1.jsp
<%String[] arry1 = String[]{"deco3942","123456","tom"};%>
<%String[] arry2 = String[]{"tank123","382839","jhon"};%>
...
<%List<String[]> list = new LinkedList<String[]>();%>
<%list.add(arry1);%>
<%list.add(arry2);%>
<%session.setAttribute("arrlist",list);%>
...(2.jsp)
<%List<String[]> list = (List<String[]>)session.getAttribute("arrlist");%>
...
session为jsp内置对象可以直接使用,
大概就是这个样子,后面不用写了吧
