Port error tcp ip in java connection with sql server


Well, more than problem in the code I think it will be installation but, well, if you can help me, I would greatly appreciate it: It all starts when I have to install sql server 2014 express edition on a client's computer, all right, you can even create database, also open port 1433 in the firewall, both input and output, but when executing the following connection code to make a query in the database which is the following (java):

    package accesoDatos;

import java.sql.*;

public class conexion {
    public static Connection Conectar() throws Exception{
        try {

            Connection cn=DriverManager.getConnection("jdbc:sqlserver://ISPL\ISPL:1433;"
                    + "databaseName=TecnoTrony","sa","sql");

            Connection cn=DriverManager.getConnection("jdbc:sqlserver://ORLANDO-PC:1433;"
                    + "databaseName=TecnoTrony","sa","sql");

            return cn;

        }catch (Exception e) {

            throw e;



When debugging, I returned the typical error that the tcp ip ports are closed or can not connect for any other reason, I stress that the jdk and java version are the same, the .net something that I could not fix I guess that will be the minimum required for sql server 2014, if not otherwise had not installed this same, the only thing I could have forgotten might be to define the port tcp ip in the services manager of sql server, assuming no, that is What may generate this error?
