我在struts应用程序中使用了tiles。 我犯了这样的错误

Servlet.service() for servlet [jsp] in context with path [/Sample_Struts2] threw exception [javax.servlet.ServletException: javax.servlet.jsp.JspException: Error executing tag: Attribute 'header' not found.] with root cause
struts.xml

 <package name="tiles-sample" extends="tiles-default">
<result-types>
    <result-type name="tiles"
        class="org.apache.struts2.views.tiles.TilesResult" />
</result-types>

<action name="*Link" method="{1}" class="com.sample.TilesAction">
    <result name="welcome" type="tiles">welcome</result>
    <result name="friends" type="tiles">friends</result>
    <result name="office" type="tiles">office</result>
</action>
我使用的是struts 2.3.1.2版本。 我不知道到底是什么问题。 任何人都能帮上忙吗？

在struts.xml中：

in struts.xml : 

<action name="*Link" method="{1}" class="com.sample.TilesAction">
    <result name="welcome" type="tiles">helloWorld</result>
    <result name="friends" type="tiles">friends</result>
    <result name="office" type="tiles">office</result>
</action>

in tile.xml 

<definition name="helloWorld" template="/TilesSample.jsp">
    <put-attribute name="header" value="/Header.jsp"/>   
      <put-attribute name="menu"   value="/Menu.jsp"/>
      <put-attribute name="body"   value="/Body.jsp"/>
      <put-attribute name="footer"   value="/Footer.jsp"/>
  </definition> 

<definition name="friend" extends="helloWorld">   
      <put-attribute name="header" value="/Header1.jsp"/>   
      <put-attribute name="menu"   value="/Menu1.jsp"/>
      <put-attribute name="body"   value="/Body1.jsp"/>
      <put-attribute name="footer"   value="/Footer1.jsp"/>
  </definition>  
<definition name="office" extends="helloWorld">   
      <put-attribute name="header" value="/Header2.jsp"/>   
      <put-attribute name="menu"   value="/Menu2.jsp"/>
      <put-attribute name="body"   value="/Body2.jsp"/>
      <put-attribute name="footer"   value="/Footer2.jsp"/>
  </definition>

在tile.xml中
您是否创建了Header.jsp并将其放置在正确的位置？是的，我创建了Header.jsp文件。我只把它放在正确的地方。
