osgi in action

After writing the analysis of the service framework based on OSGi, the decision was made to implement a distributed service framework based on OSGi, and its feature would be implemented in accordance with the elements of the service framework previously written, based on the previous analysis, This implementation process is divided into three major steps to complete: spike phase, implementation phase and te

Use osgi to develop HTTP services. The default port is 80 at startup. However, this port may have been occupied by other programs on the local machine. There are two solutions to the problem: 1) closing or modifying the port that occupies the program; 2) modifying the port at osgi startup. It is also easy to modify the port number when osgi is started. You can a

The following is from Zhou Zhiming's in-depth understanding of Java virtual machines.Learn the JEE specification, go to the JBoss source code, learn the class loader, to see the OSGi source code.OSGI, the Open Service Gateway Initiative, is a dynamic modular specification based on the Java language.Only the export package can be accessed by an external module.OSGi allows for module-level hot-swappable functions.The relationship between the loaders in

Equinox is an osgi Implementation of eclipse, and later versions of eclipse3.1 are all started through it. You can download the latest equinox version from the eclipse website at http://download.eclipse.org/equinox /. If you have installed a version later than eclipse 3.1You can findOrg. Eclipse. osgi_3.2.0_xxx.jarThis is the implementation file of equinox. HereArticleWe useOrg. Eclipse. osgi_3.7.2.v20120110-1415.jarFor example. Create

The MVC framework, such as SPRINGMVC, is temporarily unsupported in OSGi, and when we write a method, we need to create a new servlet, which is cumbersome, so we want to implement an MVC framework that works in an OSGi environment, mimicking the SPRINGMVC or struts2 framework.1. First we look at the configuration of Web. Xml. It defines a servlet that filters all URIs with. Do, and initializes the parameter

Felix is an Apache-owned framework for implementing OSG specification I. Access Address: http://felix.apache.org/ Building the basic OSGi framework only requires downloading the Felix framework. Unzip to any directory (for example: D:\felix-framework-4.4.1), open cmd Command window in felix-framework-4.4.1 directory, execute launch Felix framework command Java-jar Bin/felix.jar Enter the LB command to view the current launch of Felix's bundle afte

It looks normal when you are working directly with the plugin that you are developing. But when the export was put into eclipse, there was something wrong with the plugin running. This time you need to debug the plugin in the console of OSGi, this article will tell you how to debug the Eclipse plug-in simply (the plugin has been exported).1. Send the eclipse.exe of the eclipse that was placed into the plugin to the desktop shortcutPS: I developed the

The first step is to build an OSGI environment;Open Eclipse, click run-"Run Configration:, configure as follows, click Run."The result of the operation is as follows: The OSGi environment is built.Step two: Build an OSGi-based Web development environmentTwo ways: The first, tick the required bundle, list asSecond, tick the box below and click Add Required bundles

Class loading in OSGiIn OSGi, there are multiple classloader, each of which loads a separate module, and when other modules need to find the class, the OSGi framework relies on the relational table to find the loader that the class is in, and the loader is commissioned to runClass loading in OFBizOFBiz integrates many applications, such as order, security, login, online, and Tomcat are also integrated into

In the traditional way, we can register the service through Bundlecontext.registerservice () in the bundle's activator (called when the bundle starts), through SERVICEREFERENCESR = Bundlecontext.getservicereference () and Bundlecontext.getservice (SR) are serviced in two steps. But there are many drawbacks to this approach: 1. Generate more Duplicate code 2, at startup to instantiate all the services to be published, affecting the startup time 3, some registered services will not be used during

This article describes how to configure a simple Web application based on Eclipse Equinox OSGi in Eclipse to build a more complex application based on the Eclipse version 3.3.1, which is used in this article. If your eclipse version is 3.2.0 or above, it should be OK. One, support static pages and servlet 1.
