Hi,all
I have a jsp page which pass a value to a servlet, the servlet then need go
to the database and select somevalues based on the parameter passed from the
jsp page as the where clause. the values will be stored in a vector. after
that, the servlet will be redirect back to the jsp and passing the vector
back to jsp.
I encountered two questions here:
Q1. *** regarding page redirect ***
I tried following code in my servlet to do the redirect. it does not
redirect to the target at all.
String url = res.encodeRedirectURL("http://dre.col.loc/formular/combo.jsp");
res.sendRedirect(url);
I also tried:
RequestDispatcher x =
getServletContext().getRequestDispatcher("http://dre.mamsi.loc/formular/combo.jsp");
x.forward(req,res);
it does not work either.
Q2. **** regarding pass data from servlet back to Jsp ***
other than put the vector in a session variable, how can I put the vector to
the request and send back to the jsp?
using response.setAttribute("name", value)?? then will the redirect make the
attribute lost?
Could someone give me a hint???
Regards
Helen
