Answer 2

<jsp:include page="Myfile/Hello.txt" >
 </jsp:include>
<jsp:include page="Myfile/Hello.txt" />应该说是一样的呀
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
理论上说确实是一样的，但是这里如果用
<jsp:include page="Myfile/Hello.txt" >
 </jsp:include>
这种形式，那么必须写成如下的形式
<jsp:include page="Myfile/Hello.txt" >
    <jsp:param name="" value=""/>
 </jsp:include>
这里name和value可以为null
