Connessione a db Oracle

[Ironmax]

Qui di seguito è quello che ho creato come classe ed l'errore che mi genera:

import java.sql.*;
 
public class TestDBOracle {
 
  public static void main(String[] args)
      throws ClassNotFoundException, SQLException
  {
    Class.forName("oracle.jdbc.driver.OracleDriver");
        String URL = "jdbc:oracle:thin:@//localhost:8080/apex";
        String USER = "max1234";
        String PASS = "1234";
        Connection conn = DriverManager.getConnection(URL, USER, PASS);
    conn.setAutoCommit(false);
    Statement stmt = conn.createStatement();
    ResultSet rset =
         stmt.executeQuery("select * from persona");
    while (rset.next()) {
         System.out.println (rset.getString(1));
    }
    stmt.close();
    System.out.println ("Ok.");
  }
}

Nella console:

Exception in thread "main" java.sql.SQLRecoverableException: IO Error: Got minus one from a read call

        String URL = "jdbc:oracle:thin:@//localhost:8080/apex";

Il url non mi "quadra" molto .... localhost:8080 è più qualcosa riferito ad un web server (es. un Tomcat in locale sulla 8080 o l'application server di Oracle).
