Can we upload documents from Flex to Google app engine blobstore?

I am working in Flex with Java. I have a question about Flex application running in Google app engine. Can we upload documents开发者_Python百科 from a Flex client to Google app. engine blobstore?

Yes, you can.

If you have written server side code using Java (or Python), and using HTTP for uploading files to server. I mean that there is need to be an server side code, because you can't access database directly from Flex.

If you can create and submit multipart forms in Flex, you can upload to the blobstore. From Flex's point of view, there is no difference between uploading files to the blobstore and uploading them anywhere else. You do not access the blobstore in Flex - you just upload to a URL provided by your server-side code.

If you've tried this and are having specific problems, you should update your post with details.
