The taglib directive below imports the JSTL library. If you uncomment it,
you must also add the JSTL library to the project. The Add Library... action
on Libraries node in Projects view can be used to add the JSTL 1.1 library.

This example uses JSTL, uncomment the taglib directive above.
To test, display the page like this: index.jsp?sayHello=true&name=Murphy
--%>
<%--
<c:if test="${param.sayHello}">
<!-- Let's welcome the user ${param.name} -->
Hello ${param.name}!
</c:if>
--%>

用JAVAMAIL作了个邮件传送的例子却怎么也实现不了，填写了信息后到JavaMail.jsp就什么也不显示了也没有错误提示。我用的126的油箱。是不是写的有问题请高手指教以下。 本人万分感激！！！谢谢
