Inter-EAR dependencies on Cloud Platform

Hi developers,

I need to deploy 2 EAR archives on the Cloud Platform.

The first one (LibraryEAR) has a lot of .jars in his lib folder: they change rarely and will be deployed just once

The second (ApplicationEAR) has my application in it, and is deployed many times a day.

I would like to define a runtime dependency from ApplicationEAR to LibraryEAR so that the classes in the jars get resolved correctly.

In my understanding this is an vendor-specific feature: for instance JBoss has its own descriptors and Netweaver On-premise does this with the DC model.

How is this dependency specified on the Cloud Platform?

Thanks and regards

Vincenzo
