The JHTML page is compiled first into a .java file and then into a Java .class file. The application server runs the code in the .class file as a servlet whose sole function is to emit a stream of standard HTTP and HTML data back to the HTTP server and on back to the client software (the web browser, usually) that originally requested the ...

Also the exact Java API (and hence the class) of the values can be hidden in FreeMarker using a technique called object wrapping. For example, "messages" seems to be a list or array of JavaBeans that have "from" and "body" properties, but it might as well be something very different, and the template is not affected (as long as a proper object ...
Apache Velocity first released in April 2001, is a Java-based template engine that provides a template language to reference objects defined in Java code. It aims to ensure clean separation between the presentation tier and business tiers in a Web application (the model–view–controller design pattern).
A Java class file is a file (with the .class filename extension) containing Java bytecode that can be executed on the Java Virtual Machine (JVM).A Java class file is usually produced by a Java compiler from Java programming language source files (.java files) containing Java classes (alternatively, other JVM languages can also be used to create class files).
Each server-side page component holds a nested hierarchy of stateful components, where each component's model is, in the end, a POJO (Plain Old Java Object) Wicket aims for simplicity. There are no configuration files to learn in Wicket. Wicket is a simple class library with a consistent approach to component structure.
The value for the scope defines the duration for which the bean is available for the rest of the java application to use. The scope can be one of the following four values: [ 9 ] The page scope implies that the bean is located in the implicitly defined PageContext object, and is only available for the current page.
The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an HTML or XML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects.
