In my struts.xml I have URL link /app/test/ maps to test() method. I found when I type /app/test?name=xyz&ID=ABC
it went throught the prepare() method, but inside the method it recognizes "name" and "ID" as null, i.e. the values of name and id are not bounded to the instance variable yet. However, in "test()" these values are avaiable already.

Can you tell me why ? And how can I do some cleaning type work in "prepare()" that needs to use instance variables ?

secondly, if instance variables are not available in prepare(), are session variables available ?

Thank you.

Prepare method will be called before you action triggers, so using the parameterAware in prepare method read request Parameters and assign the values. To take care order of interceptors. ServletConfig should be before PreparableInterceptor.
