I try to save file information such as filename,blobkey,Date when
uploading a file
, and print all of that later on JSP. It works flawless on localhost,
but after deploy to app engine
my JSP can not dynamic create filename, can anyone tell me what's
wrong, thx very much
below is part of my code
upload code:
skip...
String subjectID = req.getParameter("subjectID");
Map<String, BlobKey> blobs = blobstoreService.getUploadedBlobs(req);
BlobKey blobKey = blobs.get("myFile");
if (blobKey == null) {
res.sendRedirect("/");
} else {
BlobInfo info = new BlobInfoFactory().loadBlobInfo(blobKey);
String fileName=info.getFilename();
fileName=new
String(fileName.getBytes("ISO-8859-1"),"UTF-8");
Date createDate=info.getCreation();
SubjectFile a=new SubjectFile();
a.save(subjectID, blobKey,fileName,createDate);
res.sendRedirect("./JSP/list2.jsp");
JSP:
List<SubjectFile> subjectlist=sub.getSubjectfile();
for(SubjectFile a:subjectlist){
String fileName=a.getFileName();
out.println("<a
href=/serve?key="+a.getBlobKey().getKeyString()
+ ">"+fileName+"</a><br>");
}
