在B/S模式下使用java代理导入excel文件的实现方法及代码
用java代理获取附件输入流EmbeddedObject.getInputStream(),使用开源文件的Java Excel API 来读取excel
jxl.jar的下载地址http://www.andykhan.com/jexcelapi/download.html，lotus8最高支持2.68版本的
代码如下：
import lotus.domino.*;
import java.io.*;
import java.text.SimpleDateFormat;
import java.util.Date;
import jxl.*;
import jxl.read.biff.BiffException;
