Login.java

package foo;
import java.sql.*;

public class Login {

private String username = "";

public void setUsername(String username) {
this.username = username;

public void setPassword(String password) {
this.password = password;
}

public boolean authenticate(String username2,
String password2) {
String query="select * from Registration;";
String DbUserName="";
String DbPassword="";
String finalUser="";
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection
con=DriverManager.getConnection("jdbc:odbc:registe r");
Statement stat=con.createStatement();
ResultSet rst=stat.executeQuery(query);
while(rst.next())

{
DbUserName=rst.getString("UserName");

DbPassword=rst.getString("password");

if (username2.equals(DbUserName) &&
password2.equals(DbPassword)) {

break;
}

}
return true;
}catch(Exception e){

e.printStackTrace();
return false;
}
}}

success.jsp

<html>
