osgi specification solves all problems of modular applications for us. For (1), in osgi, each module is called a bundle, that is, a service package, which consists of a bundle list file, code file, and resource file. The osgi framework can load modules from a file, folder, or URL. Osgi fully defines the units of the m
This article describes how to configure a simple eclipse-based Web Application Based on Eclipse equinox osgi and how to construct more complex applications based on it. This article uses eclipse 3.3.1, if your eclipse version is 3.2.0 or later, you can. 51cto: Introduction to osgi and full introduction to practice 1.

Finally, the question of controlling the KF framework and letting
Eclipse 3.0 does not replace the original plug-in mechanism with osgi. It is only compatible with the standard: it provides users with a series of APIS for access. In this process, some changes must be made (such as plugin registry and loading mechanism) to be fully compatible with osgi standards. The original plug-in core only supports static expansion. That is to say, to change an existing plug, you must

Recently started to study OSGi, but began to see some online articles. Osgi+spring and so on and so on, I don't know what OSGi is used to do at any time. What role does he play in the Java EE architecture? Look for some information. The advantage of OSGi is the use of plug-in development to use the entire process of th

As a new de facto industrial standard, OSGi has received wide attention, its service-oriented (interface) basic idea and the capability of dynamic module deployment are the goals that enterprise applications have been pursuing for a long time. Spring is a well-known lightweight Java development framework characterized by interface-oriented programming and non-invasive dependency injection. The combination of OSGi
The spring-osgi default load resolves an XML file in the Meta-inf/spring directory as a spring bean configuration file, or you can specify a spring bean configuration file by adding Spring-context to MANIFEST.MF. To publish a spring bean as an OSGi Service, simply configure it in the XML of the Spring bean: To reference an OSGi Service in a spring bean, simply

Every successful man in eclipse, equinox, and osgi has a great woman. Every successful product has a strong architecture behind it-Question Many Java programmers have a crush on Eclipse (sun, which is the name of eclipse and IBM). In JBuilder's popularity and mainstream memory configurations, after I successfully run eclipse for the first time, I took JBuilder out of my computer's hard drive. Yes, this is the charm of Elipse.
