Velocity is a Java-based template engine. It allows web page designers to refer to methods defined in Java code. Web designers can work in parallel with Java programmers to develop MVC-mode Web sites, which means that Web page designers can focus only on creating well-designed sites, and programmers can focus only on writing top-tier code. Velocity separates Java code from Web pages, making Web sites more m
JS Struts Recipes's co-author George Franciscus takes you step-by-step through integrating the Velocity template engine into the Struts application. The result is a fast, flexible JSP replacement with all the conveniences you can expect from Struts. Java? Server Page (JSP) technology is so pervasive that people forget that there are other options when creating Web pages. But recently, some developers have turned to the template engine to gain fle
