List fileItems = fu.parseRequest(request);

out.println("TOTALFILES:" + fileItems.size() + "<br>");

Iterator itr = fileItems.iterator();

fu.setSizeMax(1000000); // throw exception if > 1 Mb

while (itr.hasNext()) {
FileItem fi = (FileItem) itr.next();

if (!fi.isFormField()) {
// only process files here, not form fields
docfilename = fi.getName();
docsize = fi.getSize();
contentsdf = fi.getString();
}
if (docsize > 0) {
out.println("FILENAME:" + docfilename + "<br>");
out.println("FILESIZE:" + docsize + "<br>");
out.println("FILECONTENT:" + contentsdf + "<br>");
}
}

Go to the Apache commons.fileupload page and carefully read their installation
