Subject [jira] Closed: (GERONIMO-513) jndi refs should result in dependencies, optionally

David Jencks closed GERONIMO-513:
---------------------------------

    Resolution: Fixed

After more thought and discussion with Dain we are trying a simpler implementation.  All web
app modules will depend on all ManagedConnectionFactory gbeans and all ejbs in the ear.  This
will make sure that all possible jndi references for a servlet are started before the servlets
init method is called.  This is overkill, but does allow for possible future use of non- java:comp
jndi contexts that are so popular (even though we don't currently support that) and eliminates
trying to figure out how to unwrap circular ejb dependencies.

Before implementing this I implemented a jndi-ref to dependency solution; I'll attach that
as well for future reference.

> After non-reference gbean dependencies (GERONIMO-512) are implemented, jndi refs should
result in creating these dependencies.  They need to be optional to take account of (at least)
these scenarios:
> 1. circular ejb references A uses B uses A.  
> 2. An ejb has 2 resource refs: if the first one isn't available, it tries the backup
second one.
> So, the naming schema needs an optional <optional/> tag to prevent a ref from turning
into a dependency.
