Helma is a server-side Javascript environment and web application framework for fast and efficient scripting and serving of your websites and Internet applications.

Helma 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. 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.

Helma 1.7.0 Released

The Helma 1.7.0 release contains some bug fixes and major improvements, such as programmable HopObject collections and prototype mappings, Apache Commons Daemon support, a profiler for measuring function runtime and invocation frequency, and skin/macro introspection, to mention just a few. It also contains an updated version of Rhino and is the first Helma release that has Javascript 1.7 features enabled by default. The Helma 1.7.0 Changelog has the nitty gritty details. Better get it now, before there is an even better one. Really, it's that good!
