[jboss-jira] [JBoss JIRA] Commented: (AS7-1656) Binder services should not be ON_DEMAND

[Paul Ferraro (JIRA)]

    [ https://issues.jboss.org/browse/AS7-1656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12624356#comment-12624356 ] 

Paul Ferraro commented on AS7-1656:
-----------------------------------

I'm not sure this is really a problem.  There are several mechanisms to demand the jndi binding, @Resource injection, <resource-ref>, etc.

What I'd hate to lose is the coupling of the jndi resource to the application lifecycle.  One solution would be to introduce an additional start-mode for infinispan caches that distinguishes between LAZY and ON_DEMAND.  LAZY could install the binder service using ACTIVE mode, where the cache container gets started lazily, while ON_DEMAND would preserve the current behavior.  This way, if some application needs to perform a jndi lookup without a mechanism for demanding the binding to start, there is a configuration option that supports this without having to resort to eagerly starting a cache.

> IF a binder service is registered as ON_DEMAND then the item will not be available for lookup in JNDI until something as expressed a dependency on it. This means that it will work for resource injection, however will fail for manual JNDI lookups. 
> If lazy startup is required the binder service should use a ManagedReferenceFactory that starts the lazy service and blocks until the lazy service is available.
