Connet sql server 2008 to java with sqljdbc

Question

I'm trying to connect sql server 2008 with java and I tired to read from microsft documentation and other internet sites to do it and always get an mistake. I used sqljdb, sqljdb4, sqljdb4.1 and any
the most simple codec is:
 public static void main(String[] args) throws SQLException{
        try {
            String connectionUrl = "jdbc:sqlserver://localhost.\\SQLEXPRESS:1433;" +
            "databaseName=hackeadorazodb;user=hacker;password=;integratedSecurity=true";
            Connection con = DriverManager.getConnection(connectionUrl);
            if(con != null){
                System.out.println("exito");
        } catch (Exception e) {
            System.out.println("error: "+e.toString());

Hi hackeadorazo,
Could you please post the full error message?
From your description, it seems that you are connecting to a named SQL Server instance locally.
Firstly, please make sure the following things.
    1. SQL Server is running in SQL Server Configuration Manager (SSCM)
    2. TCP/IP is enabled in SSCM.
    3. SQL Server is listening on port 1433. Right-click "TCP/IP" in SSCM > SQL Server Network Configuration > Protocols for SQLEXPRESS, then choose "Properties" and click "IP Addresses" tab, you
can check the port from “IPAll/TCP Port”.
Secondly, if you use current Windows user account (Windows authentication) to log on SQL Server, the
connection URL should be as follows.
String connectionUrl = "jdbc:sqlserver://localhost\\SQLEXPRESS:1433;" + "databaseName=hackeadorazodb;integratedSecurity=true";
If you use a SQL Server account (SQL Server authentication) to
log on SQL Server. You need to specify username and password in the
connection URL as follows. In addition, please make sure that SQL Server is configured as “SQL Server and Windows Authentication Mode “in SQL Server Management Studio (SSMS) and the login ‘hacker’ exists in SQL Server Instance>Security>Login.
String connectionUrl = "jdbc:sqlserver://localhost\\SQLEXPRESS:1433;" + "databaseName=hackeadorazodb;user=hacker;password=<Password>";
