Java - UnknownHostException [duplicate]

Question

dedicated Linux server throws UnknownHostException.

InetAddress addr;
    try {
        addr = InetAddress.getLocalHost();
    } catch (UnknownHostException e) {
        throw new InstantiationError("cannot find hub ip");
    }

Have you had a look at these google.co.uk/search?q=getLocalHost+UnknownHostException as I believe the are multiple possible causes. — Peter Lawrey

Another option I found was this(which I like as I don't have to repeat the hostname in both files now)...

java getLocalHost() UnknownHostException /etc/hosts file differs linux api?
