What do you think about converting all interceptors to be

Sounds neat. How would our current container interceptors dovetail
w/ interceptors that application developers create?
To start with there is currently no way for a user to do "dovetail"
in their interceptors at all. I do have a few ideas on how to allow
users to setup interceptors. I think in general we should allow
users to add interceptors to the head and tail of our container chain
(the chain that handles stuff like security and transaction). To do
this, the user should be able to set interceptors a the class and
package level as required by the spec. Then we should allow our
users to specify them at the ejb module, container and global levels.
Anyway, to keep things simple during the transition, I think we
should simply create our own interface with the following method:
Object invoke(InvocationContext invocationContext) throws Exception;
The big difference between this and the current interceptor interface
we are using from Geronimo is that it has a InvocationResult return
type and allows for a Throwable.
