Answer 1

Both the file and text values are included in the binary inputstream of the request. The parametermap is always empty.
There exist 3rd party API's to parse multipart/form-data streams, such as [Apache Commons FileUpload API|http://commons.apache.org/fileupload].
Read at least the 'User Guide' and 'Frequently Asked Questions' sections.
