Answer 1

s = (DataSource)ctx.lookup("jdbc/MyDataSource");
               Connection con = ds.getConnection("sa","manshu");This is a JNDI lookup for the data source, a Java EE notion. What Java EE app server are you sending the JNDI request to?

both are correct..SQL Server 2005 knows nothing about Java EE. It does not have any notion of what a JNDI lookup is.
is it possible to connect this way ??No.
plz answer... i am learning..Use the DriverManager to connect.
You don't need a Windows DSN, but you do need a JDBC driver. You can get it either from Microsoft or jTDS, an open source JDBC driver. You download JAR files and add them to your CLASSPATH. Be sure you do that properly. Don't depend on a system environment variable. Use the -classpath option of java.exe when you run.
