Apache Velocity 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). Velocity is an open source software project hosted by the Apache Software Foundation. It is released under the Apache License. == Uses == Some common types of applications that use Velocity are: * Web applications: Web designers create HTML pages with placeholders for dynamic information. The page is processed with ''VelocityViewServlet'' or any of a number of frameworks which support Velocity. * Source code generation: Velocity can be used to generate Java source code, SQL, or PostScript, based on templates. A number of open source and commercial development software packages use Velocity in this manner. * Automatic emails: Many applications generate automatic emails for account signup, password reminders, or automatically sent reports. Using Velocity, the email template can be stored in a text file, rather than directly embedded in Java code. * XML transformation: Velocity provides an Ant task, called Anakia, which reads an XML file and makes it available to a Velocity template. A common application is to convert documentation stored in a generic "xdoc" format into a styled HTML document. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Apache Velocity」の詳細全文を読む スポンサード リンク
