SQL server weird connection problem-Pls help

Question

I m using SQL server 2005 express. My default logon mode setting is set to-SQL server authentication and I can logon to using SQL server management studio express always. I enabled TCP/IP from SQL server configuration manager. The sqljdbc.jar (JDBC driver) is set correctly in classpath and 1433 port is allowed in windows firewall. YET, I can�t connect to sql server using the following code-
import java.sql.*; public class testconn { Statement stmt; Connection con = null;       String driver = "jdbc:sqlserver://"; String server = "localhost:1433;"; String db = "database=IDLC-Customer;"; String user = "userName=Tanvir;"; String pwd = "password=abcd;"; String connectName = driver + server + db + user + pwd;    testconn() { try {       Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");       con= DriverManager.getConnection(connectName);       stmt=con.createStatement();       if(!con.isClosed())         System.out.println("Successfully connected to " +           "SQL server using TCP/IP...");     } catch(Exception e) {       System.err.println("Exception: " + e);    }     finally {    try {         if(con != null)           con.close();         } catch(SQLException e) {}    }        }   public static void main(String args[]) {       testconn tc=new testconn();   } }
My host name is- Tanvir. So, in management studio express the server name is shown- TANVIR\SQLEXPRESS
When I run the code it says-The TCP/IP connection to the host has failed.
Java.net.connectException:Connection Refused: Connect
One more thing, though 1433 port is allowed in windows firewall, I can�t connect to that port using telnet (e.g. telnet <server_host> 1433).I even disabled firewall and tried but in vain. PLEASE help me brother.

Then you, seemingly, have not configured your SQL server properly, or you have not "activated" that configuration.
(don't ask because I don't know how, or even if, you do it that way with SQL Server).
But, not being able to connect with telnet, means that nothing is listening on that port. What does the netstat command tell you?Brother,as u know that sql server use the default port 1433 even if i don't mention it.And I tried disabling my firewall and antivirus but yet I cant connect.I searched the ports using "Advanced port scanner" but the port 1433 is neither in its open ports list nor in closed port list. WHat can I do now.The port 1433 is by default used by sql server.So even if I dont mention it or set it, it should work.Isn't it? I m getting out of my mind, pls help .
