Hi,
I basically want to upload an excel file to blobstore and then parse the
file using POI.
I have uploaded the excel file to the blob store using the following .jsp
code
<%
BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
%>
<form action="<%= blobstoreService.createUploadUrl("/productmetasaver") %>"
method="post" enctype="multipart/form-data">
<input type="text" name="foo">
<input type="file" name="myFile">
<input type="submit" value="Submit">
</form>
This part works fine(I can see the file in the blobstore) but when I try to
access the file using the below code :
public class ProductMetaSaverServlet extends HttpServlet {
// private BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
java.util.Map<java.lang.String,java.util.List<BlobKey>> blobs =
blobstoreService.getUploads(req);
BlobKey blobKey = blobs.get("myFile").get(0);
if (blobKey == null) {
resp.sendRedirect("/");
} else {
resp.sendRedirect("/serve?blob-key=" +
blobKey.getKeyString().trim());
}
java.util.Map<java.lang.String,java.util.List<FileInfo>> filelist =
blobstoreService.getFileInfos(req);
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
for(String filename : filelist.keySet())
{
out.print(filename);
out.print(filelist.get(filename));
}
}
My serve method :
public class Serve extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 1L;
private BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
@Override
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws IOException {
BlobKey blobKey = new BlobKey(req.getParameter("blob-key"));
blobstoreService.serve(blobKey, res);
}
}
I get the following error :
*(Error: Not Found*
*The requested URL **
/upload-success?blob-key=AMIfv94Mrs9e1vk65ws-9jRek-QyhZ14tx3cNI5OgCj1rJvuS_ZLRq77tabioZTWRsAlTx_g6R2R1X1pyEIg7ckYsq_1pXmfFmwAilcPaZ7pYZKKRFOew3iwyCgOGfO4ScgJ-OaYm3kWWF_s9GaZwQmWcYNlwBLDpQ
** was not found on this server.) *
*
*
Can someone please point out what im doing wrong here.
I just need the file path of the uploaded file so that I can pass it to
apache POI.
Thanks,
Anuja
