解决方案 »

  1.   

    你要看看你的/template/LoginSuccess.jsp存在不，如果存在看看里面的内容是不是空
      

  2.   

    把struts-config.xml貼上來。
     最有可能的是：你的execute方法返回的ActionForward對象是null值
      

  3.   

    不是空的~
    LoginSuccess.jsp内容
    <%@ page contentType="text/html; charset=gbk" language="java" %>
    <%@ taglib uri='/WEB-INF/tlds/MediaStore_template.tld' prefix='mstemplate' %><mstemplate:insert template='/template/MediaStoreTemplate.jsp'>
      <mstemplate:put name='content' content='/jsp/LoginSuccess.jsp'/>

  7.   

    暈死，你不寫execute方法難道是直接鏈接跳轉的麽？？
      

  8.   

    你最好先找本struts書過一遍，搞清楚大致脈絡再找例子上手。
      

  9.   

    完整的action<action path="/aFullAction"
    type="somePackage.someActionClass">
    name="someForm"
    input="someJSP.jsp"
    <forward name="successful" path="someJSP.jsp"/>
    <forward name="failed" path="someOtherJSP.jsp"/>
    </action>首先，Struts的ActionServlet接收到一个请求，然后根据struts-config.xml的配置定位到相应的mapping（映射）；接下来如果form的范围是request或者在定义的范围中找不到这个form，创建一个新的form实例；取得form实例以后，调用其reset ()方法，然后将表单中的参数放入form，如果validate属性不为false，调用validate()方法；如果validate()返回非空的ActionErrors，将会被转到input属性指定的URI，如果返回空的ActionErrors，那么执行Action的execute() 方法，根据返回的ActionForward确定目标URI。这样做的效果是：execute()仅当validate()成功以后才执行；input属性指定的是一个URI。
