establishing connection to mssql2000

[mohan kannan]

I am trying to establish connection to mssql2000 on server through JSP
Server Tomcat
The code used in jsp is

//import required packages
<%@ page language="java" import="java.sql.*, java.io.*, java.util.*" %>
//urlformat one
 String url="jdbc:odbc:Dsnname;UID=username;PWD=password";
//url format two
//String url="jdbc:odbc:Dsnname";
 Connection con=null;;  
  try 
      {
   // Load Driver.
   Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
   out.println("JDBC Driver Loaded");
     
  }
  catch (Exception le) 
  {
   out.println( "Error Number.1 : Could not Load JdbcOdbcDriver."+le.getMessage());
   }
 
  try 
      {
   // Connect to database.
  //connect using url format one
   con= DriverManager.getConnection(url);
//connect using url format two
  // con= DriverManager.getConnection(url,"username","password");
   out.println("Connected to database");
   
  catch (SQLException cnfe) 
  {
  out.println( "Error Number. 2 : SQLException: Could not connect to dB\r\n");
  
  out.println( "Error Message is "+cnfe.getMessage() + "\r\n");
  
  out.println( "Error Code is  " +cnfe.getErrorCode());
  out.println( "Error State is  "+cnfe.getSQLState() + "\r\n");
}
catch (Exception e) 
 {
      out.println( "Error No. 3 : Exception: An unknown error occurred while connecting to DB."+e.getMessage());
        
 }

It's loading the driver and "JDBC Driver Loaded " message received
I have properly replaced dsnname, username and password in url string with the exact dsn details provided by
my system administrator.
But when trying to get connection the server output is
Hello loading and connecting to dB
JDBC Driver Loaded
Error Number. 2 : SQLException: Could not connect to dB
Error Message is [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
Error Code is 0
Error State is IM002
The above error received for the both url formats
The same code /jsp file when run on local machine (mssql7 and tomcat 4.0.1) with the same dsn name properly configured
(Here I used user name="sa" and password="") is able to establish connection to database.
System administrator says that the dsn is configured properly on the server.
Please indicate whether the problem is with the code or the dsn is not properly configured at the server
thanks

The correct way of using Class.forName is
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver:DSNName");
out.println("JDBC Driver Loaded");
Thanks

Not true, you are confusing class names and JDBC URLs.
Class.forName expects the "fully qualified name of the desired class" - adding the DNS to the end is not correct.
