Getting the remote path of an actor in 2.0-RC1

[smr]

Hi!

I'm trying to get the actor remote path but the method actor.path()
returns the local path.

My akka version is 2.0-RC1 and my configuration are:

akka {
actor {
provider = "akka.remote.RemoteActorRefProvider"
}

remote {
transport = "akka.remote.netty.NettyRemoteTransport"
netty {
hostname = "127.0.0.1"
port = 2552
}
}
}

The ActorSystem creation...

Config config = ConfigFactory.load().getConfig(configName);
ActorSystem system = ActorSystem.create(systemName, config);

And the actor creation...

ActorRef actor = system.actorOf(new Props(actorclass), name);
String path = actor.path().toString();


This configuration works with 2.0-M2 and 2.0-M3 (with the correct
transport class, of course), i.e. actor.path() returns the actor
remote path.

How can I get the remote path of an actor in 2.0-RC1?

Thanks!

Sonia

Hi Sonia,

What problem are you trying to solve by using the external address?

Cheers,

Hi Viktor,

I want to have a client that can invoke remote actors dynamically.
Therefore, I need to know the remote paths when the actors are
created.

Best regards,

Sonia

Hi Sonia,

Just give the client the ActorRef?

Hi,

Yes, I want to give the client the ActorRef returned by the actorFor
but for that, I need the remote path of the actor.

Thanks,

Sonia

Your code looked like this:

ActorRef actor = system.actorOf(new Props(actorclass), name);
String path = actor.path().toString();

I assume your remote client is also an actor:

remoteClient.tell("this is your new buddy", actor)

Or, if this is not the case, I think you need to provide some more code.

Hi Viktor,

I think that I haven't explained so good.

I don't create actors remotelly, I create the actors in the server
side and then I tell the client the remote path of them.

When I create an actor, in the server side, with remote support in 2.0-
M2 and 2.0-M4, the actor path is an remote path. But, when I create an
actor in version 2.0-RC1, the actor path is a local path. I'm using
the method actor.path() for get the actor path.

How I must recover the remote path of server side actor?

Thanks you,

Sonia

Hi Sonia,

while it is possible to obtain the remote address, you should not need it unless under very specific circumstances, most notably when serializing ActorRef yourself.

One thing you left out in the description of your scenario is how client and server communicate. If they just use Akka remoting, then the only thing you need is to send the ActorRef directly, no paths needed.

Regards,

Roland

Hi Roland,

we really need the remote path of the actor, cause our problem is relative to serialization.

What is the way to retrieve it?

system needs to be coerced to ExtendedActorSystem, which is why it's
done in an Extension.
