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" %>

It smells like threadsafety/scoping problem. You've declared the ResultSet and DBProcess as instance variable of the JSP using <%! %> scriptlet declarations, so it's been shared among all HTTP requests. I am not sure about the DBProcess, but this is certainly a bad idea for ResultSet (and also for Connection and Statement by the way). How the DBProcess is been used in the remnant of the code is also pretty scary, e.g. DBProcess.statement.executeQuery(). Is the Statement really a public field? I don't know how the class' internals look like, but yes, this smells too much like threadsafety/scoping problem.
Also, this 90's style writing of HTML and using scriptlets in JSP really don't suit a "Copyright 2010" application. Are you reading the right tutorials/books?
beside those issues pointed out by BalusC,
base on the described symptom "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" and code "if(request.getAttribute("dbrec") != null) ".
My prime suspect for the issue's cause is the use of request.getAttribute("dbrec")
for those direct access from other html page, this value likely to be null. I suspect for redirect case, there may be some code that perform request.setAttribute("dbrec",....)

Can someone out here point out the reason why this is happening or what I have missed or done wrong?
iText 5.5.13.2 is the old version of iText product and it's not supported anymore. Most likely there are some not supported functionality in the html or css. I can guess that float properties are not supported. Probably there are issues with percentage width. You can try to play around with your html and css files to try to make pdf look acceptable, but the easiest way is to use the newest version of iText product which is iText 7
I am not sure why <LINK REL="STYLESHEET" TYPE="text/css" HREF="C:/apache-tomcat-8.5.24/webapps/print.css"/> is not working, My css is not affecting nor supporting my html code and java code I am using to convert as pdf is this method, there is no error in PDF. Is there something I am missing?

I'm trying to link a product from the category.jsp page to its own product.jsp page. When I click on a given product on the category page, the link in the browser displays perfectly as supposed to: http://localhost:8080/ecommerce/product?389 but the issue: I receive a HTTP Status 404 - Not Found error. I know it's because it's not finding the page, but after trying several solutions... I seem to not be able to find the piece of code that would make a difference... Any help would be much appreciated
The Controller Servlet:
package controller;
import cart.ShoppingCart;
import wishlist.Wishlist;
import entity.Category;
import entity.Product;
import java.io.IOException;
import java.util.Collection;
import javax.ejb.EJB;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import session.CategoryFacade;
import session.ProductFacade;
public class ControllerServlet extends HttpServlet {
#EJB
private CategoryFacade categoryFacade;
#EJB
private ProductFacade productFacade;
#Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String userPath = request.getServletPath();
HttpSession session = request.getSession();
Category selectedCategory;
Product selectedProduct;
Collection<Product> categoryProducts;
// if product page is requested
if (userPath.equals("/product")) {
// get productId from request
String productId = request.getQueryString();
if (productId != null) {
// get selected product
selectedProduct = productFacade.find(Short.parseShort(productId));
// place selected product in session scope
session.setAttribute("selectedProduct", selectedProduct);
}
This is the code from the category.jsp to call the product:
<img class="img" src="${initParam.productImagePath}${product.name}.jpg">
Full Category.jsp:
<table style="text-align: left; width: 100%;" border="0" cellpadding="0" cellspacing="0">
<c:forEach var="product" items="${categoryProducts}" varStatus="iter">

<br>

</c:forEach>

This is the Product.jsp (destination page):

Solved the issue myself. I forgot to add the parameter in the web.xml:
<servlet-mapping>
<servlet-name>ControllerServlet</servlet-name>
<url-pattern>/product</url-pattern>
</servlet-mapping>

In my project, i want to make a jsp page faded when a button is clicked and show the parent(behind) page.
<html>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
<style type="text/css">
<!--
.style1 {
font-family: Arial, Helvetica, sans-serif;
font-weight: bold;
font-size: 12px;
}
-->
</style>
<link href="css/buttons.css" rel="stylesheet" type="text/css"/>
</head>
<body>
<form name="form1" method="post" action="analystServlet">
<table width="100%" border="0" cellspacing="1" cellpadding="1">
<tr>
<td> </td>
<td> </td>
</tr>
<tr>
<td><span class="style1">Choose Source</span></td>
<td><select name="source">
<option>Excel</option>
<option>Database</option>
</select></td>
</tr>
<tr>
<td><input type="hidden" name="id" value="494"/></td>

</div></td>
</tr>
</table>
</form>
</body>

You can do it using ajax/jquery only
function closeMe()
{
window.opener.location.reload(true); // reload parent page
window.close(); // close this page
}
$("#submitbtn").click(function(e) {
e.preventDefault();
var params = {
// here pass form parameter
};
$.ajax({
type: "POST",
url: "/analystServlet",
data: params,
success: function(data){
$('body').css("background", "rgba(0,0,0,0.5)").fadeOut("slow");
setTimeout(function () {
closeMe();
}, 1000); // 1000 = 1 secs
}
}); // end of $.ajax()
