Portofino is a web application framework written in Java and extensible using Groovy, distributed under the LGPL open source license. The framework can be used to create interactive database-driven web applications. The creation process includes automatic generation through a "wizard" tool, manual configuration through a web-based administration interface, and customization through scripting languages. The framework combines features that are typical of Content Management Systems and of Rapid application development tools. Portofino is mainly intended for Java developers of enterprise applications and of dynamic web sites. It can connect to an existing database and generate a working web application based on an automatic analysis of the database's structure.
