Errors upon trying to use ActiveMQ

[Hussein Baghdadi]

Hey,
I'm trying to use ActiveMQ in our application.
I installed JMS plugin and ActiveMQ is running.
activemq-all.jar is under lib dir.
Here is resources.groovy:

import org.apache.activemq.ActiveMQConnectionFactory 

beans = { 

  connectionFactory(ActiveMQConnectionFactory) { 
    brokerURL = "tcp://localhost:61616" 
  } 

} 

I defined this service:

class MessageBrokerService { 

  def messageService //not used in this service 

  def sendMessage() { 
    log.debug "Sending message to Queue" 
    sendQueueJMSMessage("bulkQ", "Harness ActiveMQ") 
  } 

} 

And the unit test:

class MessageBrokerServiceTests extends GrailsUnitTestCase { 

  def messageBrokerService 

  protected void setUp() { 
    super.setUp() 
  } 

  protected void tearDown() { 
    super.tearDown() 
  } 

  void testSendToMq() { 
    messageBrokerService.sendMessage() 
  } 
  
} 

But upon running the test, I got:
Cannot invoke method sendMessage() on null object
java.lang.NullPointerException: Cannot invoke method sendMessage() on null object
It looks that the service isn't get injected, right?
What is going wrong?
Platform:
JDK 6
Grails 1.2.1
ActiveMQ 5.3
JMS plugin 0.5

If it is a true Unit Test (not integration test) then you're not going to get services and jms stuff wired in. You'll either need to mock it or write an integration test.

Indeed, thanks for help Gregg.
But what is really annoying to me:
1. Lack of good documentations.
In resources.groovy, jmsConnectionFactory should be defined but the http://www.grails.org/JMS+Plugin defined connectionFactory which isn't working.
2. Grails is about 70% available.
So slow to run, slow to run tests, slow to get plugins list.
Rails and Django really beat Grails hard in this aspect.
Any way, thanks for help and time.

One more thing :p
I defined this consumer:

class MessageListenerService {

  static expose = ["jms"]

  static destination = "bulkQ"

  static listenerCount = 5

  def messageService

  def onMessage(messageInfo) {
    log.debug "Got incoming message for ${messageInfo.userFirstName}"
    log.debug "Now sending via MessageService"
    println "Now sending via MessageService"
    //Sending ....
  }

}

But I got this exception:
javax.jms.InvalidDestinationException: Cannot determine response destination: Request message does not contain reply-to destination, and no default response destination set

Questions about plugins are often times better asked on the grails mailing list. That's where all the plugin devs typically hang out. I'd post this question to them. I personally can't help with this. I've only used the JMS plugin one time and as a test. Sorry.

I doubt anyone is forcing you to use grails. If you like Rails and django better, well, use them.

[Hussein Baghdadi]

No, no one is forcing me to use Grails.
I just wishing if Grails team overcome these issues (IMO).
Thanks again.

I contacted the plugin author and he helped me.

Thanks for posting a link to the solution.
