How to control glassfish module startup order

I have several web modules. There are dependency between them, say during startup, module B will use MBean exposed by module A. How to configure glassfish to enable it start them by specific order? Or is it possible to configure it to load them concurrently.

I searched quite a lot via google, but not result.

BTW, I'm using glassfish-2

This post indicates that initial deployment order defines the startup order. I have found (on Glassfish 3) that the order is stored in domain.xml so you can swap entries in there.
