这是页面上的连接，我传了个路径和文件名
Java代码
1. <%
2. String filename = ameter("filename");//"";
3. String filepath = ameter("filepath");//"d:";
4. int i = 0;
5. tentType("application/octet-stream");
6. der("Content-Disposition","attachment;filename = "+filename);
7. putStream fileInputStream = new putStream(filepath+filename);
8. while((i= ()) != -1){
9. (i);
10. }
11.%>
这是被调用的，这个jsp就是执行直接下载文件的不管是txt还是word文档都可以直接下载
这个东东是我在一个专业编程杂志的网站花３块钱买的，嘿嘿．没办法，项目急用，今天上来看到有人需要赶紧发出来，希望３，４楼还能看到．
