Java APIs for Integrated Networks (JAIN) is an activity within the Java Community Process, developing APIs for the creation of telephony (voice and data) services. Originally, JAIN stood for Java APIs for Intelligent Network. The name was later changed to Java APIs for Integrated Networks to reflect the widening scope of the project. The JAIN activity consists of a number of "Expert Groups", each developing a single API specification.
JAIN is part of a general trend to open up service creation in the telephony network so that, by analogy with the Internet, openness should result in a growing number of participants creating services, in turn creating more demand and better, more targeted services.
A major goal of the JAIN APIs is to abstract the underlying network, so that services can be developed independent of network technology, be it traditional PSTN or Next Generation Network.
The JAIN effort has produced around 20 APIs, in various stages of standardization, ranging from Java APIs for specific network protocols, such as SIP and TCAP, to more abstract APIs such as for call control and charging, and even including a non-Java effort for describing telephony services in XML.
There is overlap between JAIN and Parlay/OSA because both address similar problem spaces. However, as originally conceived, JAIN focused on APIs that would make it easier for network operators to develop their own services within the framework of Intelligent Network (IN) protocols. As a consequence, the first JAIN APIs focused on methods for building and interpreting SS7 messages and it was only later that JAIN turned its attention to higher-level methods for call control. Meanwhile, at about the same time JAIN was getting off the ground, work on Parlay began with a focus on APIs to enable development of network services by non-operator third parties.
From around 2001 to 2003, there was an effort to harmonize the not yet standardized JAIN APIs for call control with the comparable and by then standardized Parlay APIs. A number of difficulties were encountered, but perhaps the most serious was not technical but procedural. The Java Community Process requires that a reference implementation be built for every standardized Java API. Parlay does not have this requirement. Not surprisingly, given the effort that would have been needed to build a reference implementation of JAIN call control, the standards community decided, implicitly if not explicitly, that the Parlay call control APIs were adequate and work on JAIN call control faded off. Nonetheless, the work on JAIN call control did have an important impact on Parlay since it helped to drive the definition of an agreed-upon mapping of Parlay to the Java language. (en)
- Java APIs for Integrated Networks (JAIN) ist eine Sammlung von APIs, die auf der Java-Technologie basieren und einen Zugriff auf Telefon- und Datennetze ermöglichen. Die Firma Sun Microsystems hat diese Erweiterung der Java Plattform im Jahr 1998 eingeleitet, um Netzwerkdienste schneller und einfacher entwickeln zu können. Die JAIN Initiative, in der sich verschiedene Anbieter aus dem Telekommunikationsbereich zusammengeschlossen haben, wacht über die Schnittstelle, die durch die Java Specification Requests (JSR) im Java Community Process (JCP) definiert ist.

- JAIN pour Java API for Integrated Networks, est une initiative au sein de la Java Community Process, dont l'objectif est le développement d'interfaces de programmation permettant la création de services de téléphonie (voix et données).
Son objectif est de permettre l'abstraction des réseaux sous jacents, qu'il s'agisse de réseaux sans fils, d'Internet, du réseau téléphonique commuté public, ou d'ATM (Asynchronous Transfer Mode). (fr)
- Le JAIN (Java APIs for Integrated Networks, un tempo chiamate anche Java APIs for Intelligent Network) sono API sviluppate in Java per la creazione di servizi telefonici.
Nell’ambito delle telecomunicazioni la community di Java ha definito un insieme di tecnologie che danno la possibilità di sviluppare rapidamente prodotti e servizi Java per le reti di nuova generazione. JAIN rappresenta una comunità di esperti nell’ambito delle telecomunicazioni nel definire le interfacce Java necessarie per migrare le reti di comunicazioni "proprietarie" verso reti aperte e standardizzate. Le architetture di molti provider di servizi di telecomunicazione sono divenuti molto complessi negli ultimi anni. Questo è dovuto alle varie fusioni di compagnie telefoniche ed all’avvento delle nuove tecnologie di seconda e terza generazione (2.5G e 3G). Le architetture risultano verticalmente integrate ed eterogenee, ma mancano di una interfaccia comune che si basi su uno standard condiviso, oltre al fatto che molte sono strettamente proprietarie. Tutto questo rende estremamente difficile introdurre ed integrare nuovi servizi alla rete.
Il progetto di sviluppo, portato avanti dalla Sun, va sotto il termine di Java Specification Participation Agreement (JSPA) e Java Community Process (JCPTM). Tra le compagnie coinvolte in questo processo troviamo IBM, Motorola, NTT, e Vodafone. (it)
