   category.jsp
   --------------------------------
   <frameset rows="*" cols="180,*" frameborder="yes" framespacing="1px" border="0" >
   <frame name="menuFrame" src="../categoryAction.jspx?method=loadAllMenus" scrolling="No" noresize="noresize" >
   <frame name="deatilFrame" src="categoryDetail.jsp" >
   ----------------------------------

categoryDetail.jsp
----------------------------------
   <html:form action="categoryAction.jspx?method=saveCategory" >
          ... ...
      <html:form>
-----------------------------------

struts-config-admin.xml:
------------------------------------
     <action
      attribute="categoryForm"
      input="/product/categoryDetail.jsp"
      name="categoryForm"
      parameter="method"
      path="/categoryAction"
      scope="request"
      validate="false"
      type="com.book.web.struts.action.CategoryAction" >

       <forward name="viewMenu" path="/product/categoryMenu.jsp" />
       <forward name="succ" path="/product/categoryDetail.jsp" />
      </action>

-----------------------------------
      以链接的形式访问正确, 直接访问action http://localhost:8080/promtion/admin/categoryAction.jspx?method=saveCategory 正确.

     但把action 放到jsp页面中就出错, http://localhost:8080/promtion/admin/category.jsp

我调试了struts 源码发现刚开始也能取到module 的name 值为admin, 但在后续处理的时候就把该值丢了, 于是struts只能从struts-config.xml 文件读取, 而不是从struts-config-admin.xml中读取action, 所有就找不到了action, 抛出异常.

struts 1.2 我还有待测试, 不知道是否有同样的问题.?

其它相同问题的网友发言:

    然后调用reset方法设置该form对象的属性;
    再从jsp页面取得属性并set bean的属性,
    然后再调用validate方法(validate = true),验证出错, 则直接返回到input 页面,正确则调用action的方法进行出来.
