2) gettable.jsp:

<%@page language="java" import ="java.sql.*" %>
String val[] = request.getParameterValues("val");
String st="";
for(int i=0;i<val.length;i++){
String str[]=st.split(",");
for(int i=0;i<str.length;i++){
ResultSet rs = null;
String buffer="";
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","root");
Statement stmt = con.createStatement();
for(int i=0;i<str.length;i++){
String ide=str[i];
int id=Integer.parseInt(ide);
rs = stmt.executeQuery( "SELECT * FROM employee WHERE empid='"+id+"'");

buffer=buffer+"<table border><tr><td>"+rs.getString("empid")+"</td><td>"+rs.getString("name")+"</td><td>"+rs.getString("address")+"</td></tr></table>";


But,I want more help from you.

In my program , i have given to link to different jsp pages. Suppose it contains two links with two different jsp pages.

Both jsp pages contains differents database tables, n it contains same checkboxes.

So, from above code, i can display selected checkbox on same page. It works...

But when i go to another page link containing same format, it does not display previous page's selected checkboxes.

So, i want such output, which can show previous pages selected checkbox as well as i aslo include next page's selected checkbox in display list on same pages respectively.( i don't know exactly, but can we store it in session and in collection so that we can display all selected checkbox)

Please,please help me... waiting for your reply
