A web service (WS) is either:
Extensible Messaging and Presence Protocol is an open communication protocol designed for instant messaging (IM), presence information, and contact list maintenance. Based on XML, it enables the near-real-time exchange of structured data between two or more network entities. Designed to be extensible, the protocol offers a multitude of applications beyond traditional IM in the broader realm of message-oriented middleware, including signalling for VoIP, video, file transfer, gaming and other uses.
WebObjects was a Java web application server and a server-based web application framework originally developed by NeXT Software, Inc.
Jakarta Slide is an open-source content management system from the Jakarta project. It is written in Java and implements the WebDAV protocol. Slide is a set of APIs to implement the WebDAV client. Thanks to that, Slide can also be seen as a Content Management Framework. The use of WebDAV, which is a superset of HTTP, makes Slide an ideal candidate for web-based content management. Among the applications of Slide are its use as a file server, in intranet applications, and as an excellent repository for XML both as properties and versioned files for persistence of JavaBeans. It also has an extensible storage mechanism that can be used for Integration and adaptation.
Jakarta Faces, formerly Jakarta Server Faces and JavaServer Faces (JSF) is a Java specification for building component-based user interfaces for web applications and was formalized as a standard through the Java Community Process being part of the Java Platform, Enterprise Edition. It is also an MVC web framework that simplifies the construction of user interfaces (UI) for server-based applications by using reusable UI components in a page.
Message-oriented middleware (MOM) is software or hardware infrastructure supporting sending and receiving messages between distributed systems. MOM allows application modules to be distributed over heterogeneous platforms and reduces the complexity of developing applications that span multiple operating systems and network protocols. The middleware creates a distributed communications layer that insulates the application developer from the details of the various operating systems and network interfaces. APIs that extend across diverse platforms and networks are typically provided by MOM.
GNOME-DB is a database application by the GNOME community. The project aims to provide a free unified data access architecture to the GNOME project for all Unix platforms. GNOME-DB is useful for any application that accesses persistent data, since it now contains a data management API.
Push technology or server push is a style of Internet-based communication where the request for a given transaction is initiated by the publisher or central server. It is contrasted with pull, or get, where the request for the transmission of information is initiated by the receiver or client.
XML Interface for Network Services (XINS) is an open-source technology for definition and implementation of internet applications, which enforces a specification-oriented approach.
Bombus is a GPL instant messaging client for the XMPP protocol. It is written in Java, and runs on Java ME/MIDP capable cellphones, including Windows Mobile platform with installed Java ME virtual machine, or any other platform, where Java ME is available. There was successful compilations of Bombue for Android.
Echo is a web application framework created by the company NextApp. The latest iteration, Echo3, allows writing applications in either server-side Java or client-side JavaScript. Server-side applications do not require developer knowledge of HTML, HTTP, or JavaScript. Client-side JavaScript-based applications do not require a server, but can communicate with one via AJAX.
Jingle is an extension to XMPP which adds peer-to-peer (P2P) session control (signaling) for multimedia interactions such as in Voice over IP (VoIP) or videoconferencing communications. It was designed by Google and the XMPP Standards Foundation. The multimedia streams are delivered using the Real-time Transport Protocol (RTP). If needed, NAT traversal is assisted using Interactive Connectivity Establishment (ICE).
XPages is an IBM implementation of JavaServer Faces with a server side JavaScript runtime and the built-in NoSQL database IBM Domino. It allows data from IBM Notes and Relational Databases to be displayed to browser clients on all platforms.
Effi is C++ application development framework.
Socket.IO is an event-driven library for real-time web applications. It enables real-time, bi-directional communication between web clients and servers. It consists of two components: a client, and a server. Both components have a nearly identical API.
Apache Attic is a project of Apache Software Foundation to provide processes to make it clear when an Apache project has reached its end-of-life. The Attic project was created in November 2008. Also the retired projects can be retained.
Xabber is a XMPP client for the Android Operating System. It is developed as an open source Project on GitHub and is licensed under the GNU GPL v.3 license. The original developers are from a software company called Redsolution, Inc. Xabber is available on the Android Play Store and on F-Droid.
The JSON Meta Application Protocol (JMAP) is a set of related open Internet Standard protocols for handling email. JMAP is implemented using JSON APIs over HTTP and has been developed as an alternative to IMAP/SMTP and proprietary email APIs such as Gmail and Outlook. Additional protocols and data models being built on top of the core of JMAP for handling contacts and calendar synchronization are meant to be potential replacements for CardDAV and CalDAV, and other support is currently in the works.
