This just in from Jay. I think he's probably right that it's 2000 only
-- I had thought I had the problem on NT too, but I can't now remember
the chronology of seeing the problem on a particular machine and
replacing NT with 2000 on the same machine -- it may be that I'd already
upgraded it to 2k when I saw the problem.

I've got problems sending to the newsgroup, but I thought I'd reply
personally, in case it helps.

Are you definitely having problems with both 2000 and NT, or maybe just
2000?  I found a bug with InetAddress.getLocalHost() on WIN2000, and
maybe it's related to the way Tomcat works internally.  The code below
shows it best:

    try {
        localHost = InetAddress.getLocalHost();
        //
        //  Because of a bug on WIN 2000, getLocalHost() may
        //  return 0.0.0.0, for this machine.  Clear localHost
        //  flag so we can try again below.
        //
        if (localHost.getHostAddress().equals("0.0.0.0")) {
            localHost = null;
        }
    }
    catch (UnknownHostException e) {
    }
    //
    //  If we haven't succeeded yet, try the loopback address.
    //
    if (localHost == null) {
        try {
            localHost = InetAddress.getByName("127.0.0.1");
        }
        catch (UnknownHostException e2){
            throw (new Exception("Unable to resolve local host name."));

        }
    }

Subject: 'localhost' v '127.0.0.1' in workers.properties

Has anyone else found that NT/2000 can't resolve 'localhost' in a line
like

worker.ajp13.host=localhost

in conf/workers.properties?

I had the problem when I was developing the domino connector and someone

else has just reported the same problem to me. On the machine where I
had the problem

  nslookup localhost

was fine, and the problem persisted whether or not there was a localhost

entry in hosts. I haven't tried other hostnames there.
