解决方案 »

  1.   

    找不到映射或FormBean，把HelloWord.jsp 和配置的xml文件贴出来看看。
      

  2.   

    path="/HelloWord"   /*改为path="/HelloWorld"*/
      

  3.   

    不会吧 我所有的都是HelloWord~~
    怎么要改HelloWorld~~我改也还是没用~~
      

  4.   

    <html:form action="/Helloworld">    //这里Helloworld，要么是你写错了。或者把这里改为HelloWord
      

  5.   

    <action-mappings>
            <action
                attribute="HelloWordForm"
                name="HelloWordForm"
                path="/HelloWord"
                type="test.struts.HelloWordAction">
                <forward name="sucess" path="/HelloWord.jsp" />
            </action>
        </action-mappings>
    <html:form action="/Helloworld">这里的action属性值和上面的映射path要一致

    多谢楼上的回复 还是不行~~

    HelloWord.jsp
    <%@page contentType="text/html;charset=gb2312"%>
    <%@taglib uri="/WEB-INF/struts-bean.tld"prefix="bean"%>
    <%@taglib uri="/WEB-INF/struts-html.tld"prefix="html"%>
    <html>
    <head>
    <title>Hello world</title>
    </head>
    <body>
    <html:form action="/HelloWord">
    请输入HelloWord:<html:text property="word"/><html:submit/>
    </html:form>
    <hr>
    <bean:write name="HelloWordForm" scope="session"property="word"/>
    </body>
    </html>
      

  8.   

    <bean:write name="HelloWordForm" scope="session"property="word"/>TO：<bean:write name="HelloWordForm" scope="session" property="word"/>
      

  9.   

    <bean:write name="HelloWorldForm" scope="session"property="world"/>你这句里面的HelloWorldForm对象，在HelloWordAction代码里面再加一句话：request.getSession.setAttribute("HelloWorldForm","nice to see you!")，
    这样在jsp中应该会显示nice to see you!的，很多东西都是通过在HelloWordAction里通过setAttribute（）这个函数将有关值返回到页面的。
      

  10.   

    <bean:write name="HelloWordForm" scope="session"property="word"/>我上面的回答还没注意到吗？楼主原来是少一个空格：<bean:write name="HelloWordForm" scope="session"          property="word"/>
      

  11.   

    加上scope="request"这样应该可以了吧
     <action-mappings>
            <action
                attribute="HelloWordForm"
                name="HelloWordForm"
                scope="request"
                path="/HelloWord"
                type="test.struts.HelloWordAction">
                <forward name="sucess" path="/HelloWord.jsp" />
            </action>
        </action-mappings>
