java 对word、excel的操作

Question

    大家好，我想问一个问题。最近感觉好奇，想用Java操纵Excel，我在网上找到了一些源码，但是在Eclipse中运行时有四个包找不到，不知道什么原因，请大家帮忙解决！
    四个包是：org.apache.poi.hssf.usermodel.HSSFWorkbook;
            org.apache.poi.hssf.usermodel.HSSFSheet;
            org.apache.poi.hssf.usermodel.HSSFRow;
            org.apache.poi.hssf.usermodel.HSSFCell;
    想问：1、下载的网站是什么（或者发到：[email protected]）
           2、这个包应该放到哪个目录下

public class Excel{
 public static void writeExcel(OutputStream os) throws Exception{
  jxl.write.WritableWorkbook wwb=Workbook.createWorkbook(os);
  jxl.write.WritableSheet ws=wwb.createSheet("title",0);
  jxl.write.Label labelc=new jxl.write.Label(0,0,"zhongguo");
  jxl.write.Label labelk=new jxl.write.Label(1,1,"kaka");
  ws.addCell(labelc);
  ws.addCell(labelk);
  jxl.write.WritableFont wfc=new jxl.write.WritableFont(WritableFont.ARIAL,20,WritableFont.BOLD,false,

  jxl.write.WritableCellFormat wcfFC=new jxl.write.WritableCellFormat(wfc);
  wcfFC.setBackground(jxl.format.Colour.GREEN);
  
  labelc=new jxl.write.Label(6,0,"中国爱我",wcfFC);
