The problem is that the parts of the MultiParser is an interface to 1 single Part
object (I
guess to save memory). So everytime you do mp.readNextPart() it will override this one
object. So what you should do is to deal with the file right away. See the inline
correction
in your code.
I think that should make it work...

// write the file right away, before part gets a
new value through
the method mp.readNextPart()
if (fileName != null) {
long size = filePart.writeTo(uploadDir);
}

// Moved upwards
// File uploadDir = new File("/home/www/dramamurthy/sitebuilder/WEB-INF/Uploads/");
// if (!uploadDir.exists()) {
// uploadDir.mkdir();
// }
// Moved to inside the while loop
// if (fileName != null) {
// long size = filePart.writeTo(uploadDir);
// }
