[Grails] JMS Plugin - Message not displaying

[venu v gopal v]

Hi,
I have created a sample grails application by installing jms and activemq plugins with the 1.2-M3 version
created a controller and a service class with the following code...

class OnNotificationService
{
	boolean transactional = false
	static expose = ['jms']
	static destination = "queue.notification"
        def onMessage = 
       {
           println 'GOT MESSAGE: $it'
       } 
}

and the controller code is as follows

class NotificationController {
	def index = {
		def message = "Hi, this is a Hello World with JMS & ActiveMQ, " + new Date()
		sendJMSMessage("queue.notification", message)
		render message
	}
}

Am not able to get the display in console, but am getting in browser when we click the controller.
please suggest me on this.......

A couple of house keeping things; please UseCodeTags when displaying code so that it keeps the formatting and is easier to read. Also, you might consider better subjects. The subject 'Grails' is very vague. I've adjusted both.

Do you mean you don't get anything on the console or just the message you sent is missing? because this...

println 'GOT MESSAGE: $it' 

...is wrong.

Hi Bolinger,

Thanks for your quick response,
so what i need to write/replace to debug my println statement.
I am getting the message output in the browser, but the message what i have written in service.groovy that should be shown
on the console but its not showing. IT Should display GOT MESSAGE.
can you please suggest me on this.

Why are you using Grails 1.2-M3 ? Try the latest release (1.2.2) and see if you are still having issues.

Hi Bolinger,

Still am having the same issue. The messages which i printed in the service am not able to get in the console and i tried it
with the latest grails-1.2.2 version. can you suggest me why this happening.
And also i have used the code on the following lik.

Hi,

Two things are wrong:

First of all "expose" misses an 's'. It should be "exposes".

Second the method "onMessage" should be defined taking a parameter. All in all this should do the trick:

  static exposes = ["jms"]

  def onMessage(msg) {
    println "GOT $msg"
    return null
  }

Furthermore you can use a named queue by specifying the destination like:

  static destination = "queue.notification"

Happy hacking!
