osgi in action

Recently changed jobs, a lot of new things to learn, work more, blog has not been updated, sin ah. In recent days to see the knowledge of OSGi, while learning to remember it, to record their own way. Talk less, start. The concept of OSGi I will not say, Baidu Google a bunch of random look at the, anyway, I am not a lecturer, more learning will understand. Today, just start by remembering a helloworld,yes,yo

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 simple example of developing OSGi based on Eclipse A. Overview OSGI SERVICE PLATFORM is a Java-based, open and unified Interface Standard Architecture Framework, The deployment of all modules in OSGi must be deployed in a bundle manner. Based on this framework, service providers, program developers, software providers, service management operators, and de

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

The newly added framework launch in OSGi R4.2 public draft This is the biggest improvement in the lifecycle layer, in the previous specification is simply described under the framework of the start and close, after the enactment of this specification, either start Equinox or Felix, can be started in the same way, in detail, this digest from the " Principles and best practices of OSGi. Let's take a look at

What is OSGi? OSGi is a Java modular specification, translated by the Open Service Gateway Protocol (open Services gateways Initiative) OSGi is not an application-level framework, but a specification at the software design levelWhat does it bring to us?1 reusable component accumulation and reuse, functional decoupling. (multiplexing, cohesion, and coupling can al

Eclipse's plug-in architecture allows us to flexibly define plug-ins and assemble them into pluggable software systems. osgi's declarative services (DS) there is a similar idea with eclipse extension points (see a detailed comparison Article). Naturally, if DS is applied to Web applicationsProgramWe will be able to build SOA Web applications by defining our own "extension points. "Configurable" in the question refers to the product/solution tailored to the customer by providing different package

About two years ago I received an email from bluedavy asking me if I could authorize him to translate the BND manual into Chinese. He explained that many people in China are using BND, however, there is a lack of relevant documentation. I am very happy to provide him with a webpage for publishing the Chinese version. The translated content looks strange. There are a lot of unfamiliar Chinese characters mixed with several familiar English words. It seems like you have met your friends in a distan

Http://oscar.objectweb.org/ What is Oscar? Oscar is an open source implementation of the open services Gateway Initiative (osgi) Framework Specification; the goal is to provide a completely compliant implementation of the osgi framework specification. oscar is currently compliant with a large portion of the osgi 3 specifications, although certain compliance work

OSGi actual finished, feel the author writes very well, then see the OSGi advanced this article OpenDoc, first of all, to build the environment, in the OSGi real environment, I set out according to the author's method of the problem, through a series of online search found a solution, If you are in the OSGi combat envi

Use the Open Services Gateway initiative API to eliminate Eclipse plug-in dependencies This article describes a plug-in example that uses XML to register extensions for well-defined extension points. By enabling Plug-ins to perceive extention Registry and provide OSGi services, we can complete this complete component decoupling operation. Plug-ins, extension points, OSGi As you know, Eclipse's component

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

First, what is OSGiThe OSGi (Open Service Gateway Initiative) technology is a series of specifications for the dynamic modular system of Java. OSGi, on the one hand, refers to the official OSGi alliance that maintains the OSGi specification and, on the other hand, the Java-language-based Service (business) specificatio

OSGI (Open Service Gateway Initiative) OSGI defines a dynamic model system that helps you better manage your code structure and code lifecycle, cooperation with code modules (loose ). Modularity-the code is divided into clear functional blocks with clear interface interactions between functional blocks. You will naturally think that Object-oriented has the concept of a module. But there are limitations: 1.
