I've implemented a Listenable/Listener trait that can be added to Actors. I'm wondering if it's possible to attach this style of trait to an actor without it having to explicitly call the listenerHandler method? Also I was expecting to find this functionality in the Akka library. Am I missing something or is there some reason that Akka ...
Hi, We're looking at using actors in our Scala code quite soon. We're also thinking of moving to Scala 2.8 in the next few weeks. We've been keeping an eye on Akka but it doesn't currently support 2.8 and plans for it have slipped from the 0.7 release to 0.8 We would like distributed, supervised actors. Is there an alternative to Akka?...
We have some code which needs to run faster. Its already profiled so we would like to make use of multiple threads. Usually I would setup an in memory queue, and have a number of threads taking jobs of the queue and calculating the results. For the shared data I would use a ConcurrentHashMap or similar. I don't really want to go down th...
I'm trying to find the 'right' actor implementation for my thesis. I realized there is a bunch of them and it's a bit confusing to pick one. Personally I'm especially interested in remote actors, but I guess a complete overview would be helpful to many others. This is a pretty general question, so feel free to answer just for the impleme...
Is there a design document for Scala 2.8 Actors, like it is for 2.7? Scala Actors: Unifying Thread-based and Event-based Programming Is there one for Akka? The "Scala Improvement Documents Library" doesn't mention Actors. ...
There are a huge amount of tasks. Each task is belong to a single group. The requirement is each group of tasks should executed serially just like executed in a single thread and the throughput should be maximized in a multi-core (or multi-cpu) environment. Note: there are also a huge amount of groups that is proportional to the number o...
I have a Scala application using Akka that receives REST requests, makes some operations against a database, and responds with some information to the client. As it is, my db operations take a long time and my REST-enabled actor is unable to respond to new requests in the meantime, even though I could run lots of operations concurrently ...
We're developing a server system in Scala + Akka for a game that will serve clients in Android, iPhone, and Second Life. There are parts of this server that need to be highly available, running on multiple machines. If one of those servers dies (of, say, hardware failure), the system needs to keep running. I think I want the clients t...
Is it possible to run AKKA on Java 1.5? I'm getting java.lang.UnsupportedClassVersionError: Bad version number in .class file for se.scalablesolutions.akka.actor.LocalActorRef. AKKA version is 0.9.1 There's noting said about the JVM version limitations at http://doc.akkasource.org/getting-started ...
Can an Akka anonymous actor have access to self? In my particular case I'm wondering if I can reply back to the sender with code similar to this (does not compile due to self not being found): val xmlLoader = Actor.init { println("xml loader started") } receive { case LoadResource(url) => { try { val xml = XM...
