struts 2.x migration

[Martin Gainty <mg...@hotmail.com>]

Morning All-

Following the literature guidelines listed at
http://wiki.apache.org/struts/MigrationTools
I am hoping to deliver a (hopefully) comprehensive Struts.1 to Struts.2 migration strategy
Keeping in mind that Spring is being used for IOC of required objects (e.g. BeanFactories) and such

My question is the majority of migration suggestions is to use ActionWrapper to point backwards to Action 1.x classes using the Struts 1.x plugin defined in init method where there are 3 conversion steps
0)MessageResources
Action 2.0 TextProvider that retrieves messages from the Action 1.x MessageResources instance in the servlet context 
(understood as this exists in majority of localisation converters)

1)Struts 1 Action -> Struts 2 Interceptor -> Interceptor introduced to some manner of commons chain
Looking for clarification on where in the chain would this new Interceptor introduced and how is this determination made?

2)
ValidationInterceptor
LookUp the action in (existing) commons-validation objects loaded by an existing Action 1.x application
If there is validation logic in any method of a (non) commons-validation object how could one introduce this validation as a new 
commons-validation class and object (If handcoding is the only way then thats ok)

Many Thanks
Martin --
