Dear Greg Lindholm, Thanks so much. I could make it work with preresultlistener. Really Cool.
Dear Lukasz Lenar, Thanks so much. So, I understand that the result has been created before it reaches the post invoke in interceptor. But, I still wonder with a question as to why this cannot happen simply? I mean, without a preresultlistener. Ok. My next question is as follows (in further to the same post invoke in interceptor): (I want to illustrate with a simple example) 1) I want to decorate a string property of action. 2) The interceptor will add for example, "$" before the value of property. 3*) I am against adding any method in action. No logic will go in action class. 4) My interceptor will pick up the action property, modify it in invoke() method, itself. 5) So, when I want to decorate, I add my interceptor in struts.xml for this action. 6) My interceptor needs to pick up a property from action and decorate it. (In post action invoke()) Please let me know. Thanks so much.
