问题 I am attempting to make karaf 3.0.4 use logback. In the code i attempt to programatically create a FileAppender for a logback logger. ch.qos.logback.classic.Logger logger = (ch.qos.logback.classic.Logger) LoggerFactory.getLogger("bingo"); Here the LoggerFactor is SLF4J LoggerFactory. I have not posted the code which adds the file appender. This throws the following exception in karaf: Caused by: java.lang.ClassCastException: org.ops4j.pax.logging.slf4j.Slf4jLogger cannot be cast to ch.qos

问题 I have a set of bundles deployed in Karaf and exposing a number of OSGi services which I would like to be able to lookup and call remotely, from an application running on a (possibly) different machine and in a non-OSGi container. My initial though was to use JNDI lookup to get the services I want however I understand from an earlier stackoverflow post that this might not be supported (I say might since I haven't been able to find any information on whether anything has changed on the Aries

问题 I am trying to add new custom log4j2 appender. Karaf 3.0.2 use pax-logging 1.7.4 which does not support log4j2. I have a appender which extend org.apache.logging.log4j.core.appender.AbstractAppender . I followed this blog http://blog.nanthrax.net/2012/12/create-custom-log4j-appender-for-karaf-and-pax-logging/ writen by Jean-Baptiste. It will not work because my appender is written in log4j2. What are the alternatives so that karaf also log using this appender? 回答1: The answer is already in

问题 I am trying to follow this tutorial: apache felix tutorial #1 But I don't understand the directory structure. Where do I place the Activator.java file? Where, relative to the Activator.java file do I place the MANIFEST.MF? In this tutorial when I try to compile the Activator.java file, I get errors that org.osgi.framework does not exist. Where can I get the org.osgi.framework package and where should it be installed? How does the javac build command know how to find the org.osgi.framework

问题 I have a problem on 2.2.8 version of Karaf (and most probably on the earlier versions too). I'm going to use Karaf to host the system with dynamically deployed bundles. Bundles are deployed by users and i cannot know beforehand which are they. I expect order of the BundleActivator.start() to exactly correspond to package dependencies between bundles (dependencies of import/export packages) and planning to expect that it will be safe to assume that bundle0 will be completely initialized before

问题 This is a problem that I am facing with Jboss fuse, where a dependency (Oracle JDBC JAR) is not found as an OSGI bundle. The source code works fine when run locally, but errors out when deployed on a Karaf container. A detailed explanation of the issue and associated source code is placed at: https://developer.jboss.org/message/948643 Any suggestions on this would be welcome. Thanks for your patience. Prabal 回答1: The Oracle JAR File that you are trying to deploying on the Fuse Server is not a

问题 If I want to execute a karaf shell command in my plugin (java), how to do it? ex: opendaylight-user@root> snmp4sdn:printdb "org.apache.felix.service.command.CommandProcessor" can handle it ? 回答1: In Karaf 3, you have to use the Felix Gogo services, ie the CommandProcessor . From a CommandProcessor , you can create a CommandSession and then call execute on this session. Two notes on this: In Karaf4, the service has changed - it's not dependent on Gogo anymore All the shell commands use an
