You should really take Howard's advice and look at how the upload
component works. You can't just change the content type of the form
because this changes how servlets behave. Try googling for "servlet
multipart/form-data" and find that since the beginning of time people
have been writing libraries to work around the gap in the java
servlet's handling of multipart/form-data...
Essentially getParameter stops working and tapestry can't find it's
hidden form fields. You could grab the source for the upload component
and change the offending bits...
