Integration of Httl to Struts2 in eclipse

What is Httl?

HTTL (hyper-text template Language) is a high-performance, open-source Java template engine for Dynamic HTML page output that can replace JSP pages with instructions similar to velocity.

HTTL Official website:

http://httl.github.io/zh/

The background presented here is based on STRUTS2 and Httl development of a simple example of a Java EE: where the background logic code with STRUTS2, the foreground dynamic display page with Httl (JS library arbitrary selection).

Anyway

Integrating HTTL into your project requires:

1, now to the HTTL official website Download two jar package:

(1) Httl core package Httl-1.0.11.jar, version can be downloaded according to their own needs.

(2) Struts Integration Pack Http-struts-1.0.11.jar.

You need to explain here. Do not think that only download a Http-struts-1.0.11.jar integration into the project, in fact, the content of the Http-struts-1.0.11.jar is very simple, contains only one struts result type =httl's template explains the engine and a struts-plugin.xml. In fact, the package only defines and implements a STRUTS2 result type, which does not contain the HTTL core package.

2. Place the Httl attribute file httl.properties in the Web-inf directory.

The contents of my properties file are as follows:

import.packages+=domaintemplate.directory=message.basename=/web-inf/messagesinput.encoding= Utf-8output.encoding=utf-8

What needs to be described here is the need to configure the Import.packages property, which is interpreted as "Domain Model Package Import", which is the package where the various Java beans are located.

Report:

1. Eclipse Integration Struts2: see article http://blog.csdn.net/tterminator/article/details/45423003

2. When integrating HTTL related packages into the project, a binary package is required instead of the source code package, which is the jar package containing the *.class, not the *. Java's jar package.

3. When the Httl core package is not introduced, no exception will occur to start the Tomcat deployment file, but exception java.lang.ClassNotFoundException:httl.web.WebEngine may occur on access:
