Resource Adapter Classloading 

Use

When a resource adapter is deployed, the system associates it with a classloader. It is used to initialize the adapter’s classes. Resource adapter classloading also defines the access of other components to a resource adapter.

Features

Each application deployed on the AS Java has its own classloader. If you deploy a resource adapter as a standalone component, the AS Java regards it as an application with only one module in it. If you deploy a resource adapter as part of a larger application, it is added to the application’s classloader. Thus, each resource adapter deployed on the AS Java has its own classloader.
