  private String value;

  public void Values(){

推荐答案

您需要提交的东西从你形成有东西在你的行动。看看 http://www.w3schools.com/html/html_forms.asp 。

You have to submit something from you form to have something in your action. Have a look http://www.w3schools.com/html/html_forms.asp.

如果您有属性名称动作键，这个属性被设置了一些值，如斯密特然后在jsp中可以使用＆LT; S：房地产/＆GT; 标签来显示该值，并隐藏字段提交此值回的动作。

If you have action with property name and this property is set with some value e.g. Smit then, in jsp you can use <s:property/> tag to display this value and hidden field to submit this value back to the action.

<sx:div>
  <div id="Values">
    <div id="Value">Value is:<s:property value="name"/></div>
    <s:form action="SubmitValue" >
      <s:hidden name="name"/>
      <s:submit/>  //When I click on this one, it does not send the value to class
    </s:form>
</sx:div>
