在Struts中应用Tiles框架，利用ForwardAction进行跳转，但出现Path index-definition does not start with a "/" character的问题。此处的index-definition 是在tiles-defs.xml中定义的，作为struts-config中Action配置的parameter属性的值。
上述方法引用自网络，但运行中会出现[color=red]java.lang.IllegalArgumentException: Path index-definition does not start with a "/" character[/color]异常。
代码如下：


  <action-mappings>
    <action path="/index"
		type="org.apache.struts.actions.ForwardAction"
		parameter="index-definition">
	</action>
  </action-mappings>


<definition name="index-definition" path="/layout.jsp">
<put name="sidebar" value="sidebar.jsp"/>
<put name="header" value="header.jsp"/>
<put name="content" value="indexContent.jsp"/>
<put name="footer" value="footer.jsp"/>
</definition>


严重: Servlet.service() for servlet action threw exception
java.lang.IllegalArgumentException: Path index-definition does not start with a "/" character
