Cannot find bean org.apache.struts.taglib.html.BEAN in any scope
提问by user3358472
I have a form which has five tabs. In one of the tabs(background.jsp) on change of a checkbox(be in checked or unchecked) I am trying to set the flag of (hasGenderChanged) in jsp to true and use a request type to send it to my java code.
我有一个有五个选项卡的表单。在更改复选框的选项卡（background.jsp）之一（处于选中或未选中状态）中，我试图将 jsp 中的 (hasGenderChanged) 标志设置为 true 并使用请求类型将其发送到我的 java 代码。
Below is the code structure. I am getting an error which reads: Cannot find bean org.apache.struts.taglib.html.BEAN in any scope in edit_Education.jsp. Below is the code structure. Any help will be greatly appreciated.
下面是代码结构。我收到一条错误消息：在 edit_Education.jsp 的任何范围内都找不到 bean org.apache.struts.taglib.html.BEAN。下面是代码结构。任何帮助将不胜感激。
Introduction.jsp has all the header tabs and at the end of it has On click of save button in this page I want to send if a check box has been changed during filling up a form. If changed want to send true to java component from JSP.
Introduction.jsp 包含所有标题选项卡，并在它的末尾单击此页面中的保存按钮，如果在填写表单期间更改了复选框，我想发送。如果更改要从 JSP 向 java 组件发送 true。
In edit_Education.jsp:
在 edit_Education.jsp 中：
<template: insert template='education/Introduction.jsp'>
<logic:equal name="educationForm" property="selectedOption" value="0">
<template:put name='content-area' content='education/background.jsp'/>
</logic:equal>
<logic:equal name="educationForm" property="selectedOption" value="1">
<template:put name='content-area' content='education/eduqualification.jsp'/>
</logic:equal>
<logic:equal name="educationForm" property="selectedOption" value="2">
<template:put name='content-area' content='education/workexperience.jsp'/>
</logic:equal>
</template: insert
Since the forms on each tab are huge I want to trigger an action only if a checkbox has been checkbox in background.jsp
由于每个选项卡上的表单都很大，因此我只想在 background.jsp 中的复选框已被选中时触发操作
In background.jsp
在后台.jsp
Inside the html tags of a checkbox this is the function I have
在复选框的 html 标签内，这是我的功能
<script>
function validate(){
document.educationForm.hasGenderChanged.value="true";
}
<html:form action="/processEducationAction" target="CONTENT-AREA">
<html: hidden property="hasGenderChanged"/>
<input type="hidden" name="hasGenderChanged" value="" scope="request"/>
</script>
<TR>
<html:checkbox property="selectOptions.selectGender" onchange="validate()"/>
<bean:message key="education.selectedOptions.label.selectGender"/>
<TR>
</html:form>
In educationForm.java I have a boolean hasGenderChanged; variable and setters and getters for this.
在educationForm.java 我有一个布尔值hasGenderChanged；变量和setter 和getter 为此。
I am not sure how this value, hasGenderChanged in background.jsp can be made accessable to in edit_Education.jsp.
我不确定如何在edit_Education.jsp 中访问background.jsp 中的hasGenderChanged 这个值。
I am a newbie in Struts.Thanks in advance for the help.
我是 Struts 的新手。提前感谢您的帮助。

perhaps you should try to place your tags inside a form
也许您应该尝试将标签放在表单中
<template: insert template='education/Introduction.jsp'>
<html:form>
<logic:equal name="educationForm" property="selectedOption" value="0">
<template:put name='content-area' content='education/background.jsp'/>
</logic:equal>
<logic:equal name="educationForm" property="selectedOption" value="1">
<template:put name='content-area' content='education/eduqualification.jsp'/>
</logic:equal>
<logic:equal name="educationForm" property="selectedOption" value="2">
<template:put name='content-area' content='education/workexperience.jsp'/>
</logic:equal>
</html:form>
</template: insert>
please notice the two <html:form> </html:form>tags
请注意这两个<html:form> </html:form>标签
