** JmDNS

This is an implemenation of multi-cast DNS in Java. It currently
supports service discovery and service registration. It is fully
interoperable with Apple's Rendezvous. 



** Requirements

jmdns has been tested using the JDK 1.3.1 and JDK 1.4.0
on the following platforms:

Windows 9x, XP, 2000
Linux   RedHat 7.3-9.0, Mandrake
Mac OSX



** Running jmdns from the Command Line

GUI browser:

  java -jar lib/jmdns.jar -browse

TTY browser for a particular service type:

  java -jar lib/jmdns.jar -bs _http._tcp local.

Register a service:

  java -jar lib/jmdns.jar -rs foobar _http._tcp local. 1234 path=index.html

List service types:

  java -jar lib/jmdns.jar -bt
  
To print debugging output specify -d as the first argument.  



** Sample Code for Service Registration

    import javax.jmdns.*;

    JmDNS jmdns = new JmDNS();
    jmdns.registerService(
    	new ServiceInfo("_http._tcp.local.", "foo._http._tcp.local.", 1234, 0, 0, "path=index.html")
    );


** Sample code for Serivice Discovery

    import javax.jmdns.*;

    static class SampleListener implements ServiceListener
    {
	public void addService(JmDNS jmdns, String type, String name)
	{
	    System.out.println("ADD: " + jmdns.getServiceInfo(type, name));
	}
	public void removeService(JmDNS jmdns, String type, String name)
	{
	    System.out.println("REMOVE: " + name);
	}
	public void resolveService(JmDNS jmdns, String type, String name, ServiceInfo info)
	{
	    System.out.println("RESOLVED: " + info);
	}
    }

    JmDNS jmdns = new JmDNS();
    jmdns.addServiceListener("_http._tcp.local.", new SampleListener());


** Changes since October 2003

- Renamed package com.strangeberry.rendezvous to javax.jmdns
- fixed unicast queries
- fixed property handling
- use the hostname instead of the service name is address resolution
- Added Apache License.
