I would like to use Akka actors in Java.
I downloaded the akka-1.0.zip and added akka-actor-1.0.jar to my \"Build Path\" in Eclipse.
In your akka-1.0.zip file there is scala-library.jar. Try adding it to the build path.
Also, there is a lib_managed directory inside the zip, which contains further library files. Possibly aslo some of them will be needed.
To avoid this kind of situations you should try maven. There is a Akka repository: http://scalablesolutions.se/akka/repository/se/scalablesolutions/akka/
