Introduction
This article is part 1th of this series, and we will develop an order application that contains both client and server-side components. These components are then packaged as OSGi packages. The client invokes the service component to process the order. The service component has methods for processing orders and printing order IDs. After reading this article, you can apply the concepts and features of Apache Felix to build and package Java
OSGI (Dynamic model system for Java)The OSGi (Open Service Gateway Initiative) technology is a series of specifications for the dynamic modular system of Java. OSGi refers to OSGi, on the one hand, that maintains OSGi specificationsThe official alliance, on the other hand, r
Starting with V3.0, Eclipse has made a huge leap by choosing the Open Service Gateway Protocol, open Services gateways Initiative,osgi, to replace the unstable Eclipse plug-in technology in previous releases. This transition is almost transparent to the user, because the plugin you are using now installs and operates in a manner that does not look any different from the previous plugin.

The relationship between Eclipse and OSGi, from Plugin.xml to MANIFEST.MF
The core of the Eclipse Integrated Development Environment (IDE) and Eclipse Rich Client Platform (RCP) applications is driven by the implementation of the Open Services Gateway Initiative (OSGI) specification. This article illustrates the relationship between Eclipse and OSGi by describin
Osgi: the foundation of eclipse
Osgi provides a set of standard component-oriented specifications for network services. network services are the basis of Service Oriented Architecture. by using the osgi platform, you can easily manage the lifecycle of software components. These components can be deployed on any device on the network, and can be dynamically instal

Osgi, as a new de facto industrial standard, is booming in various fields, while web development technology has long been widely used as a mainstream technology in the software industry. How traditional Web developers combine web development and

The original purpose of OSGi (Open Service Gateway Initiative) is to provide a common software running platform for a variety of embedded devices, that is, a middleware platform that can shield the difference between device operating systems and hardware. PCs are basically monopolized by the Wintel architecture, and applications running on PCs can be run on another PC, but different for other devices, their hardware platforms may be completely differe
The Open Service Gateway Protocol (Open Services Gateways Initiative), referred to as OSGi, defines a standard, service-oriented computing environment for network services, and provides users with an open, service-oriented component, easily deployable programming model, This programming model allows users to bind well-defined interface specifications to specific services in an OSGI runtime environment, and
1. BackgroundWith the recent modularity of Web projects to support hot-swappable, dynamic scaling, we began to look at how OSGi can be introduced into Web projects. For OSGi, you can refer to OSGi research and summary. Now that the mainstream Java EE framework is inseparable from spring, the seamless integration of OSGi
OSGi is the abbreviation for the Open Service Gateway initiative, which was established in 1999 and is a non-profit organization designed to establish an open service specification to open standards for service delivery over the network.
The OSGi specification includes various aspects of building an open, deliverable Network Service, and the OSGi specification i
A recent study, which learned about OSGi Technology, felt that OSGi was somewhat difficult to learn. But finally mastered and popularized will be a more practical technology for system development. Here and everyone to share their own sentiment. 1. What is OSGIOSGi , an "open service Gateway", is a Dynamic modular specification initiated by the OSGi Consortium wi
HelloWorldIn general, learning a new technology, programmers are accustomed to first develop a Hello World application, which seems to be an "industry standard." OK, let's get started, it's not difficult to develop a simple OSGi application, as follows: Build a plug-in project, File > New > Project, select Plug-in development > Plug-in PROJEC TFigure 1. New Plug-in ProjectIn the first wizard to build the project, fill in the name of the project: Osgi.
Brief introduction
OSGi modularity provides a standard mechanism for meeting common challenges with Java applications. In 2007, the OSGi Alliance Enterprise Expert Group (EEG) was established to introduce the OSGI infrastructure to business application developers in the form of a business Java programming model. The OSGi
Study OSGi also for some time, the total feeling of online related information is too little (reference value, because most are copies of the same article), so far to OSGi is a certain understanding, I took this time to find the information and personal experience summed up and share, for the open source to do a little humble power .

The first and most important point is that osgi-based applications can dynamically change the running status and behavior. I have participated in the development of J2EE enterprise-level projects. The application server uses IBM WebSphere and mainly develops some appli
