Requirements

Apache Maven 2.+ Java 1.6+ Active _MQ 5.8+

Compile Source

$ mvn clean compile

Active MQ Console

http://localhost:8161/admin/ admin / admin

Point-to-point messaging. The Producer creates 2 queues and sends messages to a Master/Slave AMQ Broker using the failover protocol. Messages are processed from a Consumer in an asynchronous manner.

$ cd async-queues-failover
$ mvn clean compile
$ mvn exec:java -Pproducer
$ mvn exec:java -Pconsumer

SSL transport. Producer and Consumer send/receive messages over a SSL tunnel. In order to successfully connect to the AMQ broker via SSL, the keystore, the keystore password, and the truststore are provided using JSSE.

$ cd ssl-transport
$ mvn clean install
$ mvn exec:java -Pproducer
$ mvn exec:java -Pconsumer

Simple project for asynchronous requests (like Ex. 01), but based on Spring-JMS. Running the application, it starts Spring context and the producer; then Spring automatically instantiates the message listeners (for consumers).

$ cd spring-basic
$ mvn exec:java

Messaging example using the Active MQ REST APIs.

• Consumer

The example uses the DefaultMessageListenerContainer of spring framework for the JMS Consumer. The Consumer is created through the Spring beans context which automatically instantiates the message listener when you run the example.

• Producer

The Producer consists of a series of regular HTTP POST which send messages to a queue named "Coda01" as JSON format. The messages are published on the ActiveMQ Server using the RESTful API implementation. A numbers of messages can be produced by sending a POST request to the server with Basic Authentication. The ActiveMQ RESTful API is available by default at:

http://your_server_amq:8161/api/message

### For example, you can produce by sending a POST request to the server, like:
> curl -u admin:admin -H "Content-Type: application/json" -d '{"myMessage":"this is the message"}' http://localhost:8161/api/message/Coda01?type=queue

Finally , messages are processed from the Consumer in asynchronous manner.

• Run example

$ cd rest-producer
$ mvn clean compile
$ mvn exec:java -Dexec.args="[AMQ_HOST] [NUMBER_OF_MESSAGES]"

For example, the following sends 10 messages to the localhost AMQ Server

$ mvn exec:java -Dexec.args="localhost 10"
