    Simple Flexible Template Solution in Java

    J-Tree is a lightweight, modular, extendible and recursive open source Java component framework with a template core. A J-Tree template is "executable" by itself. J-Tree contains some standardized actions and a data container. These actions are called when a comment tag is found. The action is controlled by the attributes within. Actions can have any purpose. Templating is just an action by itself. The template controls loading of data and storing to a file by itself. So it runs indempentently from a java development environment just from a shell call (exectutable) The website offers several examples how it works. These are: - Simple examples demonstrating looping within a page or create several pages based on the data of a simple Excelsheet. - Website/document creation by the web-site itself - Creating sql, model, model classes from a model sheet and load data with it - Extend actions with a java code line counter
