Dhanakumar,1) Struts offers various sets of interceptors. One of them must
be params-prepare-params (params is called twice). For these requests in
question you could use that interceptor stack.
2) It is not advisable to change the struts.xml for standard interceptor
sets. Instead create another stack "my-stack" and change whatever you want
with it :)
Helps?
