GlueX Web Applications Framework

GlueX framework is a XML/XSLT-centric library simplifying building of Java web applications using standard servlet containers supporting Sun's Java(TM) Servlet Specification version 2.2 or later. The main principle of GlueX is clear separation between application logic, state and presentation. Application state is expressed in XML and then transformed to presentation (HTML or other markup language) with XSL transformation. Command pattern is used to cope with complexity of business logic which is common for all large applications.

GlueX framework provides application developers with advantages such as:

Pure MVC (Model-View-Controller) compliance

Clear separation between application logic and user presentation

Multiple presentations (designs) with stylesheets inheritance

Internationalization

Flexible XML configuration of application workflow

Built-in request parameters validation

Automatic generation of error messages resource file with support for internationalization

Automatic generation of action documentation

Strong ACL-based security model

Developer creates set of "action" classes, XSL stylesheets, and ties them with set of XML configuration files. This greatly simplifies building of modern web applications with complex workflows.
