To post the file, it HAS to be a multipart (which is why you need ENCTYPE), but when it is multipart, you have to do some extra work to extract the parameters out (as the parameters are stored in a Part in the request, not just in the request)

You are probably better off using something like:

http://jakarta.apache.org/commons/fileupload/

which is a library to handle just this type of thing :-)

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Download:  http://www.mirror.ac.uk/mirror/ftp.apache.org/jakarta/commons/fileupload/binaries/commons-fileupload-1.0.zip

Extract the file commons-fileupload-1.0.jar, and put it in WEB-INF/lib of your webapp

Follow the instructions on http://jakarta.apache.org/commons/fileupload/using.html
