jsp页面传值取值问题request.getParameter无法取到jsp页面的值

1、首先确定 <%=id%>和 <%=name%> 两不为NULL
2、再次确定
<input type="hidden" name="id" id="id" value=" <%=id%>">??
和
<input type="hidden" name="name" id="name" value=" <%=name%>">??
是放在form 中

Java代码

1. SmartUpload upload =?new?SmartUpload(); ??
2. ?????try{ ??
3. ???? upload.initialize(config,?request, response); ??
4. ????// 允许上传的文件类型???
5. ???? upload.setAllowedFilesList("doc,xls,"); ??
6. ????// 拒绝上传的文件类型???
7. ???? upload.setDeniedFilesList("exe,bat,jsp"); ??
8. ????// 允许上传文件的单个最大大小???
9. ???? upload.setMaxFileSize(1024?*?1024?*?20); ??
10. ????// 允许上传文件的最大大小总和???
11. ????// upload.setTotalMaxFileSize(1024*1024*10);???
12. ????//上传数据???
13. ???? upload.upload(); ??
14. ???? } ??
15. ????catch?(SmartUploadException e){ ??
16. ???????? e.printStackTrace(); ??
17. ????????return; ??
18. ???? } ??
19. ??
20. ????Request?req = upload.getRequest(); ??
21. ???? String spid=(String)req.getParameter("teacherId"); ??
22. ?????????//.....???
23. ?????????//To do something??

这样就可以取得对应的值了.?
