SUMMARY: hostname in java is always returning fully qualfied?

I figured out the problem here.

Many suggested to check out the /etc/hosts and /etc/hostname.<inteface>

Both did not have the fully qualified names. As well as uname and hostname
command all returned the non fully qualfied name.

But when looking at our nsswitch.conf file, I noticed what the issue was.

It was looking up nisplus first, and then dns, then exit. Well, for some
reason... most all of our Sun machines are not in the nisplus hosts list.
Though pretty much every other machine in existance here is. I really don't
know why the previous admin had configured it like this. So it was getting
it from DNS. I just added the culprit boxes to the nisplus database and all
is fine.

---Original Question---
	Developers have been moaning about a few Solaris 2.8 boxes here for
some time and they finally have me convinced that it is a Solaris(not a
Java) issue.

Basically, in java code there is a way to return the hostname of the
machine. Well in this case, two of our Solaris machines are always returning
the fully qualified name of our machine, instead of just the hostname.

They've shown me how they have ran it on about 200 machines(Windows, Linux,
Solaris, IRIX, Tru64) but just two machines, two of my many Solaris machines
are returning the fully qualified name instead of just the hostname.

Meaning its returing '' instead of just 'theMachine'

Any one have a clue as to how these Solaris machines could be configured

If you want to run/compile the code, it is below. We are using Sun's SDK 1.4
and JRE 1.4 for running it.

<begin code>

class test
    public static void main(String args[])
            String hostname = InetAddress.getLocalHost().getHostName();
            System.out.println("HostName is: " + hostname);
        catch(Exception ex)
            System.out.println("Could Not Get hostname");
<end code>
