osgi-bundle

问题 I'm using the maven-bundle-plugin 3.3.0 and OSGI R6. I have the following classes: //Class A @Component (immediate = true, service = {}) public class A{ private static B myB; @Reference (unbind = "unbindB") public static void bindB(B pB) { myB = pB; } public static void unbindB() { myB= null; } } //B class. It does not implement any interface. Hence, the service must be itself @Component (immediate = true, service = B.class) public class B{ @Activate public void activate(){ //B activated } }

问题 I'm quite new to OSGI framework so I do not how to deploy multiple processes(bundles) in 1 jar onto it. Particularly, I have installed the Apache Felix With Web Console following this link. I have also tried to deploy my jar file and started it as the bundle. The jar's purpose is like a job to process some activities. However, I would like to have multiple jobs in just 1 jar file so that when I deploy that jar on Felix the framework can identifies and presents them as individual parts. For

问题 I want to write an OSGI Bundle (Eclipse SmartHome Binding) for the GPIO's of a Raspberry Pi. For the GPIO's i need to include the Pi4J libraries.

问题 I am trying to understand the intended use case for Bundle-Classpath in OSGI bundles. Here is my understanding, please help me understand if this is correct. Let's say I am working on creating an OSGI bundle which will be deployed in an ecosystem of other bundles. The bundle I am working on needs some other bundles, but they are not loaded/exported in this ecosystem, and I do not have control on what the ecosystem exports. In such a scenario, I can put these bundles inside some directory (say

问题 I want to deploy some jobs as instances in my jar (bundle) and when I deploy that jar onto Felix, maybe the Web Console can define the jar as 1 bundle but it could present these instances also. Moreover, I could do some bundle function on the instances like update/start/stop/... 来源： https://stackoverflow.com/questions/60808451/deploy-multiple-instance-in-1-bundle-osgi

问题 I have some little silly doubts in an OSGI concepts but they need to be clarified to have better understanding of concepts. Can anybody tell me what is the difference between OSGI Service and Component.

Please let me know if i am wrong or suggest some link from where i can get the things nicely. 回答1:

问题 I'm using maven-bundle-plugin ( bnd effectively). It's straightforward to include a resource file from sources. For example, a resource file ( src/main/resources/some.xml ) is moved under target directory ( target/classes/some.xml ) during build time and can be included into the bundle using <Include-Resource> instruction: <plugin> <groupId>org.apache.felix</groupId> <artifactId>maven-bundle-plugin</artifactId> <version>3.0.1</version> <extensions>true</extensions> <configuration>

问题 I have an OSGi compliant bundle(jar), in which I want to add a jar of a dependency. The dependecy I want to add is of a Database Driver. That jar is not present in the lib folder of the Karaf container which I am using, and there is no way of adding it there manually. I have access only to the deploy folder, where I can deploy my bundles. I am using maven bundle plugin to package my bundle. So, I wanted to know whether there is a way to add the dependency jar in my bundle. Currently, I am
