David Lloyd commented on AS7-6215:
----------------------------------
Yes, however a JNDI name also unambiguously identifies a component. The difference
between this and {{@Resource}} would be that the dependency would be directly on the
component starting rather than (or in addition to) the binding. Of course we could also
go the simpler route and go deployment name + component name, but then we lose the
indirection that was desired in this JIRA.
Ability to declare a dependency on a service name

Key: AS7-6215
URL:
https://issues.jboss.org/browse/AS7-6215
Project: Application Server 7
Issue Type: Feature Request
Affects Versions: 7.1.3.Final (EAP)
Reporter: Brad Maxwell
Assignee: Stuart Douglas
Fix For: Open To Community
We have several use cases where we need dependencies between different deployments.
Such as
Singleton in ear1 which injects an ejb from ear2 using @EJB. At shutdown we need the
Singleton to call a method to clean up on the ejb, however the ejb is sometimes shutdown
before the Singleton. Using @DependsOn would allow the Singleton to depend on the EJB if
the EJB is in the same ear as the Singleton, however it is not.
There are other use cases where resources are injected and we need the resources to still
be deployed at shutdown so we can clean up the resources before they are undeployed.
Having a service name to depend on would be useful and if the name was configurable such
that it does not based on the exact name of the deployment, it would be useful as using
maven changes the deployment names when we rebuild and we do not want to have to change
the code each time we rebuild.
