i have a jsp page with jdbc connection and on first load it shows the data accurately but after that it shows empty tables i think 2nd time it loads from memory not from server
what is problem behind i don't know
ok here are the details
i have a servlet that maintains the session for a user that log in and then after creating the session the servlet redirect the user to a view page that is a jsp page and displays the existing records in DB
when the servlet redirects the page the jsp can show the records in but when i access this page from any other html page it is unable to display the records here is the code for jsp page to view.
<%@ page import="java.sql.ResultSet" %>
<%@ page import="java.math.BigDecimal" %>
<%@ page import="java.sql.SQLException" %>
<%@ page import="java.util.logging.Level" %>
<%@ page import="java.util.logging.Logger" %>
<%@ page import="iEHR.cDBProcessor" %>
