File Upload Exception - request doesn't contain a multipart/form-data or multipart/mixed stream, content type header is application/x-www-form-urlencoded

[Edward S]

Hey guys,

I am tryin to upload a JPG file and am getting this error:

org.apache.commons.fileupload.FileUploadBase$InvalidContentTypeException:the
request doesn't contain a multipart/form-data or multipart/mixed
stream,
content type header is application/x-www-form-urlencoded


let me explain what I am doing:

I have a JSP that has the form that does the file upload. the enctype on the
form is "multipart/mixed"
this JSP is included in a root JSP and the action submits the form to the
root JSP.

Root JSP has a controller, that processes the request. When it tries to
process this request, it gives me the above mentioned error.

Any idea, where I am going wrong?

thanks

Ed.
