OSGi Introductory article: module layer1 What is modularityThe module layer is the most basic part of the OSGi framework, where the modular nature of Java has been well implemented in this layer. However, this implementation is obviously different from some of the existing modularity features of Java itself. This article describes some of the basics of the module layer and some of the considerations that
Bluedavy, a new employee from brothers, was just an indirect mentor when I started osgi (I read his osgi Advanced Course and shared some practical experiences). I met bluedavy for the first time on the Internet at noon, after talking about it for a while, I have a little time in the afternoon to read three new articles about osgi, SCA, and service framework. I ha
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
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

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
Introduction to OSGi: Life cycle LayerObjectiveThe life cycle layer in the OSGi framework belongs to the layer above the module layer, and its operation is based on the function of the module layer. One of the main functions of the life cycle layer is to enable you to manage applications externally or to build self-managed applications (or the combination of the two), and give the application itself a great
Osgi-open Service Gateway initiative is a public service platform.
Several features of osgi:
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
For details about headers see section 3.2 of the OSGi specification. Some of the OSGi implementation frameworks may support some unusual jar packages, but the format of the jar packages about OSGi is unchanged.
The Spring Extender recognizes a bundle as "spring-powered" and'll create a associated application context when the bun Dle is started if one or both of
A few days ago, I used spring DM to create a simple web application. I had already written all the jar packages and ensured that the environment was in normal use,
However, after sending a request to the front-end of the page, the backend always reports that the corresponding class cannot be found. Of course, this exception is not just a simple introduction but a startup level problem,
However, since osgi was first introduced, all the startup levels i

Whether interface-oriented development can be implemented is closely related to the container or framework used by the system. The most important thing for interface-oriented development is to solve the system dependency problem, at this point, the most mature solution is IOC, and the most successful IOC container is spring. Does osgi-based solution bring different perspectives, let's take a look at these examples:1. Class A: Class A that implements t
Osgi startlevel explained and using startup level mechanism and usage
Bundle startlevel
In the actual application environment, our bundle is dependent on each other, so there must be a difference in the startup sequence, such as building a building,Start from laying the foundation.In fact, the initial start level of the osgi framework is 0,The startup sequence is as follows: add one to the startup level
Consider a scenario where you need to use a non-osgi jar in your OSGi project. Most libraries is not OSGi bundles and we should repackage all them with OGSi headers to being loaded into the OSGi containe R. There is several ways to help you with these Non-osgi dependencies:
There are two typical osgi application cases: Eclipse and BMW application control systems.
Eclipse
As a successful ide project in the Java industry, eclipse used its own plug-in Architecture in versions earlier than 3.0. Eclipse's plug-in architecture is well-known throughout the industry, it is also considered a very successful design, but eclipse made a major decision in version 3.0, it is to overturn its previous plug-in Architecture (although it i
ModuleIn osgi, the module is implemented in bundle. A bundle is a jar file, which contains the required class files and resource files. It must also contain a description file; each bundle can be independently packaged and deployed. Do you think it is similar to the war definition in J2EE?In terms of form, they are indeed very similar, and their main differences are:1) The war file of J2EE has a large granularity, in the unit of application; while the
