Overview
The Data Info code is used to define the data provided by a web application, its grouping in a navigation tree and the linking between different web applications. All the data, grouping and linking information is stored in the glastgen database.
The code provides a set of classes to read/update the database and a set of beans to easily access this data in a JSP environment. The beans are added to each of the application's sessions via a filter that is meant to be added to the application. The filter also adds additional functionality for saving/loading information via xml files. Finally we provide a set of tag files containing forms to view/edit the data, grouping and linking information. These tag files can be easily embedded in web applications.
