I wouldn't bother with previous releases. Or should we? As we're already using CL and Deployers snapshots, I guess we could fix Dependency and Kernel as well, still on the 2.0.x branch, to fit our needs. In the worst case making new 2.1.x branch, same as we did for VFS and Man, which could still be part of JBoss 5.x (aka "existing" jboss releases), leaving bigger MC 2.2.x refactorings for 6.x.

[JBoss OSGi Development] - Service integration with MC

by alesj

and vice versa. * Service --> MC "adrian(a)jboss.org" wrote : | The service layer is not so well integrated with the MC. It does just enough to | be "OSGi compliant" (of course that's not yet tested). So this is at the | moment very simple. | The OSGiServiceState which should eventually turn into an MC context implementation | has two "facades", the standard ServiceRegistration and ServiceReference interfaces. | * MC --> Service "adrian(a)jboss.org" wrote : | Services are also largely complete.

[JBoss OSGi Development] - @Override and JDK5 usage

by alesj

I'm getting compile errors since we're using @Override on interface impl methods. Afaik this is JDK6 feature, whereas we still wanna be JDK5 compatible. And Pete tells me this is auto feature of Eclipse if you're running JDK6. So, either use IDEA or turn this off. :-) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4252131#4252131 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4252131

[JBoss OSGi Development] - Invalid delivery of framework events

by thomas.diesler＠jboss.com

https://jira.jboss.org/jira/browse/JBOSGI-140 Although a listener is associated with a bundle context (i.e. must get removed when the bundle gets uninstalled) the events must get delivered to the listeners that are associated with the framework. sysContext.addBundleListener(listenerA); Bundle bndA = sysContext.install("bundleA.jar"); bndA.getBundleContext()..addBundleListener(listenerB); Bundle bndB = sysContext.install("bundleB.jar"); bndB.uninstall(); Both listenerA and listenerB must see the BundleEvents for bundleB. This delivery pattern is the basis of the much used "Extender Pattern" View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4252048#4252048 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4252048

[JBoss OSGi Development] - OSGi classloader system

by thomas.diesler＠jboss.com

Folks, I'd like to better understand how the classloader system works. Could you please talk me through the code below and explain what is being done here. Eventually, I'd like to be able to setup a Framework Classloader with the configured packages in 'org.osgi.framework.system.packages' and 'org.osgi.framework.system.packages.extra' | /** | * Create a new OSGiClassLoaderSystem. | * @param bundleManager the bundleManager | * @throws IllegalArgumentException for a null bundle manager | */ | public OSGiClassLoaderSystem(OSGiBundleManager bundleManager) | { | if (bundleManager == null) | throw new IllegalArgumentException("Null bundle manager"); | | ClassLoaderDomain domain = getDefaultDomain(); | | // Initialize the configured system packages | String sysPackageString = getSystemPackagesAsString(bundleManager); | PatternClassFilter filter = PackageClassFilter.createPackageClassFilterFromString(sysPackageString); | filter.setIncludeJava(true); | | domain.setParentPolicy(new ParentPolicy(filter, ClassFilter.NOTHING)); | AbstractJDKChecker.getExcluded().add(AbstractBundleState.class); | AbstractJDKChecker.getExcluded().add(OSGiBundleState.class); | } | | @Override | protected ClassLoaderDomain createDomain(String name) | { | return new ClassLoaderDomain(name); | } | | protected BaseClassLoader createClassLoader(ClassLoaderPolicy policy) | { | return new OSGiBundleClassLoader(policy); | } | when done, I could probably remove this hack | // [TODO] Should system packages be added as capabilities? | boolean isSystemPackage = syspackPlugin.isSystemPackage(packageName); | if (isSystemPackage == false) | { | OSGiPackageRequirement requirement = OSGiPackageRequirement.create(packageAttribute); | requirements.addRequirement(requirement); | } | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4251995#4251995 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4251995
