The given code retrieve data from database and display in the html table. At each row, there is a button which consists of that particular id. When the user clicks the particular edit button, that data will get shown in another page and allow the user to update the record.
1)application.jsp:
<%@ page import="java.sql.*" %>
<html>
<head>
<script language="javascript">
function editRecord(id){
var f=document.form;
f.method="post";
f.action='edit.jsp?id='+id;
f.submit();
}
</script>
</head>
<body>
<br><br>
<form method="post" name="form">
<table border="1">
<tr><th>Name</th><th>Address</th><th>Contact No</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 employee";
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:green;font-weight:bold;color:white;" onclick="editRecord(<%=rs.getString(1)%>);" ></td>
</tr>
<%
}
%>

}
catch(Exception e){
e.printStackTrace();
}
%>
</table>
</form>
</body>
