Freemarker is used for presentation, Jetty is used as the default web container, and there is a basic integration with Hibernate (but other persistence mechanisms can be used). The framework requires two layers over the top of \"business logic\" classes: a Java web layer where certain simple method and class naming conventions are used to facilitate easy mapping of data to and from HTML, and Freemarker page templates. A small number of Freemarker tags are defined to enable references to Macaw-based objects within the page templates. |
