Please help me

Not really giving us much to go on.

Without any actual information, it looks like your form definition doesn't match what's coming in from the request.

I would suggest fixing the spelling of "setUpload", though.

Hi

Hi david I putting my code snippet that would be helpful to you.
Thanks

Please UseCodeTags when posting code or configuration. Unformatted code and configuration is very difficult to read. You can edit your post to include them by using the

button.

Note, however, that this code doesn't actually help: the error occurs before your action is being executed (see the stack trace you posted previously).

I'd also urge you to refactor your action method: it's too long and is responsible for too many things.
