We have a jsp application.

1)user.jsp:

<%@ page import="java.sql.*" %>
<html>
<head>
<script language="javascript">
function editRecord(id){
window.open('http://localhost:8080/examples/jsp/edituser.jsp?id='+id,'mywindow','width=500, height=350,toolbar=no,resizable=yes,menubar=yes');
}
function deleteRecord(id){
window.open('http://localhost:8080/examples/jsp/deleteuser.jsp?id='+id,'mywindow','width=500, height=350,toolbar=no,resizable=yes,menubar=yes');
}
</script>
</head>
<body>

<br><br>
<table border="1">
<tr><th>FirstName</th><th>LastName</th><th>Address</th><th>Email</th></tr>
<%
Connection con = null;
String url = "jdbc:mysql://localhost:3306/";;;
String db = "test";
String driver = "com.mysql.jdbc.Driver";
String userName ="root";
String password="root";

int sumcount=0;
Statement st;
try{
Class.forName(driver).newInstance();
con = DriverManager.getConnection(url+db,userName,password);
String query = "select * from register";
st = con.createStatement();
ResultSet rs = st.executeQuery(query);
%>

<%
while(rs.next()){
%>
<tr><td><%=rs.getString(2)%></td>
<td><%=rs.getString(3)%></td>
<td><%=rs.getString(4)%></td>
<td><%=rs.getString(5)%></td>
<td><input type="button" name="edit" value="Edit" style="background-color:#49743D;font-weight:bold;color:#ffffff;" onclick="editRecord(<%=rs.getString(1)%>);" ></td>
<td><input type="button" name="delete" value="Delete" style="background-color:#ff0000;font-weight:bold;color:#ffffff;" onclick="deleteRecord(<%=rs.getString(1)%>);" ></td>
</tr>
<%
}
%>
<%
}
catch (Exception e) {
e.printStackTrace();
}
%>
</table>
</form>
</body>
</html>

2)edituser.jsp:

<%@page language="java"%>
<%@page import="java.sql.*"%>
<form method="post" action="update.jsp">
<table border="1">
<tr><th>FirstName</th><th>LastName</th><th>Address</th><th>Email</th></tr>
<%
String id=request.getParameter("id");
int no=Integer.parseInt(id);
int sumcount=0;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test";, "root", "root");
String query = "select * from register where id='"+no+"'";
Statement st = conn.createStatement();
ResultSet rs = st.executeQuery(query);
while(rs.next()){
%>
<tr>
<td><input type="text" name="firstname" value="<%=rs.getString(2)%>"></td>
<td><input type="text" name="lastname" value="<%=rs.getString(3)%>"></td>
<td><input type="text" name="address" value="<%=rs.getString(4)%>"></td>
<td><input type="text" name="email" value="<%=rs.getString(5)%>"></td>
<td><input type="hidden" name="id" value="<%=rs.getString(1)%>"></td>
</tr>
<tr>
<td><input type="submit" name="Submit" value="Update" style="background-color:#49743D;font-weight:bold;color:#ffffff;"></td>
</tr>
<%
}
}
catch(Exception e){}
%>
</table>
</form>
</form>

continue..

3)update.jsp:

<%@page import="java.sql.*"%>
<%
String id=request.getParameter("id");
int no=Integer.parseInt(id);
String firstname=request.getParameter("firstname");
String lastname=request.getParameter("lastname");
String address=request.getParameter("address");
String email=request.getParameter("email");
try{
Connection conn = null;
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root";, "root");

Statement st=null;
st=conn.createStatement();
st.executeUpdate("update register set firstname='"+firstname+"',lastname='"+lastname+"',address='"+address+"',email='"+email+"' where id='"+no+"'");
out.println("Data is updated successfully");
}
catch(Exception e){
out.println(e);
}
%>

4)deleteuser.jsp:

<%@page language="java"%>
<%@page import="java.sql.*"%>
<%
String id=request.getParameter("id");
int no=Integer.parseInt(id);
int sumcount=0;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test";, "root", "root");
String query = "select * from register where id='"+no+"'";
Statement st = conn.createStatement();
st.executeUpdate("DELETE FROM register WHERE id = '"+no+"'");
out.println("Record is deleted successfully");
}
catch(Exception e){}
%>

For the above code, we have used following database table:

CREATE TABLE `register` (
`id` bigint(20) NOT NULL auto_increment,
`firstname` varchar(40) default NULL,
`lastname` varchar(40) default NULL,
`address` varchar(100) default NULL,
`email` varchar(100) default NULL,
PRIMARY KEY (`id`)
)
