No, this is not possible. The closest that I can think of is to do
explicit jndi lookup(s) to get references of all such session beans
and add to the collection.
Note that you can use @Resource and use a custom ObjectFactory, but
the ObjectFactory will have to do multiple lookup(s) itself to
populate the collection.,
