  • Method Details

    • getLocalHostName

      public static String getLocalHostName() throws UnknownHostException
      When using the InetAddress.getHostName() method in an environment where neither a proper DNS lookup nor an /etc/hosts entry exists for a given host, the following exception will be thrown:

      java.net.UnknownHostException: <hostname>: <hostname> at java.net.InetAddress.getLocalHost(InetAddress.java:1425) ...

      Instead of just throwing an UnknownHostException and giving up, this method grabs a suitable hostname from the exception and prevents the exception from being thrown. If a suitable hostname cannot be acquired from the exception, only then is the UnknownHostException thrown.

      Returns:
      the hostname
      Throws:
      UnknownHostException - is thrown if hostname could not be resolved

      Instead of just throwing an UnknownHostException and giving up, this method grabs a suitable hostname from the exception and prevents the exception from being thrown. If a suitable hostname cannot be acquired from the exception, then null is returned

      Returns:
      the hostname, or null if not possible to resolve
