ManyDesigns Portofino 4
Portofino is a web application framework written in Java and extensible using Groovy, distributed under the LGPL open source license. It is developed by ManyDesigns, based in Genoa, Italy (http://www.manydesigns.com).
The framework can be used to create good looking database-driven web applications. The creation process can include automatic generation through a "wizard" tool that analyses the structure of a relational database, manual configuration through a web-based administration interface, and customization through Groovy code. The result is a fully functional application with a responsive web user interface, REST APIs, users and permissions, an email subsystem and much more, which is easy to incrementally extend and customize, both graphically and in functionality (e.g., adding new buttons to existing pages).
Portofino is based on popular and proven open source libraries such as Hibernate, Groovy, Apache Shiro, the Stripes web framework, Twitter Bootstrap, Jersey JAX-RS.
The home of Portofino is http://portofino.manydesigns.com. There you can find the documentation, pointers to community resources (forums, wiki, issue tracker), commercial support.
The official compiled distribution is hosted on SourceForge: http://sourceforge.net/projects/portofino It requires no installation, just unzip it. It is a bundle of Apache Tomcat, Portofino and JDBC drivers for popular open source databases.
