How to do this JSP code <%= session.getAttribute("attributeName") %> in Expression Language where stuff goes like ${blabla}
如何在表达式语言中执行此JSP代码<%= session.getAttribute(“attributeName”)%>,其中的内容类似$ {blabla}
Forgot to say that I actually tried the ${sessionScope.attributeName}, btw the attribute value is a String and was set by session.setAttribute("attributeName", "EditSession123"); and to check on that the value was sent right I created a jsp 1.0 file and used <%= session.getAttribute("attributeName") %> which was working but when I used JSP 2.0 nothing appears.

I'm beginning to question my header definitions ? it's auto generated from Eclipse
我开始质疑我的标题定义?它是从Eclipse自动生成的
