** JRendezvous
This is an implemenation of Rendezvous in Java. It currently
supports service discovery and service registration.
** Requirements
JRendezvous has been tested only on Windows using the JDK 1.3.1
and JDK 1.4.0. It has also been tried on Mac OS/10 using JDK1.3.1.
** Running JRendezvous from the Command Line
GUI browser:
java -jar jrendezvous.jar -browse
TTY browser for a particular service type:
java -jar jrendezvous.jar -bs _http._tcp local.
Register a service:
java -jar jrendezvous.jar -rs foobar _http._tcp local. 1234 index.html
To print debugging output specify -d as the first argument.
** Sample Code for Service Registration
import com.strangeberry.rendezvous.*;
Rendezvous rendezvous = new Rendezvous();
rendezvous.registerService(
new ServiceInfo("_http._tcp.local.", "foo._http._tcp.local.", 1234, "index.html")
);
** Sample code for Serivice Discovery
import com.strangeberry.rendezvous.*;
static class SampleListener implements ServiceListener
{
public void addService(Rendezvous rendezvous, String type, String name)
{
System.out.println("ADD: " + rendezvous.getServiceInfo(type, name));
}
public void removeService(Rendezvous rendezvous, String type, String name)
{
System.out.println("REMOVE: " + name);
}
}
Rendezvous rendezvous = new Rendezvous();
rendezvous.addServiceListener("_http._tcp.local.", new SampleListener());
** Changes since 9-10-2002
- Rendezvous.SocketListener: check done flag to avoid exception on close.
- Main: no arguments lauches the browser. Now you can double click on
the jar file
- Switch from GPL to LGPL. Now you can use JRendezvous in your
products without having to put them in the public domain.
** Changes since 29-11-2002
- Handle unicast DNS queries. This is required to integrated with
legacy DNS clients. You can now advertize services that can be
launched from the Safari browser on the Mac.
- Make domain names case insensitive in all cases. Mixed case is
still allowed and preseved, but it is now ignored in queries.
** Changes since 20-01-2003
- Fixed a bug introduced in the 20-01-2003, the query handler
was responding with unicast reponses to multicast queries.
This turned out to work fine when JRendezvous is talking to
another JRendezvous, but it fails when talking to other
rendezvous implementations.
- Fixed case sensitivity issue when removing services. This caused
multiple calls to ServiceListener.removeService.
- Increased the TTL from 1 minute to 1 hour.
- Started proper version numbers. The next release will be 0.1.1.
