View engines

Thymeleaf support

AcrossWebModule automatically activates Thymeleaf support for server-side templating. Thymeleaf is a powerful templating language that allows its templates to be embedded inside the JAR files (something that is more cumbersome with regular JSP).

AcrossWebModule itself - as well as many other modules - use Thymeleaf extensively and add additional features for it (like custom dialects).

When Thymeleaf support is enabled, the Thymeleaf Java 8 Time dialect is also included.

The Thymeleaf templates embedded in modules are expected to be located in the views/th/moduleResourceKey resources folder. The supported file extension is *.html. See the chapter on static resource conventions for an example project layout.

JSP support

Support for regular JSP/JSTL can be enabled by setting the property acrossWebModule.views.jsp.enabled to true.

Combining JSP and Thymeleaf

If both JSP and Thymeleaf support are enabled, you can easily use both view types at the same time. The AcrossWebModule also provides a JSP tag that can be used to import Thymeleaf templates or fragments in a JSP rendering pipeline. The same model (request attributes) should be available in the Thymeleaf template as in the calling JSP.

<%@ taglib prefix="across" uri="" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="" xml:lang="en" lang="en">
	<title>JSP including a Thymeleaf template</title>
	<across:thymeleaf template="th/mymodule/thymeleaf-from-jsp-include" />
	<div class="child">
		<across:thymeleaf template="th/mymodule/thymeleaf-from-jsp-include :: fragment" />

Using other templating engines

It is still possible to use additional templating engines. You can do so by extending the AcrossWebModule configuration and registering custom Spring ViewResolver beans.
