What is Mocha?

Mocha is the original project name of the very popular scripting language generally known as Javascript and standardized as Ecmascript ECMA-262/ISO-16262. We use the term Mocha to refer to the usage of Ecmascript outside of the scope generally attributed to Javascript, integrating both client-side and server-side programming with other technologies such as XML and Java. It is an extremely rich, powerful and flexible programming language and has a large, highly developed syntax, a huge library of standard methods (functions) and built-in capabilities to create complex, object-oriented data structures and methods.

Mocha also is a port in Yemen, historically famous as the major source for "arabica" coffee beans. Due to its aromatic undertones of chocolate, the term Mocha also often describes a blend of coffee and chocolate when referring to a beverage or a flavor of ice cream :-)

What is OpenMocha?

OpenMocha is an Internet and Website application development framework for Mocha developers. OpenMocha is an open source project that integrates various Mocha related open source components around a core based on the Helma application server.

In the OpenMocha framework, solutions are defined by collections of Mocha Objects, which handle the various types of standard client-server requests. These collections are dynamically inherited from the hierarchical tree of parents for the requested page. The Mocha Objects are application segments containing scripts and/or skins, separating logic and design. Requests are processed by running through the appropriate collection of Mocha Objects for the requested URL hierarchy and executing them relative to the requested page.

The OpenMocha framework is made up of several related projects. Mochascript is an abstraction library extending both client-side and server-side Javascript environments. The Mocha Object Engine is the layer that implements the Mocha Objects and collections and defines the layer of the framework that is itself implemented in Javascript. The Helma Object Publisher serves as the application server for the Mocha Object Engine, providing an embedded XML database and automatic mapping of objects to relational databases such as MySQL, PostgreSQL or Oracle, integrating the Rhino Javascript Engine with the other Java components and providing the Mocha environment with access to Java packages. The Jetty Java HTTP Server provides Web, XML-RPC and AJP13 services, while the James Java Enterprise Mail Server provides SMTP, POP3 and NNTP services. The OpenMocha framework also intregrates the Lucene Search Engine for powerful Java-based text indexing.
