Getting response code 404 on upload image on server in blackberry

I want to upload an image to a server. I used the code from SO question: Blackberry jde : how to upload an image in server using MultipartPostData

But the image开发者_Go百科 is not uploaded to the server.

Are you 100% certain that the URL you are POSTing to is valid?

HTTP 404 is "resource not found"; for a POST that would typically mean the CGI program, script or controller is not at the path you've given.
