[JBoss OSGi Development] - Re: Autostart bundles when deployed in JBossAS

by thomas.diesler＠jboss.com

There is an approach from Ales, which introduces a new state 'Reset' and resets the context to Described when it cannot get resolved. http://anonsvn.jboss.org/repos/jbossas/projects/demos/microcontainer/trun... This approach fails however for bundles with self dependencies. I also have made an attempt which involves a LifecycleCallbackItem and uses the PackageAdmin in a seperate Thread to resolve and progress bundles http://anonsvn.jboss.org/repos/jbossas/projects/jboss-osgi/projects/runti... | public void deploy(DeploymentUnit unit, OSGiBundleState bundleState) throws DeploymentException | { | bundleState.getBundleManager(); | | ControllerContext context = unit.getAttachment(ControllerContext.class); | DependencyInfo di = context.getDependencyInfo(); | | LifecycleCallbackItem lifecycleCallbackItem = new LifecycleCallback(unit); | di.addLifecycleCallback(lifecycleCallbackItem); | } | | private class LifecycleCallback implements LifecycleCallbackItem | { | private DeploymentUnit unit; | private PackageAdmin packageAdmin; | private DeployerClient deployerClient; | | public LifecycleCallback(DeploymentUnit unit) | { | this.unit = unit; | | OSGiBundleState bundleState = unit.getAttachment(OSGiBundleState.class); | BundleContext sysContext = bundleState.getBundleManager().getSystemContext(); | ServiceReference sref = sysContext.getServiceReference(PackageAdmin.class.getName()); | packageAdmin = (PackageAdmin)sysContext.getService(sref); | | deployerClient = unit.getAttachment(MainDeployer.class); | } | | public void uninstall(ControllerContext ctx) | { | OSGiBundleState bundleState = unit.getAttachment(OSGiBundleState.class); | unresolvedBundles.remove(bundleState); | } | | public void install(ControllerContext ctx) throws Exception | { | Runnable runnable = new Runnable() | { | public void run() | { | try | { | // [TODO] remove this hack and find a way to trigger | // PackageAdmin after the context has been deployed | Thread.sleep(100); | } | catch (InterruptedException e) | { | // ignore | } | | OSGiBundleState bundleState = unit.getAttachment(OSGiBundleState.class); | | // Add the new bundle to the list of unresolved | unresolvedBundles.add(0, bundleState); | OSGiBundleState[] unresolved = new OSGiBundleState[unresolvedBundles.size()]; | unresolvedBundles.toArray(unresolved); | | // Try to resolve all unresolved bundles | packageAdmin.resolveBundles(unresolved); | if (bundleState.getState() != Bundle.RESOLVED) | log.info("Unresolved: " + bundleState); | | for (OSGiBundleState aux : unresolved) | { | if (aux.getState() == Bundle.RESOLVED) | { | unresolvedBundles.remove(aux); | | try | { | // When resolved progress to INSTALLED | String name = aux.getDeploymentUnit().getName(); | deployerClient.change(name, DeploymentStages.INSTALLED); | } | catch (DeploymentException ex) | { | log.error(ex); | } | } | } | } | }; | new Thread(runnable).start(); | } | | public ControllerState getWhenRequired() | { | return new ControllerState(getStage().getName()); | } | | public ControllerState getDependentState() | { | return null; | } | | public Object getBean() | { | return null; | } | } | The separate Thread was necessary because the context is still installing when the PackageAdmin tries to progress to stage CLASSLOADER. Conceptually, there are two passes needed for bundle deployment. Phase #1: Install bundles (reqstage == DESCRIBE ) Phase #2: Resolve & Start bundles (reqstage == INSTALLED) Perhaps a callback for when the Phase #1 is needed or is there any other way to get rid of that Thread that starts Phase #2?

[JBoss OSGi Development] - Autostart bundles when deployed in JBossAS

by thomas.diesler＠jboss.com

The basic issue is that a bundle deployment when put in requiredStage = DeploymentStages.DESCRIBE it will only progress to Bundle.INSTALLED, hence the bundle with not get RESOLVED nor STARTED. When requiredStage = DeploymentStages.CLASSLOADER or above, the bundle can start when all its dependencies are resolved. The bundle deployment will however fail, if it has unresolved dependencies. The desired behaviour is: Bundles with unresolved dependencies get INSTALLED without error. Bundles with resolved dependencies get STARTED without error. A bundle that could only get INSTALLED (but not RESOLVED) gets STARTED when it's dependencies can be RESOLVED.

[jBPM Development] - Re: values in example.identities.sql for JBPM4_ID_USER do no

by nystony

Tom, I just installed 4.1 on jboss 5.0GA, but when it is deployed, the database schema is created but no users. I found your script in this forum; but why isn't it in the installation. I see an Ant target to create the schema but it doesn't populate the users database bedankt Tony View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4253503#4253503 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4253503

[JBoss Remoting Development] - How to know that a remote ejb is droped from the Server

by tonimenen

I created an remote ejb... And i want to know if the ejb is remove when I do the bean.remove(); I have checked in the jmx-console ( org.jboss.ejb.StatelessSessionContainer) of may ejb, and I can see statistics of create count is bean increasing, but RemoveCount is always 0. It is mean that my ejb is never removed ? By the other hand in the org.jboss.ejb.plugins.StatelessSessionInstancePool, i can see Currentsize = 50 and Maxsize=100 ? Can anyone interpret this data ?

[JBoss AS Development Deployment Framework] - List of all deployers

by radu.cirstoiu

Hello I'm trying to get a list of all deployers (in order to listen to start_notification), but calling getDeployers() in MainDeployer renders nothing. Is there perhaps another way? Thanks!

by jesper.pedersen

Applied with minor modifications, since the JDK5 build didn't work. There are findbugs warnings on AbstractPool - these needs to be resolved. Thanks, again !
