,而JSP頁面的樣子

<%@ page import="edu.Customer" %>
<% if (session.getAttribute("customer") != null) {

<% }%>
我知道很多人在這裏發佈了同樣的問題,但我肯定肯定Customer.java在/WEB-INF/classes/edu/Customer.java下。那麼這裏還有其他配置問題嗎?我使用連接到tomcat的IIS。我可以到文件好,但我不能編譯JSP。 預先感謝您。
謝謝你的評論。我試圖在cmd中運行javac命令,並且它給了我javac甚至在我設置了javac.exe路徑後仍然無法識別。你碰巧知道問題在哪裏? – TitanTheYaphet 2012-04-06 03:35:53
