Unable to connect to server inside swing app

[DN Debed]

Hi, I would like to ask for your help with my problem.

The code below works fine if I run the class itself in netbeans.

But in my swing application, calling the createTestFolder method using a command button gives this exception.

com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host  has failed. java.net.SocketException: Malformed reply from SOCKS server

This is my class used to connect to the sql server.

  ((
package utility;
import java.sql.Connection;
import java.sql.DriverManager;
import java.util.logging.Level;
import java.util.logging.Logger;

public class Test {
    public static void main(String[] args) {
        try {
            new Test().createTestFolder();
        } catch (Exception ex) {
            Logger.getLogger(Test.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
    public void createTestFolder() throws Exception {
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            String connectionUrl = "jdbc:sqlserver://172.16.221.11\\testserver:4343;database=MYDB;username=mysa;password=mypassword;";
            System.out.println("getting conection...");
            Connection con = DriverManager.getConnection(connectionUrl);
            System.out.println("success");
        }catch(Exception ex) {
            ex.printStackTrace();
        }        
    }
}

thanks!

Google com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host has failed., seems like a problem with the remote db server.
