问题 How can I add packages to a bundle's import from within code? I need it since I use libraries which rely on reflection and require other packages and I don't want to need to manually add those packages to MANIFEST.MF for each bundle I develop 回答1: You cannot. Import-Packages are evaluated in the Resolution phase. (Phases are Installed -> Resolved -> Active ). Your code is executed when the bundle is Active, therefore too late to add Import-Packages. You can do 2 things: Import-Package the

问题 I am trying to use the Spring AOP for logging purposes. I have set up the logging bundle, and the OSGi service in it. I have other OSGi bundle which uses the service from logging bundle as a OSGi reference. The logging bundle is deployed into Apache Karaf and running. I can not get my other bundle deployed. The spring configuration in my bundle is like that: <osgi:reference id="loggingIterceptor" interface="com.groupgti.commons.log.LoggingInterceptorAdvice"/> <aop:config> <aop:pointcut id=

问题 I've successfully started Hibernate in an OSGi context, and now I want to add Envers. The documentation claims that's possible. I don't believe it anymore. There is no documentation of any kind for this subject and nobody seems to have actually done it. Moreover even with a Blueprint implementation I had to hack the classloader to make Hibernate even find Envers: osgiClassLoader = new org.hibernate.osgi.OsgiClassLoader(); osgiClassLoader.addBundle(requestingBundle); osgiClassLoader.addBundle

问题 I'm trying to code a OSGI REST bundle with bndtools. I added all the jars that I need in the cnf project. Then I added them to the bundle build path. I get the following runtime exception OSGi bundle not started : missing requirement osgi.wiring.package (&(osgi.wiring.package=javax.ws.rs)(version =2.0.0)( (version =3.0.0))) I don't understand the error because I use javax.ws.rs-api 2.0.1. I tried to specify the version explicitly in the buildpath like this -buildpath: \ javax.ws.rs-api

问题 For a project I'm trying to get Excel XML functionality using Apache POI to work with OSGI. I've tried the POI ServiceMix bundle, but this was missing the ooxml-schemas jar. Adding the jar to the bundle and including it in the manifest didn't seem to work. Then I tried to creating wrapper bundles for POI 3.10, but also to no avail. Same error. Caused by: java.lang.ClassNotFoundException: org.apache.xmlbeans.impl.schema.SchemaTypeSystemImpl not found by org.apache.poi [8] at org.apache.felix

问题 I'm pretty new to the OSGI, Felix and Maven stuffs, just started with it. I'm deploying the java build through jenkins and I get the below dependency issue. Below is the pom file contents which includes the dependency, I'm not sure whether it is correct, but it still complains about it. It is looking for "javax.jws" and the version is between 2.0 and 3.0 javax.jws;version>="2.0.0",!javax.jws;version>="3.0.0" Below is the pom contents. <Import-Package>!sun.misc,!org.apache.avalon.framework

问题 I have and osgi based application. The loading process is the following: start.sh runs not osgi loader.jar which starts felix and installs and starts bundles. By other words start.sh->loader.jar->osgi+bundles. I want to show loading process in loader.jar via javafx and I use there Application.launch(Gui.class). Everything is ok. The problem appears when in osgi bundle main program is started (also via Application.launch) and I get : Caused by: java.lang.IllegalStateException: Application

问题 I have my datasource configured in tomcat\context.xml. I have deployed a bridge.war provided by Eclipse to get servletbridge environment. I have developed another osgi bundle which contains servlet registation code and my aim is to do JNDI look up for datasource from this servlet bundle. However I get javax.naming.NoInitialContextException:Cannot instantiate class: org.apache.naming.java.javaURLContextFactory (root cause classnotfound for org.apache.naming.java.javaURLContextFactory) when I

问题 I am trying to convert my project into an OSGI application. I have few doubts. Suppose ModuleA in my application is dependent on external jars jarA and jarB. Now to make ModeuleA run, I am embedding both the jars using embed-dependency property of maven-bundle-plugin. Now suppose I have another module ModuleB which is also dependent on jarA. So this module also embeds the jarA. My project ends up having jarA being embedded 2 times which will unnecessarily bloat the size of project. Is there
