为什么不能打印 There was ... ?
谢谢
------解决方案--------------------------------------------------------
不能打印就是myException 为空了。。。。。
------解决方案--------------------------------------------------------
<c:if test="${myException != null}">
There was an exception : ${ myException.message } <br/>
</c:if>
test="${myException != null}"
把这里面的空格都去掉
------解决方案--------------------------------------------------------
我表示很担心楼主的这行代码：<% int x = 10/0; %>
用10除以0 有意义吗？
------解决方案--------------------------------------------------------
test=" ${myException != null}"
" 和$之间不能有空格，也就是说test=" true" 这样带空格的值，是不对的
应该为test="true"才对，我试过了，改了之后已经可以打印There was ... 了
