Why can't JAXB find my jaxb.index when running inside Apache Felix?

由 本秂侑毒 提交于 2019-11-28 16:25:44
问题 It's right there, in the package that it should be indexing. Still, when I call JAXBContext jc = JAXBContext.newInstance("my.package.name"); I get a JAXBException saying that "my.package.name" doesnt contain ObjectFactory.class or jaxb.index although it does contain both. What does work, but isn't quite what I want, is JAXBContext jc = JAXBContext.newInstance(my.package.name.SomeClass.class); This question from various other people appears on quite some mailing lists and forums but seemingly

What is the difference between OSGi Components and Services

由 一世执手 提交于 2019-11-28 15:58:46
问题 Under OSGi, what are the main differences between Components vs Services? As I understand it, all Services must be Components, but not all Components must be services. What are the benefits of using one over the other with sample use cases? 回答1: "Components" are less formally defined than services. A service is any object that is registered in the OSGi Service Registry and can be looked up using its interface name(s). The only prerequisite is that a service should implement some interface...

What's the best way to get started with OSGI? [closed]

由 亡梦爱人 提交于 2019-11-28 15:30:58
问题 What makes a module/service/bit of application functionality a particularly good candidate for an OSGi module? I'm interested in using OSGi in my applications. We're a Java shop and we use Spring pretty extensively, so I'm leaning toward using Spring Dynamic Modules for OSGi(tm) Service Platforms. I'm looking for a good way to incorporate a little bit of OSGi into an application as a trial. Has anyone here used this or a similar OSGi technology? Are there any pitfalls? @Nicolas - Thanks, I've

How to modularize a JSF/Facelets/Spring application with OSGi?

由 我是研究僧i 提交于 2019-11-28 15:22:31
问题 I'm working with very large JSF/Facelets applications which use Spring for DI/bean management. My applications have modular structure and I'm currently looking for approaches to standardize the modularization. My goal is to compose a web application from a number of modules (possibly depending on each other). Each module may contain the following: Classes; Static resources (images, CSS, scripts); Facelet templates; Managed beans - Spring application contexts, with request, session and

Google Client API in OSGI

由 非 Y 不嫁゛ 提交于 2019-11-28 14:18:09
I'm having trouble providing the dependencies needed for OAuth Client Library for Java within an OSGI application framework (AEM). https://developers.google.com/api-client-library/java/google-oauth-java-client/setup I don't want to manually convert each dependency to an OSGI bundle, BND. So I'm using maven-bundle-plugin to embed these into my bundle. My process so far has been to watch the error.log for messages about 'Unresolved constraint in bundle.' Then track down the missing package, add the maven dependency, and add it to the Embed-Dependency section. That seemed to work for google-http

Apache Maven Assembly Plugin not working with OSGi bundles

由 試著忘記壹切 提交于 2019-11-28 11:48:59
I have a Maven OSGi multi-module project. The project runs perfectly well when the OSGi picks the module jars from the individual project modules. (view 1.1.B below) . However, using a second approach, bundle.getRegisteredServices() (view 1.1.A below) returns null whenever I try using bundles deposited into a central folder (D:/parent/provider/target/modules) using the maven-assembly-plugin version : 2.6 : framework.getBundleContext().installBundle("file:D:/parent/provider/target/modules/OSGiDmHelloWorldProvider-1.0.jar"); framework.getBundleContext().installBundle("file:D:/parent/provider
