Hello all ,

URL u=new URL("telnet://route-server.exodus.net");

This line is generating :

java.net.MalformedURLException: unknown protocol: telnet

And i encounter similar problems with other URLs that begin with "news://"

These are URLs extracted from ODP , so i dont understand why such exceptions arise..
