 Template Engines > Velocity > Quite Reference

Quite Reference 

Apache Velocity is a free, simple and powerful template engine written in 100% pure Java. This requires the libraries velocity-1.7.jar, oro-2.0.8.jar, commons-lang-2.4.jar, commons-collections-3.2.1.jar, commons-logging-1.1.jar, log4j-1.2.12.jar to be in classpath. The following example shows using Quite Reference notation ($!) in Velocity. It prints empty space in place of missing variables.

    ve.setProperty("classpath.resource.loader.class", ClasspathResourceLoader.class.getName());
        Template template = ve.getTemplate("quite.vm");
        
        /**

        VelocityContext context = new VelocityContext();

        /**

         */
        StringWriter swOut = new StringWriter();
        template.merge(context, swOut);
        
        System.out.println(swOut);
  }
}
