Helma is an open source web application framework for fast and efficient scripting and serving of your websites and Internet applications.
It is written in Java and employs Javascript for its server-side scripting environment, removing the need for compilation cycles and reducing development costs while giving you instant access to leverage the whole wealth of Java libraries out there.
Helma pioneered the simple and codeless mapping of application objects to database tables, which has only recently come into vogue with other web frameworks. In addition, an embedded object-oriented database performs automatic data persistence of unmapped objects.
Helma has proven itself to be stable and fast, capable of serving high traffic sites with hundreds of thousands of dynamic pages per day. The Austrian Broadcasting Corporation, popular weblog hosting sites such as antville.org, twoday.net, and blogger.de, among many others, have successfully been deploying Helma for several years.

- This release adds subskins, macro pipes/filters, an update to Rhino 1.6, E4X support, the ability to define getters/setters, and many improvements to the host objects in the JavaScript environment.
