Hi Friend,

Try the following code:

1)updateDatabase.jsp

<%@page import="java.sql.*"%>

<form name=myname method=post action="update.jsp">
<table border="1">
<tr>
<td><b><u>RollNo</u></b></td>
<td><b><u>Name</u></b></td>
<td><b><u>Class</u></b></td>
</tr>
<%try{

Connection conn = null;
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root";, "root");
ResultSet rs = null;
Statement st=null;
st=conn.createStatement();
rs = st.executeQuery("select * from employee where emp_id='2'");
while(rs.next()){ %>
<tr>
<td><input type="text" name="eid" value="<%= rs.getString("emp_id") %>"></td>
<td><input type="text" name="ename" value="<%= rs.getString("empName") %>"></td>
<td><input type="text" name="eadd" value="<%= rs.getString("empAddress") %>"></td>
</tr>
<%}
}
catch(SQLException e){}
%>
</table>
<input type="Submit">

2) update.jsp
<%@page import="java.sql.*"%>
<% String id=request.getParameter("eid");
String name=request.getParameter("ename");
String address=request.getParameter("eadd");
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 employee set empName='"+name+"', empAddress='"+address+"' where emp_id='"+id+"'");
out.println("Data is updated successfully.");
}
catch(Exception e){}
%>

Thanks
