Calling public class method from the servlet dopost() implementation

Question

Hi!
My application is a simple application where i wrote a JSP page to enter the USERNAME and PASSWORD. And this JSP will call a HttpServlet
with in which i am calling another Java class ValidateUser which will check aginst the Oracle Database table whether that Username and password combination exists and returns the user's name.
But when i am trying to call that method is throwing me an error. here is the typical code i wrote.
servlet
package isispack;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
import java.io.*;
public class Login extends HttpServlet{
public void doPost(HttpServletRequest req, HttpServletResponse res)
               throws ServletException,IOException{
String userId = req.getParameter("user_id");
String password = req.getParameter("user_pass");
// if uName is null .. user is not authorized.
String uName = Validate(userId, password);
and
Validate class
package isispack;
import java.sql.*;
import java.util.*;
import java.lang.*;
public class ValidateUser
public String ValidateUser(String inputUserid, String inputPwd) throws
SQLException{
     String returnString = null;
     String dbUserid = "isis"; // our Database user id
     String dbPassword = "isisos" ; // our Database password
     Connection con = DriverManager.getConnection("jdbc:odbc:JdbcOdbcDriver","isis","osiris");
     Statement stmt = con.createStatement();
     String sql= "select user_id from isis_table where user_id = '" inputUserid + "' and user_pass= '" + inputPwd +"' ;" ;
     ResultSet rs = stmt.executeQuery(sql);
     if (rs.next())
     returnString = rs.getString("user_id");
     stmt.close();
     con.close();
     return returnString ;
The ERROR
Error(18,18): method ValidateUser(java.lang.String, java.lang.String) not found in class isispack.Login
One more thing i forgot to tell you. I am trying to run this application on JDeveloper. Please helpme out if you can . Thank you.

Answer 1

OK! I made it static method
and tried to call the method as follows
String uName = ValidateUser.ValidateUser(userId, password);
even if i create the instence and
ValidateUser Validate;
then call
String uName= Validate.ValidateUser(userId,password)
In either case is giving me the following error.Tarun, am new to Java programming, please help me out. And can you please tell me where can i find things in consise to brush up my fundamentals?.
Error(18,43): unreported exception: java.sql.SQLException; must be caught or declared to be thrown
