动态dtree不显示，麻烦帮我看看，愁死了！！！！！！！
这是生成xml的servlet：
package com.handler;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.dao.DaoTest;
import com.dao.Nodes;
public class NodesPrint extends HttpServlet {
private static final long serialVersionUID = 1L;
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
System.out.println("调用servlet生成xml文件");
request.setCharacterEncoding("utf-8");
response.setContentType("text/xml;charset=utf-8");
//response.setHeader("ContentType","text/xml");
PrintWriter out = response.getWriter();
DaoTest test = new DaoTest();
ArrayList list= test.getNodeInfo();
//System.out.println("#"+list.size()+"#");
if(list!=null&&list.size()>0){
//System.out.println(list.size()+"是长度");
out.println("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
out.println("<nodes>");
for(int i=0;i<list.size();i++){
Nodes node = (Nodes) list.get(i);
//out.println("<node nodeId='1' parentId='1' hrefAddress='www.baidu.com'>节点</node>");
out.println("<node nodeId='"+node.getClassid()+"'parentId='"+node.getParentid()+"'hrefAddress='"+node.getFormid()+"'>"+node.getClassname()+"</node>");
}
out.println("</nodes>");
}
}
}
这是显示的jsp

帮我看看吧
[解决办法]
用firebug或是调JS的看下
为啥不显示，是引入JS包错了，还是你数据填错了
[解决办法]
out.println("<node nodeId='"+node.getClassid()+"'parentId='"+node.getParentid()+"'hrefAddress='"+node.getFormid()+"'>"+node.getClassname()+"</node>");
你自己的第一node的parentId是不是0？因为 tree.add(0,-1,"这是根节点");
------解决方案--------------------
先手动搞几条数据，看能显示不，能显示了再按规律拼。
