提一个DWR的问题

Question

做了一个DWR的测试
dwr.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN" "http://www.getahead.ltd.uk/dwr/dwr10.dtd">
<dwr>
  <allow>
    <create creator="new" javascript="JDate">
      <param name="class" value="java.util.Date"/>
    </create>

web.xml
<servlet>
  <servlet-name>dwr-invoker</servlet-name>
  <display-name>DWR Servlet</display-name>
  <servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
  <init-param>
     <param-name>debug</param-name>

  </init-param>
</servlet><servlet-mapping>
  <servlet-name>dwr-invoker</servlet-name>

当我访问http://lcalhost/app/dwr时出现了以下错误
javax.servlet.ServletException: Error allocating a servlet instance
...............................
java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet
两个错误
求大家指导

你的dwr.jar 不在目录里吧!?  在eclipse里测试和在tomcat容器里测试不一样的``
