Apache Rivet is a system for creating dynamic Web content via a programming language integrated with Apache Web Server. It is designed to be fast, powerful and extensible, consume few system resources, be easy to learn, and to provide the user with a platform that can also be used for other programming tasks outside the web (GUIs, system administration tasks, text processing, database manipulation, XML, etc.). It is similar to PHP, except that it uses Tcl, and provides both HTML/Tcl pages as well as pure Tcl pages to aid the programmer in separating logic and presentation when necessary.
Roundhouse is a modular J2EE application platform that allows applications to combine Struts modules, JSR-168 portlets, and Web services into a single application. It is intended to take the drudgery out of new J2EE application development by providing existing user and security architecture, navigation, and logging although it can be used standalone with no additional development. It ships with forum and blog modules along with several handy portlets which essentially make it a a portal based blog and forums application. The architecture is Struts-based and includes a Struts-based JSR-168 Portlet container. Developers extend Roundhouse by creating new standalone modules which can be independently developed without mucking around in the Roundhouse codebase and merged with Roundhouse and any number of other modules at build time. Modules can be created, packaged as MARF files, and redistributed.
FreeSB is a (service oriented) alternative to hub-and-spoke messaging, enabling new and legacy systems to plug in to the bus and communicate with other systems on it, thus providing loosely-coupled application integration. FreeSB is currently implemented in Java but ESB clients should be implementable in other languages (Python, .Net, etc.).
Oness is an ERP, CRM, SRM, and inventory management solution primarily supporting the textile commerce. It is based on J2EE technologies such as Spring, Hibernate, Struts, XDoclet, AspectJ, and Maven with a JSP-based Web interface. It is completely modular and thoroughly documented.
SPindent (Server Page Indenter) is a JSP/PHP structural validator and indenter. It performs structural compatibility check of inner HTML generated from "parallel" branches of process flow statements such as if/else. It allows for those HTML branches to have different entry and exit HTML stack points, as far as the branches are compatible. This allows for verification and proper indentation of handy workarounds, as well as rusty pyramids. It is based on MixedCC (Mixed Compiler Compiler).
MixedCC (Mixed Compiler Compiler) is a parser-generator framework for multi-layer templates. It also works as a detachable stack machine engine. LL(1) BNF grammars of respective layers are specified in JavaCC-like syntax. The lexer is either JavaCC-generated or user-written. Tokens can represent stack-machine transition commands.
Tapestry is a rich, component-based object model for developing dynamic, robust, highly interactive Web applications. Applications are constructed in terms of Java objects, methods and properties, instead of URLs and query parameters. It builds and interprets all URLs, dispatching directly to application-specific "listener" methods. It includes complete source code, documentation, tutorials and a complete example J2EE application.
Pylets is a fast, lightweight, aspect-oriented Web framework built on mod_python and Apache. It uses Apache logs (and more Apache configuration in the future.) It can use Python objects, packages, and modules, or whatever the programmer wants. Pylets are also template-agnostic. With the debug switches off, and caching turned on, Pylets are less than 2x slower than serving static pages. The package comes with ORMit, a lightweight DB-API 2.0 connector-compatible object relational mapper.
