Looks interesting and potentially worthwhile. I'm surprised that it leaves
out XForms from the mix - any particular reason why?

Subject: [xsl] [Announce] XX Framework Version 1.1 - XSL
Centric Java Web Framework
Hello everyone,
I am the developer of the XX Framework, which is an XML/XSL
oriented MVC Java web development framework. I've publicized
the framework mainly on the Java boards so far, but I think
it is perhaps more relevant for XSL users.
Here is the standard release announcement. I invite everyone
to take a look at the framework at
http://www.xxframework.org/ and to provide feedback.
Thanks

XX Framework Version 1.1
Infoblazer LLC. is pleased to release the XX Framework under
the LGPL open source license. Version 1.1 is available for
immediate download.
The XX framework is a configurable, XML/XSL-centric
implementation of the MVC development paradigm.
The primary goal of the XX Framework is to handle typical
application CRUD (create, retrieve, update, delete) with
little or no Java programming. Instead of telling the
application how to retrieve and how to display the data, we
configure what to retrieve (through XML) and what to display
(through XSLT).
This approach generally leads to a simpler and more elegant
solution that a purely procedural approach. Where the
applications needs more than simple CRUD, additional business
logic can be easily incorporated into the process. Some
additional features of the framework are configurable data
caching, thread pooling, and web service integration.
Some benefits of the framework are:
Extremely simple to use
Built around open web standards, including J2EE, XHTML, XML,
XSL, CSS Uses XSL and CSS as the application's View layer,
allowing total separation of presentation from back end
concerns. Page-focused/HTML templating approaches rarely
achieve this separation Configurable data caching for optimal
performance Automated data persistence (CRUD). 80% of a
typical web app can be built with no Java code Uses a
?Portal-based? approach to page design, allowing easy
compartmentalization of functionality Integration with web
services Reuse common classes and operations for pre-built
functionality Enabled caching and thread pooling for greatly
increased performance
The framework promotes a use case oriented development
approach. In this approach, use cases are defined for each
task the user will perform. In general, each use case will be
implemented by a single logical servlet, as defined in the
J2EE Specification. The logical servlet may be implemented by
one or more implementation classes each implemented a
distinct portion of that use case and providing a portion of
the resultant display.
The developer simply needs to write implementation of for
these classes. Configuration files determine which
implementation classes are called based on user click events.
The most common implementation approach has each class return
an XML result, yielding a set of XML documents for each use
case.. XSL transformation is then applied to the XML results,
each transform providing a portion of the desired display. A
single JSP page is then used to display the final product.
The framework then builds upon this foundational approach to
provide automation of typical application tasks, such as add,
update, delete, select of records from a database. By
specifying a simple mapping from the HTML page on one end,
through the middle layers, and to the database on the other
end, a large subset of application functionality can be
achieved without the need to write any Java code. Instead, a
combination of XML configuration files, XSL transformation
templates, as well as open source tools, namely Hibernate and
Castor, are used.
The goal of the framework is to incorporate more and more
common programming tasks, in an open, configurable, and
generic manner. Furthermore, since much of the framework if
based on XML and XSL, automatic generation of complete
applications is achievable.
