Re: [akka-user] Remote Actor not starting up[Need Help]

[√iktor Ҡlang]

Hi Raju,

Akka doesn't magically create Actorsystems on other machines.

Please read the docs and FAQ

Cheers,

Hello everyone;

I am getting timed out exception while trying to access Remote actors from local machine.

My application.conf file for remote actors is

RemoteSys {
    akka {
        actor {
            provider = "akka.remote.RemoteActorRefProvider"
        }
        remote {
            transport = "akka.remote.netty.NettyRemoteTransport"
            netty {
                hostname = "125.153.76.235"
                port = 2552
            }
        }
    }
}

after deploying an application in remote machine i ran bootable class using akka scripts,while doing so i dont get any error but it doesnt show that remoteactor has been started.
Please help me in figuring out why actor system is not started in remote machine.

Thanks;
raju

Hello Raju,

Compare your code with this example to figure out what you are missing/doing incorrectly:

"No configuration setting found for key 'RemoteSys'" means that there's no configuration setting for that key available.

I would start digging in that end.

The timeout exception you get indicates that the node you're trying to call is not available.

Are you sure that it is up and running? Are you using the right address when you try to call it?

I have not read Akka Essentials so I cannot comment on the examples in that book.

However, I know that our docs are up to date and that the examples provided run as intended.

Should you run into more problems I suggest that you either contact the author of the book or try with the provided examples.

Thanks

//Henrik

Hello,

I had the same problem, and it got fixed renaming resource folder to resources :)
