Package org.jboss.as.weld

Class WeldBootstrapService

  • All Implemented Interfaces:
    org.jboss.msc.Service
    public class WeldBootstrapService
extends Object
implements org.jboss.msc.Service
    Provides the initial bootstrap of the Weld container. This does not actually finish starting the container, merely gets it to the point that the bean manager is available.

    • Field Detail

      • SERVICE_NAME

        public static final org.jboss.msc.service.ServiceName SERVICE_NAME
        The service name that external services depend on

      • INTERNAL_SERVICE_NAME

        public static final org.jboss.msc.service.ServiceName INTERNAL_SERVICE_NAME
        The actual service name the bootstrap service is installed under.

        The reasons for this dual service name setup is kinda complex, and relates to https://issues.redhat.com/browse/JBEAP-18634 Because Weld cannot be restarted if an attempt is made to restart the service then we need to bail out and restart the whole deployment.

        If we just do a check in the start method that looks like: if (restartRequired) { doRestart(); return; } Then the service startup will technically complete successfully, and dependent services can still start before the restart actually takes effect (as MSC is directional, it keep starting services that have all their dependencies met before it start to take services down).

        To get around this we use two different service names, with the service that other services depend on only being installed at the end of the start() method. This means that in the case of a restart this will not be installed, so no dependent services will be started as they are missing their dependency.
