java - org.osgi.framework.BundleException: Unresolved constraint in bundle SampleModel -

i trying launch osgi framework programatically. using felix framework this. below code have launch osgi container.

public goldeneyeapp() {      try {          frameworkfactory frameworkfactory = serviceloader.load(frameworkfactory.class).iterator().next();         map<string, string> config = new hashmap<string, string>();          //todo: add config properties         framework framework = frameworkfactory.newframework(config);         framework.start();          bundlecontext bundlecontext = framework.getbundlecontext();          modulesnameversionholder.put("samplemodel", "1.0.0");          list<bundle> installedbundles = new linkedlist<bundle>();          string basepath = "c:\\clienttool\\localstorage";          (map.entry<string, string> entry : modulesnameversionholder.entryset()) {              string version = entry.getvalue();             final string filename = name + constants.dash + version + constants.dotjar;             final string localfilename = constants.file_protocol + basepath+ file.separatorchar + filename;              installedbundles.add(bundlecontext.installbundle(localfilename));         }             (bundle bundle : installedbundles) {             bundle.start(); // line throws exception start samplemodel bundle         }     } catch (bundleexception e) {         e.printstacktrace();     } } 

in above code, trying install , start simple osgi module (samplemodel jar) have created. try start module, below exception-

org.osgi.framework.bundleexception: unresolved constraint in bundle samplemodel [6]: unable resolve 6.0: missing requirement [6.0] osgi.wiring.package; (&(osgi.wiring.package=net.sf.cglib.core)(version>=2.1.3)(!(version>=3.0.0)))     @ org.apache.felix.framework.felix.resolvebundlerevision(felix.java:3974)     @ org.apache.felix.framework.felix.startbundle(felix.java:2037)     @ org.apache.felix.framework.bundleimpl.start(bundleimpl.java:955)     @ org.apache.felix.framework.bundleimpl.start(bundleimpl.java:942)     @ com.host.stream.goldeneye.goldeneyeapp.<init>(goldeneyeapp.java:62)     @ java.lang.j9vminternals.newinstanceimpl(native method)     @ java.lang.class.newinstance(class.java:1345)     @ com.host.jetstream.application.jetstreamapplication.getinstance(jetstreamapplication.java:71)     @ com.host.jetstream.application.jetstreamapplication.main(jetstreamapplication.java:94)

you using 'import-package: net.sf...' in manifest haven't installed cglib(or spring framework) osgi runtime yet. if import-package doesn't resolve every required package, bundle won't start.

edit: forgot had this: https://gist.github.com/sheenobu/5935468 . if pax-url working, can start installing arbitrary urls.

edit2: clear frameworks cache otherwise end installing packages multiple times. or check if package installed bundle and, if so, don't install it.
