Body:
Maybe stating the obvious, but in the code examples "localhost" is literal while
"hostname" is symbolic.
Replace "hostname" by a valid hostname within your local domain. For instance, a
hostname of "james" should work within the local domain of "apache.org" just as well
as the fully qualified name "james.apache.org".

Here is an overview of the issue:
---------------------------------------------------------------------
Key: JAMES-302
Summary: Functionality of org.apache.james.dnsserver.DNSServer.getByName(String)
is not symetric to java.net.InetAddress.getByName(String)
Type: Bug
Status: Unassigned
Priority: Critical
Project: James
Components:
DNSServer
Versions:
2.2.0
Assignee:
Reporter: Steve Brewin
Created: Tue, 6 Jul 2004 2:43 PM
Updated: Tue, 6 Jul 2004 2:59 PM
Environment: Tested on WIN2000, JDK 1.4.1_01-b01
Description:
org.apache.james.dnsserver.DNSServer.getByName(String) does not always return the same
result as java.net.InetAddress.getByName(address). Sometimes an exception is thrown
when the standard implementation does not.
When passed a fully qualified domain name the results are the same. When passed a
hostname or the special name 'localhost', a java.net.UnknownHostException is thrown by
org.apache.james.dnsserver.DNSServer while java.net.InetAddress resolves the addresses
correctly.
This is a critical issue as in v2.2.0 java.net.InetAddress.getByName() has pretty
thoroughly been replaced by org.apache.james.dnsserver.DNSServer.getByName(), but in
the noted circumstances it doesn't perform the same. Dependent code breaks.
Here are the contrasting examples...
// FAILS
String address = "localhost";
java.net.InetAddress inetAddress =
org.apache.james.dnsserver.DNSServer.getByName(address);
return inetAddress;
// FAILS
String address = "hostname";
java.net.InetAddress inetAddress =
org.apache.james.dnsserver.DNSServer.getByName(address);
return inetAddress;
// SUCCEEDS
String address = "localhost";
java.net.InetAddress inetAddress = java.net.InetAddress.getByName(address);
return inetAddress;
// SUCCEEDS
String address = "hostname";
java.net.InetAddress inetAddress = java.net.InetAddress.getByName(address);
return inetAddress;
