Answer Posted / santosh anand
In struts , their is no facility of backward flow.Suppose we are in page 1 and when we submit it calls action mapping page2.Their may be lot of variable stored in session , which is available to page2.Now we wish to go page1 from page 2, for this we have to call the action mapping of page1. But struts flow is always in forward direction. So when we call page 1, values stored in session never get reversed.So it reduces the performance.To resolve this problem of struts, Their is a framework called Web Flow Nevigation Manager(WFNM) of Sourgeforge.net.This framework can be integrated with struts.
