Freemarker Templates

In the course Freemarker Templates participants learn to use the Apache FreeMarker template engine to generate text output such as HTML pages or emails based on templates.

FreeMarker Template Language

The templates use the FreeMarker Template Language (FTL) and are used for the View in the Model View Controller pattern (MVC). The templates only contain display logic that serves to display dynamically prepared data that is retrieved from the backend by a programming language, often Java.

Web Application Architecture

The course starts with a discussion of the architecture of Web Applications using Java as an example, of which the FreeMarker templates form the front-end. The basic principles of the HTTP Protocol are discussed, such as Requests, Responses and Sessions.

FreeMarker Syntax

After that FreeMarker values, types, directives, interpolations, control flow and the use of variables in templates are discussed. Namespaces, autoescaping and various output formats are also on the course program.

FreeMarker Data Model

Next attention is paid to the FreeMarker Data Model, where Java objects become visible in the template as a tree structure of variables and where adapters determine how they end up in the template.

Template Configuration

Finally various settings for template configuration are discussed and error handling, template loading and the implications of the use of multiple threads are treated.

Audience Training Freemarker Templates

The course Freemarker Templates is intended for developers and designers who want to use Freemarker in the User Interface of Java Web Applications.

Prerequisites Course Freemarker Templates
