Hello scala people,

the more I read about Scala the more I like it.
I am working on a little web app project and I want convert it
to Scala from Java.

Now I am thinking about using Actors as services. I searched but
I do not realy find something about it.

Has someone experience with his? Or can someone give me some
hints?

I find the Akka project from Jonas, is it for such a scenario?
Schould I look to Erlang OTP to understand it better how to use Actors as
Service?

Hello greekmac,

yes, Akka would certainly fit this use-case.
Please have a look at the Akka documentation at http://wiki.github.com/jboner/akka
And be sure to check out the samples in the codebase, they're named: akka-sample-*

 

with best regards

This is what Akka is created to address.

Here is the doc explaining erlang-style supervisor hieranchies in Akka:
http://wiki.github.com/jboner/akka/reference-supervisor-hierarchies-faul...
Good starting point.

Here is remote actors (very efficient NIO based impl:
http://wiki.github.com/jboner/akka/reference-remoting-distributed-active...

If you have any questions there is a user list:

Hello,

I found that Blog post
http://suereth.blogspot.com/2008/08/adding-scala-actors-to-your-spring.html
adding-scala-actors-to-your-spring and I like the approach to have
a trait, that is my interface and gives me the API. I cant use this with
akka actors...?
I dont have a complete overview yet.

I look at the samples...I can configure the strategy how the actors should
be managed...
but how do the actors interact with each other...something is missing in my
head :)

with best regards

I might misunderstand but I think that you would like to have what
Akka's Active Objects provide; a regular Java API (through POJO or
Interface+POJO) wrapping an actor. These are as performant,
fault-tolerant and feature-complete as the regular Actors.

Read more here:
http://wiki.github.com/jboner/akka/reference-active-objects-java-api
Sample here: http://wiki.github.com/jboner/akka/examples

The piece that is missing is Spring integration but that would be
trivial to do. Join the akka-user mailing list and we can discuss what
you need there.
