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.
Qpid 0.32 Client Rabbit MQ 3.5.7
Exchange onms Routing Key Simon
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> ... }
}
}
