- As noted earlier, clients do not see direct references to bean implementations
- This allows the container provider to create a point of interception
- Basically, no call goes into the bean implementation without passing through the point of interception
- The standard does not dictate how to implement the point of interception
- There are several possibilities, which one is used should be transparent
- One architecture simply involves a second object, generated by the container, that delegates business methods the an instance of the bean implementation
- References to this wrapper object are given to the client
- This wrapper is the point of interception
