请教JSTL标签问题
在JSP里，用<HTML：SELECT>就能把LIST里的值遍历出来，用<select>+<c:foreach>标签就不行，JSP页面的代码如下，请高手多多指教
<%@ page language="java"%>
<%@ page contentType="text/html;charset=GB2312"%>
<%@ page import="java.util.*"%>
<%@ page import="com.hwhd.entity.Lesson"%>

prefix="bean"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html"

String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
List list = (List)request.getAttribute("list");
if(list != null){
System.out.println("Test is success!");
for(int j = 0;j<list.size();j++){
Lesson l = (Lesson)list.get(j);
System.out.println("term--->"+l.getTerm()+"|||id--->"+l.getId());

Lesson l = (Lesson) tt.get(i);
System.out.println(l.getStudent_type());
}
}
