hi rangers

i want to use a jsp page to authenticate a user

this is the code i wrote

<%@ page language="java" %>
<%@ page import"java.util.*,java.sql.*,javax.sql.*" %>

<%
String username =request.getParameter("username");
String password= request.getParameter("loginpassword");
%>

<%!
private String dbUserName = "root";
private String dbPassword = "idoreyin";
private String dbUrl = "jdbc:mysql://localhost:3306/filesdb";

Connection conn;
String loginName;
String loginpassword;
%>

<%

String sqlquery="SELECT * FROM login";
try {
Class.forName("com.mysql.jdbc.Driver");
System.out.println(JDBC driver loaded");
conn = DriverManager.getConnection(dbUrl,dbUserName,dbPassword);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(sqlquery);
while (rs.next()) {
loginName = rs.getString("username");
loginpassword = rs.getString("password");

if(username.equals(loginName) && password.equals(loginpassword)) {
%>

<html>
<body><table>
<tr><td>Click Here Store files:</td><td><input type="Submit" value="<jsp:include page="/StoreFilePage.jsp" />"></td></tr>
<tr><td>Retrieve Your files Here:</td><td><input type="Submit" value="<jsp:include page="/RetrieveFilePage.jsp" />"></td></tr>
</table>
</body></html>
<%
}
else {
%>
<jsp:forward page="/ErrorPage.jsp" />
<%
}
rs.close();
conn.close();

}
catch(ClassNotFoundException cnfe) {
cnfe.printStackTrace();

}
%>
