I have developed an application in google app engine, in which I have a file upload option, I am able to upload files and can view them afterwards. But when I move it to real environment (into google appengine) the file upload is not working. it is showing the following error with HTTP 500 error.
Error: Server Error
The server encountered an error and could not complete your request.
If the problem persists, please report your problem and mention this error message and the query that caused it.

It is resolved!!!
This was caused, because I was creating Text object with NULL string value, I have converted my file content into a string, if there is no file uploaded for any of the file upload field this string is coming as a NULL, when I am persisting object with Text object has NULL value, then app engine was trying to throw an exption.
No. No. No. No. Changed my mind. Wanna come down. To see this tiny ad:
