    最上面写错了，是helloword.jsp不是hello.jsp错误如下  org.apache.jasper.JasperException: Exception in JSP: /helloword.jsp:1310: <html:base/>
    11: </head>
    12: <body bgcolor="white">
    13: <html:form  action="/helloword.jsp"  method="post">
    14:       <html:text property="mybeanvariable1" />
    15:       <html:submit value="aa" />
    16:       <html:reset value="aa" />

  3.   

    如果用了struts tag就不要写.do了.如下
    <html:form  action="/HellowordAction"  method="post">
    如果用了html自己的tag就要写.do了.如下
    <form  action="/HellowordAction.do"  method="post">

    dog() 把问题回答的很准确，这才是问题的真正之所在。struts html:form标签直接就在struts-configs.xml中寻找合适的action，而不需要通过web.xml处理*.do的映射了。
