Thank you very much for the very prompt reply. If it possible, then How would I differentiate between struts1 action classes and struts2 action classes (apart from ActionSupport)?
Right now, I am trying to use struts2 action in the flow of struts1 action classes. How do I map action classes? I have struts-config.xml and struts.xml. What would be the controller in this case? Please let me know ... Thanks, Sanday Alberto A.
