Re: Good File Upload Example

For some reason, my previous mail doesn't show, so I'll try this
again. To upload, use the blobstore.
use all the example code except index.jsp from this page:
http://code.google.com/appengine/docs/java/blobstore/overview.html
replace index.jsp with a gwt file similar to the example in this page:
http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/user/client/ui/FileUpload.html

Change this line in Upload.java from
BlobKey blobKey = blobs.get("myFile");
to
BlobKey blobKey = blobs.get("textBoxFormElement");

Delete parts of FileUpload that involve the listbox.

Also, use an RPC call to get the form action url. The server side code
for the RPC call should look like this:
return blobstoreService.createUploadUrl("/upload");

Hope this helps :)
