Here is a code that accepts the current password, New password and conform password from the user and change the password.

1)change.jsp

<html>
<script>
function validate(){
if(document.f.new.value!=document.f.confirm.value){
alert("New Password and Confirm Password should be same! Re-enter confirm-password!");
document.f.confirm.value="";
return false;
}
return true;
}
</script>
<form name="f" action="changePassword.jsp" method="post" onsubmit="return validate();">
<table>
<tr><td>Current Password</td><td><input type="password" name="current" ></td></tr>
<tr><td>New Password</td><td><input type="password" name="new"></td></tr>
<tr><td>Confirm Password</td><td><input type="password" name="confirm"></td></tr>
<tr><td><input type="submit" value="Change Password"></td></tr>
</table>
</form>
</html>

2)changePassword.jsp

<[email protected] import="java.sql.*"%>
<[email protected] import="java.io.*"%>
<%
String currentPassword=request.getParameter("current");
String Newpass=request.getParameter("new");
String conpass=request.getParameter("confirm");
String connectionURL = "jdbc:mysql://localhost:3306/test";
Connection con=null;
String pass="";
int id=0;
try{
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection(connectionURL, "root", "root");
Statement st=con.createStatement();
ResultSet rs=st.executeQuery("select * from login where password='"+currentPassword+"'");
if(rs.next()){
id=rs.getInt(1);
pass=rs.getString(3);
}
System.out.println(id+ " "+pass);
if(pass.equals(currentPassword)){
Statement st1=con.createStatement();
int i=st1.executeUpdate("update login set password='"+Newpass+"' where id='"+id+"'");
out.println("Password changed successfully");
st1.close();
con.close();
}
else{
out.println("Invalid Current Password");
}
}
catch(Exception e){
out.println(e);
}
%>
