[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.
CppCMS is a C++ Web development framework (not CMS). It differs from most of other Web development frameworks like Python Django, Java Servlets, or C++ Wt because it is designed and tuned to handle extremely high loads, and it is aimed at development of Web sites rather then "GUI-like" Web applications.
