Embedded Brokers discovery
hello
how I can configure embedded broker with discovery without xml
configuration.
I want to take functionality of xml :
transportConnector uri="tcp://localhost:0"
discoveryUri="multicast://default"

You mean Rendezvous was Apple's name for their instatiation of ZeroConf, but
now its called Bonjour. I did get the jmdns.jar into the lib
subdirectory...though it obviously didn't ever get loaded, as the code has
been commented out.
But thanks.

Hi,
Try using the rendezvous protocol. I think the zeroconf protocol is now
known as the rendezvous protocol. You will have to add the jmdns jar on
your classpath since it's not included in the distro.

Jonas

Ok, so I noticed in the code everything has been commented out. I suppose
this is due to the LGPL on the jmDNS stuff. What is the plan? I know there
is multicast capability, but I want to register with mDNS. Am I seeing that
this isn't possible anymore?

Were you ever able to get this to work? I really need to get discovery
working but since AMQ leaves off the protocol and domain I can't use real
Bonjour or mdns libraries. Using java isn't an option since it has to be
perl.

Note that things appear straight away if you use the browser that
comes with jmDNS
java -jar lib/jmdns.jar -browse
then it appears.
I've just patch SVN HEAD to explicitly prepend a "_" to ensure that
the names look a bit nicer in rendezvous. I even tried hacking
RendevousDiscoveryAgent to use similar naming schemes to other
services but I couldn't get the Bonjour Browser to pick it up - no
idea what the magic is (maybe known services have to be configured
into it in the right way for it to recognise it?)

James (and everyone else),
Ok, I feel somewhat stupid now. What I'm really looking for is to have the
ActiveMQ broker show up in my Bonjour Browser window. Now to make that
happen I'm think I need to add some stuff to the "ActiveMQ-4." string to
make it end up more like "default._ActiveMQ-4._tcp.local." which would then
appear in the mdns browser. I've edited the RendevousDiscoveryAgent.java
code, but am still not seeing it. Looking a little closer at the code
there, I am thinking I somehow need to call the registerService method in
order for it to actually make it to the mDNS server. Any help here would be
greatly appreciated.
TIA,
Kit

No - the code is still there. Use rendezvous:foo
I've just committed a test case using it which seems to work.

Yes, this discovery method works. However, I want to use mDNS. Just to
finalize this...
Is there no more support for jmDNS? Will the code still exist, allowing for
the capability to compiled in? Or is the Apache relationship going to
dictate that it (the code) go away completely?

The code Jonas provided should work fine...
BrokerService broker = new BrokerService();
broker..setUseJmx(false);
broker.setPersistent(false);
TransportConnector connector = broker.addConnector(new
URI("tcp://localthost:61616"));
connector.setDiscoveryUri(new URI("multicast://default"));

In this case, you want to create a TCP server side transport and add a
discovery mechanism to it. Adding discovery to the front of a URI is
purely used on the client side.

Making a newbie assumption that to add zeroconf registration all I need to do
is add discovery to the front of the URI.
But. Here's the output I get:

Any ideas? What am I doing wrong? FWIW, I tried added the discovery option
to the example activemq.xml configuration and tried to start a broker with
the script and get the same thing...
TIA,
Kit

Hi,
If you have downloaded the source code of AMQ 4.x, you can find some test
cases that will be helpful:
trunk\activemq-core\src\test\java\org\apache\activemq\core\ (ie.
ActiveMQConnectionFactoryTest)
Below is a sample configuration of the Broker using java configuration :
BrokerService broker = new BrokerService();
broker..setUseJmx(false);
broker.setPersistent(false);
TransportConnector connector = broker.addConnector(new
URI("tcp://localthost:61616"));
connector.setDiscoveryUri(new URI("multicast://default"));
broker.start();
Regards,
Jonas
