Until Ales and I write the non-flat deployment strucutre for JBoss AS, this is a moot point really, as there is only one. Then you call BeanManager manager = bootstrap.getManager(beanDeploymentArchive); Note that normally MC beans can't access stuff inside deployments tho. I would assume we will end up with a structure like this in JBoss AS: EAR Deployment EJB JAR BDA -> Server lib/ virtual BDA WAR BDA -> Server lib/ virtual BDA -> EJB JAR BDA (where -> denotes accessibility). So you would *always* put the MC beans in the Server lib/ virtual BDA.

The registry mentioned currently stores the context names and web beans Bean implementations, but we probably need to take scoped controllers into account there. So how do we determine which controller should be used for a particular bean manager? For MC->WB injection, the MC beans need to be deployed first so that they are registered with the bean manager. For WB->MC injection, the WB beans need to be deployed first since the MC WebBeansKernelControllerContext gets initialised with the bean manager on creation. I think the MC beans needing to be deployed first is pretty definite, but it would be good if the bean manager to be used for WB->MC could be determined somehow at a later stage. I am currently ignoring the fact that there are other Bean implementations than SimpleBean, and also not handling WebBeansKernelControllerContexts for bean factories View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4252251#4252251 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4252251

[JBoss OSGi Development] - Fundamental class space issue

by thomas.diesler＠jboss.com

Please consider this A imports X B imports X Can X load a class from A or B? Can A load a class from B and vice versa? I believe both is true. https://jira.jboss.org/jira/browse/JBOSGI-142 This works with Felix, but fails with the MC Framework.

[jBPM Development] - Re: DeploymentAdaptor: duplicated process deployment since c

by kukeltje

Marko, Explicit versioning of the jpdl.xml files should prevent multiple deployments as I mentioned in my initial reply. Could very well be that that is not in place yet (and that Bernd has some ideas in this direction) btw, *anything* not in the user guid but in the dev guide is still under development. So you could run into other issues as well as you use these View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4252217#4252217 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4252217

[jBPM Development] - Re: DeploymentAdaptor: duplicated process deployment since c

by SNy

Heh, OK, I know it's still being worked on but wanted to bring this specific point up. I first thought about filing a jira issue, but then decided against it and posted here instead. FWIW, I worked around it in my local version by adding a flag to the addResourcesFromZipInputStream() method to tell it to NOT add any .jpdl.xml files. Then I included both calls in the deploy() sequence so it now adds all resources except the process descriptors and then adds the one process descriptor it has been invoked for.
