I have a small application with RemoteActors, and I want to make a jar file from it. When I try to execute it it gets this exception:

I have included scala-library.jar in my jar file, and it is in the classpath. Otherwise java would stop at finding the class ScalaObject.
The problem was a version mismatch between the Scala plugin on Eclipse and the installed Scala version. actors/Combinators.scala appeared in 2.8, and the Eclipse plugin was 2.8 however I included 2.7.7 scala-library.jar
