Using QPID Java Client i can only get messages delivered through the exchange to the bound queue using the following expanded syntax of AMQAnyDestination

Destination queue = new AMQAnyDestination( new AMQShortString("onms2"), 
                                               new AMQShortString("direct"),
                                               new AMQShortString("Simon"),
                                               true,        
                                               true,        
                                               new AMQShortString(""),
                                               false,       
                                               bindvars);

If i attempt to use the different form which just specifies the address as follows it doesnt work:-

Destination queue = new AMQAnyDestination("onms2/Simon");

The message hits RabbitMQ ok but is not delivered.

I have been using the qpid examples and modifying the ListSender example as below

package org.apache.qpid.example;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.jms.Connection;
import javax.jms.Destination;
import javax.jms.Message;
import javax.jms.MessageProducer;
import javax.jms.Session;

import org.apache.qpid.client.AMQAnyDestination;
import org.apache.qpid.client.AMQConnection;

import org.apache.qpid.framing.AMQShortString;
import org.apache.qpid.jms.ListMessage;


public class ListSender {

public static void main(String[] args) throws Exception
{
    Connection connection =
        new AMQConnection("amqp://simon:simon@localhost/test?brokerlist='tcp://localhost:5672'");
                                               AMQShortString a1 = new AMQShortString("");
                                               AMQShortString a2 = new AMQShortString("");
    AMQShortString[] bindvars = new AMQShortString[]{a1,a2};
    boolean is_durable = true;
    /*
    Destination queue = new AMQAnyDestination( new AMQShortString("onms2"), 
                                               new AMQShortString("direct"),
                                               new AMQShortString("Simon"),
                                               true,        
                                               true,        
                                               new AMQShortString(""),
                                               false,       
                                               bindvars);
    */

    Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
    Destination queue = new AMQAnyDestination("onms2/Simon");
    //Destination queue = new AMQAnyDestination("amqp:OpenNMSExchange/Taylor; {create: always}");
    //Destination queue = new AMQAnyDestination("OpenNMSExchange; {create: always}");
    MessageProducer producer = session.createProducer(queue);

ListMessage m = ((org.apache.qpid.jms.Session)session).createListMessage();
    m.setIntProperty("Id", 987654321);
    m.setStringProperty("name", "WidgetSimon");
    m.setDoubleProperty("price", 0.99);

    List<String> colors = new ArrayList<String>();
    colors.add("red");
    colors.add("green");
    colors.add("white");
    m.add(colors);

    Map<String,Double> dimensions = new HashMap<String,Double>();
    dimensions.put("length",10.2);
    dimensions.put("width",5.1);
    dimensions.put("depth",2.0);
    m.add(dimensions);

    List<List<Integer>> parts = new ArrayList<List<Integer>>();
    parts.add(Arrays.asList(new Integer[] {1,2,5}));
    parts.add(Arrays.asList(new Integer[] {8,2,5}));
   m.add(parts);

    Map<String,Object> specs = new HashMap<String,Object>();
    specs.put("colours", colors);
    specs.put("dimensions", dimensions);
    specs.put("parts", parts);
    m.add(specs);

    producer.send((Message)m);
    System.out.println("Sent: " + m);
    connection.close();
}

}

When it works using the expanded format of AMQAnyDestination the debug logs looks like this:-

163  [main] INFO  org.apache.qpid.client.AMQConnection  - Connection 1 now connected from /127.0.0.1:43298 to localhost/127.0.0.1:5672

When it fails using the shorter syntax the debug log looks like this:-

Ideally i need the shorter syntax to work as this is what is used by another application I am using which is posting messages using AMQP.

I suspect there is something incorrect with the syntax i am using to define the address but i cant see what it is.

I have tried:-

amqp:onms2/Simon ADDR:onms2/Simon

I have confirmed the rabbit config is correct by testing using both a standalone java client using qpid and also using both perl (using net_amqp) and python (using pika). So i dont think its that.

Any gudiance appreciated.

EDIT:- Found some extra configuration parameters on the QPID website i had missed When i configure the address as follows it works! onms3/Simon; {'create':'always','node':{'type':'topic'} } Detail

<name> [ / <subject> ] ; {
create: always | sender | receiver | never,
delete: always | sender | receiver | never,
assert: always | sender | receiver | never,
mode: browse | consume,
node: {
type: queue | topic,
durable: True | False,
x-declare: { ... <declare-overrides> ... },
x-bindings: [<binding_1>, ... <binding_n>]
},
link: {
name: <link-name>,
durable: True | False,
reliability: unreliable | at-most-once | at-least-once | exactly-once,
x-declare: { ... <declare-overrides> ... },
x-bindings: [<binding_1>, ... <binding_n>],
x-subscribe: { ... <subscribe-overrides> ... }
}
}
