osgi

问题 I'm creating OSGi dynamic bundle which should communicate with database and I am using Hibernate as I used it in non OSGI application. I putted original hibernate jars in the OSGi project's lib dir, and make sure those jars are on the project's build path and runtime class-path, I copied all configuration files(i. e. hibernate-cfg.xml) in the root of the OSGi bundled jar. When I execute my bundle (JAR) inside OSGi container it throws error for not finding hibernate-cfg.xml file. Maybe

问题 Please help me on my concern wherein I tried to Install/Upload the recruitment-client-1.0.0.jar in AEM Web Console Bundles of AEM 6.0 and the status is just "Installed" that should be "Active" , so when I tried to click play under Actions column, status is still "Installed" and has an error in log file seen below. *FYI that it works before in CQ5 server instance. org.apache.felix.http.jetty %bundles.pluginTitle: Cannot start (org.osgi.framework.BundleException: Uses constraint violation.

问题 What's the best way to create a simple osgi (deploying into virgo server ) project using maven , to create a war structure with pom.xml maven descriptor? A Structure target is *.jsp *.html META-INF MANIFEST (OSGI-CONFIG) WEB-INF classes lib web.xml Then when I create a project This is my pom.xml project properties <groupId>com.aaaa</groupId> <artifactId>first-maven-virgo-project</artifactId> <version>1.0.0</version> <packaging>war</packaging> Felix Plugin <plugin> <groupId>org.apache.felix<

问题 once again it has happened... I joined a new project, composed of several plain Eclipse Java Projects, with interdependencies, all managed through the Project build path. I find this all a bit of a chaos. And when it comes to run configurations - you just enter hell. In the past I've sticked to create plug-in projects, instead of plain Java projects - even if I never intend to run these projects as osgi-bundles. I just find that dependencies are way easier to manage in plug-in projects. Are

问题 I am using this simple pom.xml to generate an OSGi-bundle using the maven-bundle-plugin : <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>de.test.osgi</groupId> <artifactId>test</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>bundle</packaging> <build> <plugins> <plugin> <groupId>org

问题 I am learning OSGI, CQ5 these days. I am trying to build a bundle that have service (My first code). I successfully build a bundle and upload that bundle on CQ5, and install that also. But component shows registered only, not active . Why ? I also want to activate this service. How can I do this ? Someone on net said to make jsp. I also do that, but didn't get any response. Help me from this problem. I spent lot of time on this, lot of searching, but I didn't get any solution. How can I use

问题 I'm getting the beloved error: java.sql.SQLException: No suitable driver found for jdbc:postgresql://localhost:5432/acme I understand many reasons why this error usually arises: Invalid URL: This URL doesn't seem to have any errors in it and works perfectly fine in SQL Workbench. Driver Not on ClassPath: It is successfully imported (org.postgresql.Driver) and can be instantiated either directly or by using Class.forName("org.postgresql.Driver"). The Hibernate SessionFactory loading is

问题 I start felix framework myself. Everything is ok. But when I started with declarative services I see that felix ignores OSGI-INF/temp.xml. In manifest I added via maven Service-Component: OSGI-INF/temp.xml Even when I write wrong classes and interfaces in temp.xml I get no errors. Where is mistake or maybe I must enable something? 回答1: An OSGi framework does not process Service-Component header. That is processed by a Declarative Services implementation like Apache Felix SCR. Do you have that

问题 This question already has answers here : Access restriction: The type 'Application' is not API (restriction on required library rt.jar) (18 answers) Closed 4 years ago . I have an Eclipse RCP that interacts with java script. Now with Java 8, nashorn is used and code that depended on org.mozilla.javascript (plug-in org.mozilla.javascript_1.7.2.v201005080400.jar) must be changed to use jdk.nashorn.api.scripting. But when i try to use this import in Eclipse, it does not see it import jdk.nashorn

问题 OpenJPA, obviously. I've also seen EclipseLink and Hibernate mentioned, but is there significant difference in capabilities? 回答1: Most differences come from how OSGi-aware the provider is. For example, you may need to wrap the Hibernate jars as OSGi bundles yourself (or use a set someone else has already wrapped - there are a few floating around on the web). Occasionally providers try and do classloading in such a way that it won't work in an OSGi environment, so this is something to look out
