called ''attributes''. Each device must always be in one or more ''scopes''. Scopes are simple strings and are used to group services, comparable to the ''network neighborhood'' in other systems. A device cannot see services that are in different scopes. The URL of a printer could look like: service:printer:lpr://myprinter/myqueue This URL describes a queue called "myqueue" on a printer with the host name "myprinter". The protoc ...

Java Platform
Java is a set of computer software and specifications developed by James Gosling at Sun Microsystems, which was later acquired by the Oracle Corporation, that provides a system for developing application software and deploying it in a cross-platform computing environment. Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers. Java applets, which are less common than standalone Java applications, were commonly run in secure, sandboxed environments to provide many features of native applications through being embedded in HTML pages. Writing in the Java programming language is the primary way to produce code that will be deployed as byte code in a Java virtual machine (JVM); byte code compilers are also available for other languages, including Ada, JavaScript, Python, and Ruby. In addition, several languages have been designed to run natively on the JVM, including Clojure, Groovy, and Scala. J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Common Object Request Broker Architecture
The Common Object Request Broker Architecture (CORBA) is a standard defined by the Object Management Group (OMG) designed to facilitate the communication of systems that are deployed on diverse platforms. CORBA enables collaboration between systems on different operating systems, programming languages, and computing hardware. CORBA uses an object-oriented model although the systems that use the CORBA do not have to be object-oriented. CORBA is an example of the distributed object paradigm. Overview CORBA enables communication between software written in different languages and running on different computers. Implementation details from specific operating systems, programming languages, and hardware platforms are all removed from the responsibility of developers who use CORBA. CORBA normalizes the method-call semantics between application objects residing either in the same address-space (application) or in remote address-spaces (same host, or remote host on a network).

Devices Profile For Web Services
The Devices Profile for Web Services (DPWS) defines a minimal set of implementation constraints to enable secure web service messaging, discovery, description, and eventing on resource-constrained devices. Its objectives are similar to those of Universal Plug and Play (UPnP) but, in addition, DPWS is fully aligned with Web Services technology and includes numerous extension points allowing for seamless integration of device-provided services in enterprise-wide application scenarios. DPWS standardization The DPWS specification was initially published in May 2004 and was submitted for standardization to OASIS in July 2008. DPWS 1.1 was approved as OASIS Standard together with WS-Discovery 1.1 and SOAP-over-UDP 1.1 on June 30, 2009. DPWS defines an architecture in which devices run two types of services: ''hosting services'' and ''hosted services''. Hosting services are directly associated with a device, and play an important part in the device discovery process. Hosted services ar ...
