import java.io.*;import java.util.*;import javax.servlet.*;import javax.servlet.http.*;public classdownload extends httpservlet{public void doget(httpservletrequest request, httpservletresponse response) throws ioexception, servletexception{try{//这边你不妨做些其余的工作response.setcontenttype("application/octet-stream");response.setheader("content-disposition", "attachment; filename=\"你要在生存窗口中表露的生存文献名\"");servletoutputstream out = response.getoutputstream();bufferedreader br=new bufferedreader(new filereader(要载入的的文献名));string line=br.readline();while (line!=null){out.write(line.getbytes());out.println();line=br.readline();}out.close();br.close();}catch (exception e){system.out.println(e);}}public void dopost(httpservletrequest request, httpservletresponse response) throws ioexception, servletexception{doget(request, response);}}即是这么大略版主提醒：这边的代码在做二进制文献载入的功夫会有题目，由于这边运用到了bufferedreader，而这个类是为读“字符”而筹备，须要按“字节”来读的功夫，请运用inputstream来做。
