As I wrote sunday, I experimented with beanshell and it worked pretty well und faster than I anticipated. Nevertheless I heard about some other scripting frameworks (and their integration in java 1.6) which motivated me to investigate a bit more in this direction. Apparently Mozilla’s Rhino is a very powerful yet fast framework that provides javascript aka ECMAscript. Performance benchmarks by Pankaj Kumar in his article BeanShell, Rhino and Java — Performance Comparison show that my choice of beanshell as a scripting framework might not have been that best – performance wise. I’ll definately check out Rhino for use in my application.

Another interesting framework I came across when looking into scripting with java is the Apache Jakarta Bean Scripting Framework (BSF) which provides a framework to create JSP pages in different scripting languages. To achieve this it offers a uniform interface which wraps several scripting languages like javascript, python, tcl and many more.
