APACHE POI读取Excel 2007

#1. 使用apache poi 3.11 读取Excel 2007内容

　　##1.使用到的jar

　　##2.出现的问题:org.apache.poi.POIXMLException: java.lang.reflect.InvocationTargetException

　　　　原因:         与xbeans-2.2.0冲突.

　　　　解决方案 : 删除xbeans-2.2.0

#2.使用jxl.jar 读取Excel 2003 的内容  . (PS:jxl.jar 不能读取Excel2007的内容)

import jxl.Sheet;
import jxl.Workbook;
