{
getServletContext().getRequestDispatcher("/vendorcp.jsp").forward(request,response);
request.setAttribute("n",n);
}

ofcourse.. you are forwarding request to vendorcp.jsp then you set the value in request.. so , how you will get the value in next page?

Friend.. then what should i do in order to refresh the page after the DB function finished... Please let me know...

What do you want to be displayed after the DB has been updated ?
A new blank form ? Then

if (rajkumar != 0 && rajasekar != 0 && fpass != 0) {
request.getRequestDispatcher("/vendorcp.jsp").forward(request,response);
}

should work (assuming vendorcp.jsp is the form jsp which displays blank if no params are set in request).
Else, forward to a message JSP in which you inform of the successfull DB update.

But i need the request Attribute to set the object name to display a message like Data added to the vendorcp.jsp, along with blank jsp page...
I currently use ${n.result} to display that. So i need req.setAttribute("n",n/*This n is used to call result method where i have a string with value as Data added*/);

Is there other ways to accomplish that?
