[jboss-as7-dev] Is there a way for a core module to load a class from a war

[Jason Greene]

You can instantiate a class in another module if you have a classloader or a module name for that module. This could be done by adding a registration method that takes a classloader. Alternatively if you are sure the incoming calls are all coming in from an EE context which contains the classes (and not system code) you can use TCCL.

Lastly you can switch to some kind of declarative model and add a deployment processor which handles registration as part of deployment.
