At LSUG's first meetup of 2014 Gerald Loeffler gives a succinct explanation and critical comparison of the defining architectural principles and coding styles in Akka Actors and Java EE 7 Enterprise JavaBeans (in particular JMS MDBs and session beans with asynchronous business methods).
Although Akka has a Java binding and Java EE is, obviously, a Java standard, this comparison will focus on usage from - and code in - Scala.
