[jboss-as7-dev] cl.getResources() doesn't work from module-based code

[David M. Lloyd]

If this is in the context of a deployment, then yes the TCCL will be the 
class loader of the deployment and that's the one you should use if you 
want the *combination* of services provided to the deployment by the 
container *plus* the services defined in the deployment itself.  But 
you're using an intermediate aggregate module (which we don't normally 
do for AS services).  This means in order for it to work you have to do 
two things:

1. Set the dependencies whose services must be visible to the deployment 
to services="export"
2. When the module is imported into the deployment (presumably via the 
deployer), it has to import services from that dependency as well.

Now if you don't want to actually load service implementations from the 
deployment itself then you definitely shouldn't be using TCCL; in this 
case you'd just use your "skeleton key" module's class loader.
