我用的是eclipse(3.2)+myeclipse(5.1)
jdk(1.4.2_04)
tomcat(5.0.28)
jsp文件放在WebRoot下,java文件放在src的cn.com.shoppingonline包中,
.class文件放在classes的cn.com.shoppingonline包中.
其中一个left.jsp代码如下:
<%@ page contentType= "text/html;charset=UTF-8 " language= "java " %>
<%@ page import = "cn.com.shoppingonline.* " %>
<%@ page import = "java.util.* " %>
<%
List sortList = (List)session.getAttribute(Constants.SORT_LIST_KEY);
Sort sort = null;
%>
运行这个jsp文件报如下错误:
HTTP Status 500 -
