Server initiated remote actor microkernel deployment

[Ross McDonald]

Hi Guys.

I have some server initiated remote actors which have been in production for a while. They run happily in 'sbt console' or run as a library in various servlet containers. I would now like to test deploying to the microkernel for the sake of portability. I have tried a few options but keep getting the same error, wondering what I am doing wrong.

Sample remote actor:

class DummySimpleActorService extends ... {

override def init = {
RemoteNode.start("localhost", 9999)
RemoteNode.register("dummy:service", self)
}
}

Sample deployment:

...
...
class Boot {
val supervisor = Supervisor(
SupervisorConfig(
RestartStrategy(AllForOne, 3, 1000, List(classOf[Exception])),
Supervise(
actorOf[DummySimpleActorService],
LifeCycle(Permanent),
RemoteAddress("localhost", 9999))
:: Nil))

//val actorService = actorOf[DummySimpleActorService].start

/*class Boot {
val factory = SupervisorFactory(
SupervisorConfig(
RestartStrategy(OneForOne, 3, 100,List(classOf[Exception])),
Supervise(
actorOf[DummySimpleActorService],
LifeCycle(Permanent))
:: Nil))
factory.newInstance.start
}*/
}

I keep getting :

java.lang.ClassNotFoundException: dummy:service

This smells like a nasty bug/regression. I'll take a look at it ASAP.
Is it master?

Hi Jonas.

Yes, master, updated this morning.

Hi Ross,

could you send a full startup-log (you can send it privately if you want)

I think there could be an initialization-ordering issue at fault here.

Cheers,

Are you getting this without sending the actor any messages? Looks
like it receives a message and then dies. Can you post the full code?

Hi.

I get this when I send the actor its first message. I am just going to bash together a quick dummy project, I will try to attach it on the list or email it once I am done.

Hi,

Jonas, somehow it thinks "dummy:service" is a Fully Qualified Class Name?

I need to head out to grab something to eat,
if you need my assistance when I get back I'm available.

Yes. That is it. It mixes ID with class name. Shouldn't be too hard to find.

Take it. I'm up to my nose in doc hell.
