MsSQL forbindelse i Java

Hej

Jeg skal have lavet en forbindelse til MsSQL i Java. Jeg bruger følgende stykke kode til at connecte til min db. problemet er at jeg får en fejl:

java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]Login failed for user 'user'. Reason: Not associated with a trusted SQL Server connection.

Er der nogen der kan hjælpe mig??

import java.*;
public class Connect{
    private java.sql.Connection con = null;
    private String url = "jdbc:microsoft:sqlserver://";
    private String serverName= "localhost";
    private String portNumber = "1433";
    private String databaseName= "databasename";
    private String userName = "user";
    private String password = "pass";
     
    public Connect(){}
   
    private String getConnectionUrl(){
          return url+serverName+":"+portNumber+";databaseName="+databaseName+";";
    }
   
    private java.sql.Connection getConnection(){
          try{
              Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
              con = java.sql.DriverManager.getConnection(getConnectionUrl(),userName,password);
              if(con!=null) System.out.println("Connection Successful!");
          }catch(Exception e){
              e.printStackTrace();
              System.out.println("Error Trace in getConnection() : " + e.getMessage());
        }
          return con;
      }
}
