"invalid page number 1" error connecting to database with UCanAccess

Question

I am following this tutorial, just that I changed the connection to UCanAccess.

I imported all jars, but I am still getting an error, I have no idea what is the problem

The Error

And the Code

package servlets;


import java.sql.*;


public class ConnectionManager {

   static Connection conn;
   static String url;


   public static Connection getConnection()
   {
     try
     {           

        Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
          String url="jdbc:ucanaccess://C:/workspaceWeb/LoginExample/src/servlets/usersetup.db";

         System.out.println("blabla");
         conn = DriverManager.getConnection(url,"UserName", "PassWord"); 
         System.out.println("commecla");

     }

     catch (SQLException | ClassNotFoundException ex)
     {
        ex.printStackTrace();
     }
return conn;

}
}

Umm, "usersetup.db" wouldn't happen to be a SQLite database would it? If so, then there is no way that UCanAccess can open it. UCanAccess can only open Access databases (.accdb, .mdb, or related). — Gord Thompson, Sep 26 '16 at 11:15
nvm found out at https://www.tutorialspoint.com/sqlite/sqlite_java.htm, didnt knew different databases have different connection methods — Marcus Y, Sep 26 '16 at 11:25

You are trying to open a SQLite database with UCanAccess, and that won't work. UCanAccess can only open Access databases (.accdb, .mdb, or related). To work with a SQLite database you will need to use something like Xerial's SQLite JDBC Driver.
