XML Java Apache Web Tomcat

先贴出代码出来看看.
首先是一个Folders.xml文件:

<?xml version="1.0" encoding="gbk"?>
<Folders>
<Folder stepid="5" beginEid="1.0.0." endEid="8.0.0." folderId="88" folderName="文件夹一" />
<Folder stepid="5" beginEid="8.0.0." endEid="20.0.0." folderId="89" folderName="文件夹二" />
</Folders>

一下是解析XML文件的类.采用jdom解析.然后封装到一个Bean对象中.最后返回一个ArrayList集合.集合里面是一个个Bean对象. XmlConfig.Java

package JdBudget.OuterWeb.Config;

import java.util.*;
import java.io.*;
import JdBudget.OuterWeb.bean.*;
import JdBudget.OuterWeb.bean.Folder;

import org.jdom.output.*;
import org.jdom.input.*;
import org.jdom.*;

public class XmlConfig {
  
  public XmlConfig(){}
  ArrayList dataList = null;
  //解析Folders.xml
  public ArrayList getFoldersInfo(String path) {
    dataList = new ArrayList();
    Folder dataValue = null;
    try {

      SAXBuilder builder = new SAXBuilder(false);
      Document read_doc = builder.build(new FileInputStream(path));
      Element root = read_doc.getRootElement();
      List Folders = root.getChildren("Folder");
      for (int i = 0; i < Folders.size(); i++) {
        Element e = (Element) Folders.get(i);
        dataValue = new Folder();
        dataValue.setFolderId(e.getAttributeValue("folderId"));
        dataValue.setEndEid(e.getAttributeValue("endEid"));
        dataValue.setBeginEid(e.getAttributeValue("beginEid"));
        dataValue.setStepid(e.getAttributeValue("stepid"));

        System.out.println(e.getAttributeValue("folderId"));
        System.out.println(e.getAttributeValue("folderName"));
        System.out.println(e.getAttributeValue("endEid"));
        System.out.println(e.getAttributeValue("beginEid"));
        System.out.println(e.getAttributeValue("stepid"));


        dataList.add(dataValue);
      }
    }
    catch (Exception dom) {
      System.out.println("getFoldersInfo Err" + dom.toString());
    }
    return dataList;

  }

  //解析Reports.xml
  public ArrayList getReportsInfo(String path) {
    dataList = new ArrayList();
    Report dataValue = null;
    try {
      SAXBuilder builder = new SAXBuilder(false);
      Document read_doc = builder.build(new FileInputStream(path));
      Element root = read_doc.getRootElement();
      List Reports = root.getChildren("Report");
      for (int i = 0; i < Reports.size(); i++) {
        Element e = (Element) Reports.get(i);
        dataValue = new Report();
        dataValue.setItemId(e.getAttributeValue("ItemId"));
        dataValue.setVariant(e.getAttributeValue("Variant"));
        dataValue.setType(e.getAttributeValue("Type"));
        dataList.add(dataValue);
      }
    }
    catch (Exception dom) {
      System.out.println("getReportsInfo Err" + dom.toString());
    }
    return dataList;

  }

  public static void main(String[] args){
    XmlConfig xmlconfig = new XmlConfig();
  File f = new File("");
  ArrayList list = new ArrayList();
  list = xmlconfig.getFoldersInfo(f.getAbsolutePath()+f.separator+"MultiReport"+f.separator+"config"+f.separator+"Folders.xml");

  }
}

我用XmlConfig.java文件中的main方法测试,能得到争取得解析结果 .
如:

88

文件夹一

8.0.0.

1.0.0.

5

89

文件夹二

20.0.0.

8.0.0.

5

但是当我在createreport.jsp里面调用执行

XmlConfig xConfig = new XmlConfig();

时程序就已经报错误.
错误描述如下:

在 main函数里面执行都可以返回正确得结果.现在怎么只是实例化XmlConfig类就报错误呢....
网上看到说时jdom的版本问题.我也在webspere的安装目录下面找到了103k的jdom包替换了原来143K的jdom安装包.现在问题仍然存在 ..
请看下,分析下..!
小弟很急..
谢谢..
