POAccessing Grails ActiveMQ from Remote Machine

copied!<p>I am new to JMS stuff.. I read the JMS and ActiveMQ plugins documentation but still not clear with it . </p> <p>I am trying to build a system where a Grail app hosted on machine A with ActiveMQ embedded in it should be capable of sending messages. And another Grails app hosted on Machine B with just the JMS plugin should be able to receive messages and respond to it.</p> <p>After reading the documentation I created a grails App on machine A where controller sends the message to service on Machine A and it displays the message on Console. Now I am trying to implement a service with similar behavior on Machine B.</p> <p>After configuration on Machine B , my resource.groovy looks like this:</p> <pre><code> 1 2 import org.apache.activemq.ActiveMQConnectionFactory 3 import org.springframework.jms.connection.SingleConnectionFactory 4 beans = { 5 6 jmsConnectionFactory(SingleConnectionFactory) { 7 targetConnectionFactory = { ActiveMQConnectionFactory cf -> 8 brokerURL = 'vm://machineA.mydomain.com' 9 } 10 } 11 } </code></pre> <p>And the service on Machine A and B look like this:</p> <pre><code>1 package replicationsiteapp 2 3 import grails.plugin.jms.* 4 5 class OnNotificationService { 6 7 8 boolean transactional = false 9 static exposes = ['jms'] 10 static destination = "topic.notify" 11 boolean isTopic = true 12 13 14 @Subscriber(topic = "topic.notify") 15 def onTopicMessage(it){ 16 17 println " YOU GOT MESSAGE FROM : $it" 18 } 19 24 } 25 </code></pre> <p>Controller on Machine A:</p> <pre><code> package hello class NotificationController { def index() { def message = "Hi, this is a Hello World with JMS & ActiveMQ, " + new Date() sendTopicJMSMessage("topic.notify",message) render message } } </code></pre> <p>Machine A: Grails 2.1 on Unix with plugins installed (ActiveMQ and JMS)</p> <p>Machine B: Grails 2.1 on Unix with plugins installed (JMS)</p> <p>Current Issue:</p> <p>When message is sent from Controller on Machine A Service on Machine A displays message in console but Machine B doesnot</p> <p>Expected: Machine B should also receive the messages</p>
