Hi,
this is my framework problem, for certain reasons using default
servlet session is disabled, i thought it is struts error. sorry to all.
as session is disabled... can i do the same operation with
request.setAttribute(...) ?
can any one tell me where the values added in session are read and used in
new action, in this code?
