Hi,

I used the following code to create a InetAddress from lilnklocal
address ( returned by getifaddrs function).
   try{
        InetAddress add =
InetAddress.getByName("fe80::216:3eff:fe38:74e8%eth0");
     }
     catch(UnknownHostException uhe){
        System.out.println("Caught unknownhost exception ");
        System.out.println("Message: "+uhe.getMessage());
        uhe.printStackTrace();
    }


But it fails with the following message.

java.net.UnknownHostException: no scope_id found
        at java.net.Inet6Address.deriveNumericScope(Inet6Address.java:
358)
        at java.net.Inet6Address.initif(Inet6Address.java:321)
        at java.net.Inet6Address.initstr(Inet6Address.java:306)
        at java.net.Inet6Address.<init>(Inet6Address.java:232)
        at java.net.InetAddress.getAllByName(InetAddress.java:1062)
        at java.net.InetAddress.getAllByName(InetAddress.java:1009)
        at java.net.InetAddress.getByName(InetAddress.java:959)

What could be the possible reasons for it ?  Is it specific to JDK
version ?
