Automating input form generation

I am currently trying to develop (in a very short space of time) a way of dynamically building up a user interface from within a servlet.

This user interface is needed to allow a user to input the required details to then construct an XML instance of the information gathered.

I have been looking at some of the parsers available but these do not seem to support the direct parsing of XSD files, this leaves me somewhat at a loss as to where to go from here??
