Is there any way to create JSF applications using scripting languages and its own persistence engines? The answer is: Yes! After some hours trying to integrate JSF + JRuby + ActiveRecord I finally could get a very simple application working, this application contains only one page where the user can add some costumer data, we have jsp as view, spring as IoC container and integration point with JRuby, ActiveRecord-JDBC as ORM.
The page has a managedbean defined as Ruby class, each Ruby bean must implement a Java interface to allow integration with Java/Spring, when the bean is requested by Spring a Java proxy class is instantiated based on its Java interface and then all Ruby code can be consumed properly.
If you wanna try by yourself you must create a webapplication and add the jars described on my previous post (except groovy-1.5.4.jar) plus these jars below on WEB/lib folder:
