Local resolution

[Norman M. <no...@ap...>]

Hi all,

we using dnsjava in our project ( james.apache.org), and it works great.
But sometimes we need to resolv "localhost". This is not possible with
dnsjava, because it not take care about /etc/hosts etc. So we have to
resolv such lookups with InetAddress usage.

Is it planned to resolv this kind of stuff ? Maybe be able to enable it
via a "switch" ?

Thx
Norman

I don't know exactly what you mean by a "switch".  As far as I know, 
there's no standard or nonstandard way to figure out what the OS uses 
other than DNS to do hostname resolution, and no way to ask the OS to 
attempt alternative methods of hostname resolution without also doing DNS 
queries.

If what you're asking for is simply the ability to parse /etc/hosts, that 
would be possible, but wouldn't be useful on systems with have other ways 
of configuring static DNS data, and I'm pretty sure Windows systems don't 
have /etc/hosts files.

Yes parsing the file whould be enough here. For sure there are other
places for other OS'es. So maybe we on our own to write some wrapper to
do the stuff.

I haven't had much time to work on dnsjava recently, so if you want 
something soon, you'd probably want to write it yourself.  I'd be happy to 
accept patches, of course.
