Hi Umesh, Paul and Martin,
Thanks a lot for you help. Finally using session aware I could save and
retrieve the shopping cart across pages. PFB the code :
To save :
Use implements SessionAware
public void setSession(Map sessionMap) {
map = sessionMap;
map.put("ShoppingCart", getCart());
To retrieve :
HttpServletRequest request = ServletActionContext.getRequest();
setCart((Cart)request.getSession().getAttribute("ShoppingCart"));
How to clean up the session : session.removeAttribute ("ShoppingCart") ??
Thanks,
Srineel
