Apache Velocity-找不到资源异常

Question

我需要生成一些自动邮件，因此我想使用Velocity。我已将所有Velar Jars复制到lib文件夹，并创建了hello.vm模板，并将其放置在WEB-INF / templates文件夹中。是我得到的例外，

我尝试了所有其他使用classloader / webapps加载资源的方法，但错误仍然相同。我使用的是tomcat 7.27的netbeans7.2.x。欣赏是否有人可以为此建议。

下面是我的速度属性文件，

resource.loader = file
file.resource.loader.class = org.apache.velocity.runtime.resource.loader.FileResourceLoader
file.resource.loader.path = C:\Users\kiran\Desktop\Netbeans Projects\ourstory\web\WEB-INF\templates
file.resource.loader.cache = true
file.resource.loader.modificationCheckInterval = 2
runtime.log=/WEB-INF/logs/velocity.log 
runtime.log.logsystem.class=org.apache.velocity.runtime.log.Log4JLogSystem
runtime.log.logsystem.log4j.pattern=%d - %m%n
runtime.log.logsystem.log4j.file.size=10000
runtime.log.logsystem.log4j.file.backups=1

下面是我正在使用的servlet

import java.util.Properties;
import javax.servlet.http.*;
import org.apache.velocity.Template;
import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.VelocityEngine;
import org.apache.velocity.context.Context;
import org.apache.velocity.tools.view.VelocityViewServlet;

public class test extends VelocityViewServlet {
    private String htmlTemplate = "hello.vm";

    VelocityContext context = new VelocityContext();

    @Override
    public Template handleRequest(HttpServletRequest request,
            HttpServletResponse response,
            Context context) {
   //    Properties props = new Properties();
    //    props.setProperty("resource.loader", "class");
    //    props.setProperty("class.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
    //    props.setProperty("webapp.resource.loader.path", "/WEB-INF/templates/");

        VelocityEngine engine = new VelocityEngine();


        engine.init();

        Template template = null;

        try {
            context.put("name", "Velocity Test");           
                    template = engine.getTemplate(htmlTemplate);
           } catch (Exception e) {
             e.printStackTrace();
            System.err.println("Exception caught: " + e.getMessage());
        }
        return template;
    }
}

其简单的servlet，但由于某种原因，我无法使其正常工作。
