public class TreeNode {
       String linepre = "";
       String linenext = "";
       String lineid = "";
        TreeNode father;

        TreeNode child;

        TreeNode brother;
        public TreeNode()
        {
            father=null;
            child=null;
            brother=null;
        }
}// 树结点结构
这样一个类,在jsp页面中怎么用它定义一个类,然后对它初始化啊.
<%@ page import="SQLServer.TreeNode"%>
.................
if(rs.next()){
            node.lineid=rs.getString("lineid");
            node.linepre=rs.getString("linepre");
            node.linenext=rs.getString("linenext");
            //treeview.creatTree(node,end)；
            //treeview.thoghTree(node,end);
          %>
为什么实现不了啊?
