Java Poi 导出失败问题

程序是在网上看的，poi在addPicture时就报错，一直过不了。

直接上代码
ByteArrayOutputStream byteArrayOut = new ByteArrayOutputStream();
BufferedImage bufferImg = ImageIO.read(new File("d:\\2.jpg") );
ImageIO.write(bufferImg,"jpg",byteArrayOut);

//设置图片大小，位置
HSSFClientAnchor anchor = new HSSFClientAnchor(1,1,1,1,(short) 1,1,(short)1,1);
anchor.setAnchorType(0);

patriarch.createPicture(anchor , wb.addPicture(byteArrayOut.toByteArray(),HSSFWorkbook.PICTURE_TYPE_JPEG));

报下以错误
java.lang.ClassNotFoundException: org.apache.commons.codec.digest.DigestUtils

缺少common-codec.jar包或者版本不对
