Getting Started with Osgi--apache Felix

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

Introduction to OSGI Specification

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

Using Eclipse to develop bundle applications based on OSGi

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
