Connection refused: connect Error in Java + Hibernate

I am trying to do this tutorial and when I got to the hibernate part, I get this errors:

Here is the hibernate.cfg.xml part of accessing the database:

<!--Database connection settings-->
<property name="connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
<property name="connection.url">jdbc:jtds:sqlserver://localhost:1433;databaseName=MyTut1db</property>
<property name="connection.username">sop1</property>
<property name="connection.password">myPW1</property>
<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>

The user sop1 was created in MS SQL Server 2012 Express edition as:

CREATE LOGIN sop1
    WITH PASSWORD = 'myPW1';
USE MyTut1db;
GO
CREATE USER sop1 FOR LOGIN sop1;
GO 

The database properties are in the figure below:

I have inabled the TCP-IP from MS SQL Server Configuration Manager (TCP Port is 1433), but the problem still persists.

I have also closed the antivirus for a while.

I am asking for some help: What else can it be? How do I verify the user? How do I know that localhost:1433 is the right server?
