OSGi after working on the first project. Even Java is not how can, all of a sudden with OSGi, all kinds of concept nouns do not understand, and there is no time to study deeply, only in the framework has been set up to write transactions, write business processes, database additions and deletions to change, after a long time to understand slowly.This series of notes mainly introduces the

Modular Specification In Java, there is no modular concept, or there is no de facto standard. Is how to form a module, which modules are used internally, and which modules are used externally. Osgi can solve the above problems and ApplicationsProgramIt can be built like building blocks. For example, for a running system, the log service module is not provided in the system, then, you can directly develop the corresponding log service module and dy

We'll look at some typical problems with class loading in the order of increased complexity, and develop a small piece of code to solve the most interesting of these problems. Even if you're not going to write a code generation framework right away, this article will give you a more in-depth understanding of low-level operations in the runtime (such as OSGi systems) that statically define dependent modules. This article also includes a working demo p

In the previous articleArticleThe osgi series-one of the Web applications for developing servers: Servlet implementation, describes how to develop servlet methods under the osgi framework. However, not all web applications only have servlets and there are many static resources, such as HTML, images, CSS, and Js, in this article, we will continue to explain how to include these static Resources in the bundle

This article describes how to configure a simple Web Application Based on Eclipse equinox osgi in eclipse.ProgramYou can 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 use it. 1. Support for static pages and servlets 1. create a new plugin project, net. bjzhanghao. osgi. test, select "this plug-in is target" in the fir

In the previous article, introducing the relationship between structural modularity and agility, in the second article in this series, we'll discuss OSGi, which plays a central role in implementing Java's structural modularity, and there is a natural link between OSGi and popular agile methodologies. 1 but we have achieved modularity! The vast majority of developers agree that the program should be modula

Course Introduction OSGI technology is a Java-oriented dynamic model system. There is a very famous phrase in the Java circle: OSGI-architect's paradise. In other words, OSGI makes software development easier. Thankfully, there is a similar framework-CTK Plugin Framework in C + +. It draws on the idea of OSGi and impl

Solve the NoClassDefFoundError of third-party packages in the OSGI environment-Linux general technology-Linux programming and kernel information. The following is a detailed description. I finally fixed this problem and made a conclusion: 1. Transform the class file of a third-party package into a bundle and export all packages. 2. Use equinox of eclipse to start all bundle 3. In the eclipse environment, the startup is normal, but it fails to be st

These days have been learning and deepening some of OSGi's things, and went to see the next Apache Felix several example, so decided to write some of Felix example, but not in the Felix official website to run, Instead of learning from a new OSGi operating environment, the KARAF is used as a running container for OSGi while integrating camel in, since there will be more use of

OSGi Life Cycle ManagementThe OSGi life cycle layer has two different roles: Outside of the application, the related operations on the bundle lifecycle are defined. The

independent and simple as possible. A module with low vertical complexity is not required for any framework, and we can divide the layers of each module based on the vertical complexity of the module. However, we have to solve the problem of introducing modular system architecture: (1) how to assemble modules? (2) how to solve the module dependency? (3) how to ensure the independence of modules to reduce the mutual influence between modules? (4) How to develop, debug, and deploy modules? The pr

Today, in the course of learning OSGi, the first HelloWorld plug-in project was built as described in the book, and the following error occurred during the running process:!

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
