Title Rexx Scripts Hosted and Evaluated/Executed by Java (javax.script)
Speaker Prof.Dr.Rony Flatscher
Abstract The latest version of BSF4ooRexx (a Rexx/Java bridge) implements a Rexx script engine according to the specifications implemented in the Java package "javax.script". This presentation explains the core concepts of "javax.script" and introduces the "Rexx script engine" implementation with features that should ease programming and debugging "Rexx scripts" for Rexx programmers. Working stand-alone nutshell examples will demonstrate the new features and will also depeict the available possibilities to interact with the Java supplied ScriptContext for running the Rexx scripts.

Title JavaFX for ooRexx - Creating Powerful Portable GUIs
Speaker Prof.Dr.Rony Flatscher
Abstract JavaFX is a modern, multi-platform GUI programming environment with an interactive WYSIWYG GUI builder named "SceneBuilder". The JavaFX classes can be employed by Rexx applications that have a need for simple as well as complex GUIs. This presentation explains the JavaFX concepts and how to take advantage of them from Rexx. Working stand-alone nutshell examples will demonstrate how easy it is from Rexx to exploit JavaFX. This infrastructure is so powerful that it becomes possible over time to replace the Windows-only ooDialog-applications with modern GUIs that in addition are platform independent and not only run on Windows, but unchanged under Linux and MacOSX as well!
