                 Key: JS2-1202
                 URL: https://issues.apache.org/jira/browse/JS2-1202
             Project: Jetspeed 2
          Issue Type: Bug
          Components: Assembly/Configuration, Deployment
    Affects Versions: 2.2.1
         Environment: WebSphere 6.1
            Reporter: Woonsan Ko
            Assignee: Woonsan Ko
             Fix For: 2.2.2


When deploying jetspeed-layout local PA by extracting all onto /jetspeed/WEB-INF/apps/jetspeed-layout, it fails to register the local PA with the exception messages below. [Exception message].

The bean, "deploymentManager" (typeof o.a.j.deployment.impl.StandardDeploymentManager) in deployment.xml, tries to register the scanned local PAs from the staging directory as soon as it is initialized as a bean.
The registration process passes through o.a.j.tools.pamanager.PortletApplicationManager#grantDefaultPermissions(String), and it goes to o.a.j.security.util.ojb.JetspeedPrincipalConcreteClassRowReader#extractOjbConcreteClass(ClassDescriptor, ResultSet).
The problem, however, is that the PortletApplicationManager doesn't have a chance to be called on the static method, #setJetspeedPrincipalManagerProvider(JetspeedPrincipalManagerProvider), which is supposed to be called during the *bean initializations* in "static-bean-references.xml".
With the current assembly configurations, it's not guaranteed that the beans in static-bean-references.xml are initialized before!

This kind of static initialization during the bean initialization could produce other problems potentially as well; so we need to find a way to avoid this kind of complexities (which seems to have been introduced after 2.2.0 security provider enhancements.)
However, I think we can postpone refactoring for this now.

Anyway, to resolve this problem, one simplest solution I have in mind is to make the "deploymentManager" bean in deployment.xml start only after the spring application context finished initialization on all the beans.
Also, to isolate the ""deploymentManager" from the spring framework API, it is possible to make a utility bean to invoke "start" method by implementing org.springframework.context.ApplicationListener.
