Hi everybody I am trying to do a basic library system.
the problem is:
I downloaded MySQL driver (connector/j) I copied .jar in CLASSPATH/jre/lib/ext
but it didn't work, I tried to copy the .jar in the directory of my application where I have my .java (or .class in execution time)
but when I execute the application the following error appear:

java.lang.ClassNotFoundException: Resource not found:
com/mysql/jdbc/Driver.class

this is the code:

Code:

try{
     
Class.forName("com.mysql.jdbc.Driver").newInstance();
aqui parece estar el error.
      String url =
"jdbc:mysql://mysql.webcindario.com";
      String login = "user";
      String password = "password";
      Connection conn =
DriverManager.getConnection(url,login,password);  
      if (conn != null)
      {
        JOptionPane.showMessageDialog(null,
"conexion", "alert", JOptionPane.ERROR_MESSAGE);
        conn.close();
      } 
    }
    catch(SQLException sql)
    {
      sql.printStackTrace();
    }
    catch(ClassNotFoundException cnfe)
    {
      cnfe.printStackTrace();
    }
    catch (Exception ex) {
      ex.printStackTrace();
    }

Please help me
