Since interceptors are not thread safe I would look at manipulating fields from a given thread with a jaundiced eye.

Re: how to re-init / update parameter of an interceptor during runtime?
Posted by mu...@aol.com.
An interceptor has access to application via ActionContext so it is easy to rig up. From anywhere in your application you can manipulate an entry in application and have the interceptor check if it matches the value it currently has. I still think it is an unorthodox approach though. It also costs you time as your intercept() method now has that extra check.

thx for your reply.
actually I am not going to change the param regularly.
this is more like "just in case I want to change the setting in the future".
thx
