2.5 use metadata to define bundle
Metadata related to modules mainly includes the following three types:
· Human-readable information-this information is optional and is intended only for bundle users.
· Bundle identification-this information is used to uniquely identify a bundle.
· Code visibility-this information is used to define which codes are internally visible and which internal codes are externally visible.

Chapter 1 osgi
This book first points out that Java does not explicitly provide support for building modular systems, but only common Object-oriented Data encapsulation. Therefore, developers often need to make up for this. To make up for this and let application developers focus on application development, the osgi Service Platform came into being.
deep understanding of the relationship between GlassFish, HK2, and OSGi, while at the same time elaborating one's own point of view on the issues often referred to by the community. (Will HK2 be dead in the future?) ”)
PART8: Deep understanding of the GlassFish kernel (module configuration, loading, and startup), as well as showing how to extend GlassFish to add more custom modules in one case.
Part9: The process of contributing GlassFish
After the osgi container and osgi interaction are realized, a requirement is usually generated at the same time, that is, the plug-in the osgi container needs to load classes outside the osgi container, for example, an MVC framework is provided in the osgi container,
provided within the OSGi containers, and the action class is loaded by other containers outside the OSGi container. So this is the time to have this demand, and in order to do this, there is a relatively simple solution, is to write a bundle, in the bundle to allow the setting of an external classloader OSGi services,
The red content comes from personal understanding, and the rest comes from eclipse helps.
The comma-separated list of bundles which are automatically installed and optionally started once the system is up and running. Each entry is of the form:
If the start-level (> 0 integer) is omitted then the framework will use the default start level for the bundle. if the "Start" tag is added t
What is spring-DM?
Spring-DM refers to spring dynamic modules.

4.2 deploy bundle to the osgi environment using running parameters
4.3 deploy bundle to the osgi environment as a configuration file

As mentioned above, equinox includes the core framework, standard service implementation, J2EE-oriented applications, new deployment
Currently, there are few learning resources or technical documents about OSGI technology in the industry. I searched for "OSGI" books in a certain treasure net, but the results were there, but the kind was poor and few people bought it.
I need to learn OSGi for the reason of my work, so I have to try my best to learn OSGi

At this point you can also try to remove those two files from the E:workspaceosgidemoplugins Dbvalidatorbundle_18.104.22.168003301134.jar and Ldapvalidatorbundle_ 22.214.171.124003301134.jar, the system will be prompted to use cannot delete. At this point, the uninstall command Osgi>uninstall 1 2 To delete the two texts is successful, indicating that the JVM really unloaded the two packets. It can be seen how convenient it is for
Brief introduction to OSGi First we need to get to know what is Osgi,osgi also known as the Java Dynamic module, its biggest function is to help us implement Java modular application. OSGi is first a set of specifications, then a container, so we can easily compare it to Java EE technology, we know that Java EE ar

In essence, oop application systems are composed of types. In. net, classes are provided by the Assembly, and an application system is composed of a bunch of assembly, some of which are. NET framework is provided, some are provided by third parties, and the rest is custom assembly. An application system built based on the osgi. Net plug-in framework is composed of plug-ins.

Spring, the popular full-stack Java/Jee application framework in recent years. With the release of 2.0, spring is more comprehensive and powerful. osgi is not so famous, but everyone in eclipse is familiar with it. After eclipse 3.0, osgi is used as the basis for its plug-in architecture implementation.
To talk about osgi, os
Now more and more Java developers are talking about OSGi in a way that makes sense. When I went to school a few years ago, I did a lot of Eclipse plug-in development, and then I personally felt that the Eclipse plug-in system is flexible and powerful, and the system and OSGi are also feather. Recently intend to re-examine the system of OSGi, while learning to wri
1, the introduction of OSGi:OSGi is an abbreviation for Open Service Gateway initiative, a dynamic model system for Java. The OSGi service platform provides services to Java, which makes Java a preferred environment for software integration and software development, and is described in more detail on the encyclopedia:Http://baike.baidu.com/link?url=jZjzRuQzq7R_3i5Itkykb80ecbAC_ Ygfx-zpsrcu43zmsa13bmzgc86fydvxqe3csoeplphub2aicvx-cgnonpkkpqe9jctveqecocz
Publishing and using Services
Since the OSGi framework can easily hide implementation classes, it is natural to provide interfaces externally, and the OSGi Framework provides registration and query capabilities for services. OK, so let's actually do it on the basis of Hello World project. (If not please refer to previous article: OSGi notes (i) HelloWorld)
