Re: Finding the HostName

Vijay Kumar gave this program invocation and its output:

javac ipadd.java
$
java ipadd
java.net.UnknownHostException: empty string
      java/lang/Exception.<init>(Ljava/lang/String;)V+1 (Exception.java:45)

java/net/InetAddress.getAllByName(Ljava/lang/String;)[Ljava/net/InetAdd
ress;+11 (InetAddress.java:413)
      java/net/InetAddress.getLocalHost()Ljava/net/InetAddress;+36
(InetAddre
ss.java:509)
      ipadd.main([Ljava/lang/String;)V+1 (ipadd.java:9)
$


My response:

This is probably some sort of problem in your TCP/IP setup
and not a Java problem per se.  Check your name resolution
entries (GO CFGTCP and it is probably in menu option 10 or 12, forget
which).
