Package org.camunda.bpm.container.impl.jboss.service

Class ProcessApplicationStartService

java.lang.Object

org.camunda.bpm.container.impl.jboss.service.ProcessApplicationStartService

All Implemented Interfaces:

org.jboss.msc.Service, org.jboss.msc.service.Service<ProcessApplicationStartService>, org.jboss.msc.value.Value<ProcessApplicationStartService>

public class ProcessApplicationStartService
extends Object
implements org.jboss.msc.service.Service<ProcessApplicationStartService>

This service is responsible for starting the MscManagedProcessApplication service.

We need this as an extra step since we need a declarative dependency on the ProcessApplicationComponent in order to call the getName() method on the ProcessApplication. The name of the process application is subsequently used for composing the name of the MscManagedProcessApplication service which means that it must be available when registering the service.

This service depends on all ProcessApplicationDeploymentService instances started for the process application. Thus, when this service is started, it is guaranteed that all process application deployments have completed successfully.

This service creates the ProcessApplicationInfo object and passes it to the MscManagedProcessApplication service.
