XEO (eXtensible Enterprise Objects) is an agile development framework designed for creating Web applications built around Object Oriented concepts and Model Driven Development with Java. You model business entities (including their attributes and behavior) as XEO Models which are then processed by the framework's "Builder". This produces the application's supporting structures such as database tables (to persist data) and Java classes (providing object-relational mapping and behavior). Development is supported by an Eclipse plugin called XEOStudio.
The Dextop application framework allows you to create Rich Internet Applications based on .NET/Mono and Sencha Ext JS. It has proven to be useful for online business applications.

[fleXive] CMS is a Java EE content management system based on JavaServer Faces 1.2. It combines the power of JSF XHTML templating with that of the Java EE 5 content repository, [fleXive]. Some highlights include dynamic JSF templating (Facelets), easy integration of custom logic with EJB or JSF beans, a modular structure, Maven support, generic data structures, and WebDAV and CMIS support. It incorporates all core [fleXive] features like security, versioning, multilinguism, and scripting.
ShortPHP was designed to be the shortest, smallest, quickest Web framework possible. The code is currently less than 4KB in size and is just under 100 lines. In some ways, you could say that it follows the MVC (Model-View-Controller) paradigm, but since it has no database-related code (it is completely file-based) it's more of a VC (View-Controller) system. It's up to the developer to use whatever tools are deemed fit. ShortPHP is fully E_STRICT compliant.
