Hi Friend,

Try the following code:

1)password.jsp:

<form method="post" action="chanPass.jsp">
<table>
<tr><td>Enter Old password: </td><td><input type="password" name="old"></td></tr>
<tr><td>Enter New password: </td><td><input type="password" name="new"></td></tr>
<tr><td>Enter Confirm password: </td><td><input type="password" name="confirm"></td></tr>
<tr><td><input type="submit" value="Change Password"></td></tr>
</table>
</form>

2)chanPass.jsp:

<%@page import="java.sql.*"%>
<%
String oldpass=request.getParameter("old");
String newpass=request.getParameter("new");
String confirm=request.getParameter("confirm");
if(newpass.equals(confirm)){
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test";, "root", "root");
Statement st=con.createStatement();
int i=st.executeUpdate("update login set password='"+newpass+"' where password='"+oldpass+"'");
out.println("Password changed successfully.");

st.close();
con.close();
}
catch(Exception exc){
System.out.println(exc);
}
}
else{
out.println("Your New Password and Confirm Password does not matches");
}
%>

Thanks
