- 13. Core • Launching • Bundle Tracker • Bundle-License Header • Service Hooks • Negative Permissions vrijdag 26 juni 2009
- 14. Launching • To be inside a framework … • Or outside a framework ... • That’s the question! vrijdag 26 juni 2009
- 15. Launching • Standardizes launching different frameworks • Will enable generic launchers • Allows you to embed a framework in your application! vrijdag 26 juni 2009
- 16. Launching Map<String,String> p = new HashMap<String,String>(); List<String> impls = getMetaInfServices( loader, FrameworkFactory.class.getName()); if (impls.size() != 1) throw new RuntimeException( "Too many frameworks: "+ impls); Class<?> clazz = loader.loadClass(impls.get(0)); FrameworkFactory factory = (FrameworkFactory) clazz .newInstance(); Framework fw = factory.newFramework(p); Bundle b = fw.installBundle( “http://.../load/…”); b.start(); vrijdag 26 juni 2009
- 17. Bundle Tracker • Simple tool a la Service Tracker to track bundles • Very useful for extenders • Bundles that provide additional functionality based on data in a bundle • Tracks a set of states • Handles all concurrency issues vrijdag 26 juni 2009
