spring-amqp and spring-integration version incompatibility

hi gary:
using spring-amqp 1.1.1.RELEASE it seems i have to change the version of spring-rabbit to 1.0.0.RELEASE

<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-amqp</artifactId>
<version>1.1.1.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-rabbit</artifactId>

<version>1.0.0.RELEASE</version>
</dependency>

the problem is this forms the core to a spring-integration webapp for which i need spring-rabbit:1.1.0.RELEASE which has support for dead-letter-exchange.

even when i upgrade spring-rabbit:1.1.1.RELEASE i get the same error as with 1.1.0.RELEASE of spring-rabbit.

the error is :
Caused by: org.springframework.beans.factory.NoSuchBeanDefini tionException: No bean named 'replies' is defined
at org.springframework.beans.factory.support.DefaultL istableBeanFactory.getBeanDefinition(DefaultListab leBeanFactory.java:527)


what would you recommend we do?

thanks and regards,

I am not sure what you mean by "it seems i have to change the version of spring-rabbit to 1.0.0.RELEASE".

You should simply use spring-rabbit 1.1.1.RELEASE and it will bring in spring-amqp 1.1.1.RELEASE as a transitive dependency.

What is "replies".

sorry, not to explain the situation, this was posted on lists.rabbitmq from an older post.
http://rabbitmq.1065348.n5.nabble.co...s-td20687.html

here's the spring-context file :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:rabbit="http://www.springframework.org/schema/rabbit"
xsi:schemaLocation="http://www.springframework.org/schema/rabbit http://www.springframework.org/schem...rabbit-1.1.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">


<!-- sets up the exchange -->
<rabbit:connection-factory id="rabbitConnection" />
<rabbit:admin connection-factory="rabbitConnection" auto-startup="true"/>

<rabbit:template reply-queue="replies" id="amqpTemplate" connection-factory="rabbitConnection"
exchange="s2-amqp.direct" routing-key="submitEchoPayload" queue="amqp_echoPayload">
<rabbit:reply-listener/>
</rabbit:template>


</beans>

so "replies" is the name of reply-queue for template entry. the problem is spring-amqp-1.1.1.RELEASE doesn't work well with spring-integration for dead-letter-exchanges.

here's the dependency tree for the project:

the same config works with the following pom entry ( using spring-amqp 1.1.0.RELEASE )
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-rabbit</artifactId>
<version>1.1.1.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-amqp</artifactId>
<version>1.1.0.RELEASE</version>
</dependency>

The attribute reply-queue is not a queue name, it needs to be a reference to a queue...

Code:

---

<rabbit:queue name="replies" />

Thanks much Gary!
that clears up a lot of things..however, how come the strange combination of spring-rabbit-1.0.0.RELEASE and spring-amqp-1.1.1.RELEASE works with reply-queues="replies" w/o complaining?
[w/o going through the code, i had assumed, you take a queue name - totally wrong, but works with the strange combination above]

FYI (for all else using spring-integration along w/ spring-amqp)
use spring-integration-amqp 2.2.0.M2 which will pull in spring-rabbit-1.1.1.RELEASE => spring-amqp-1.1.1.RELEASE.

Well, I'd need to know what you mean by "works".

I very much doubt it "works" as you suspect, because there was no support in spring-rabbit-1.0.0.RELEASE for a fixed reply queue on the RabitTemplate; that feature was added in 1.1.0

well, it seems to gary.
the code is really simple :
src/main/java/com/bear/EchoClient.java :
//removing imports for brevity..
public class EchoClient
{
private static Logger logger = LoggerFactory.getLogger(EchoClient.class);
private static final String PAYLOAD = "Hello world";
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("classpath:rabbitCo nfiguration.xml");
AmqpTemplate amqpTemplate = (AmqpTemplate)context.getBean("amqpTemplate");
logger.info("[Sent:"+PAYLOAD+"]");
String reply = (String)amqpTemplate.convertSendAndReceive(PAYLOAD );
logger.info("[Received:"+reply+"]");
System.exit(0);
}
}

src/main/resources/rabbitConfiguration.xml:
<!-- removed xml prologs and ns includes for brevity -->
<!-- sets up the exchange -->
<rabbit:connection-factory id="rabbitConnection" />
<rabbit:admin connection-factory="rabbitConnection" auto-startup="true"/>

<rabbit:template reply-queue="replies" id="amqpTemplate" connection-factory="rabbitConnection"
exchange="s2-amqp.direct" routing-key="submitEchoPayload" queue="amqp_echoPayload">
<rabbit:reply-listener/>
</rabbit:template>


</beans>


and finally pom.xml :
......

<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-amqp</artifactId>
<version>1.1.1.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-rabbit</artifactId>
<version>1.0.0.RELEASE</version>
</dependency>
.....

can send you a jar of source if required.
