Prioritizing @Singleton & @WebServlet with @Priority #17

Open

Description

@glassfishrobot

Following the thread http://java.net/projects/javaee-spec/lists/users/archive/2012-12/message/17

@priority is used to priorityze interceptors in Java EE 7. It would be interesting to spread this feature to other components in Java EE 8, for example @singleton & @WebServlet.

@Singleton
@Startup
@Priority(100)
public class MyVeryFirstSingleton {}

@Singleton
@Startup
@Priority(4500)
public class MyVeryLastSingleton {}

    Yes, please feel free to raise this issue with those expert groups when we enter Java EE 8.

    Just to clarify.... Did you mean for example prioritizing amongst the startup of other singletons, or prioritizing more globally (i.e., the whole startup order of the application)? If the former (i.e., prioritizing singletons amongst singletons; etc.), could you please re-file the appropriate issues for the individual expert groups.

    The title of the JIRA is maybe not appropriate, as it could have been "Being able to prioritize Java EE components when ordered is needed". So yes, this topic is first to be debated in the Java EE expert group, and then push it to the other specs.

    As discussed with Linda, here is how she rephrase it :

    (1) Various expert groups should evaluate how they can leverage
    the @priority annotation. For example, EJB could use it to
    order the startup of singleton beans; Servlet could use it to
    order the invocation of Filters;.... [I.e., the annotation would be
    used to order within particular managed classes, beyond those we
    already support its use on.]

    OR

    (2) @priority could be used to prioritize the startup order of
    the application. For example, EJB singletons would be started
    before the JPA EntityManagerFactory was initialized, ....
    [I.e., the annotation would be used to order more globally within
    the application.]

    I think we should, at least, do 1) but of course 2) will be better
