this jsp page used clone rows , add files. last uploaded file's name printed in console when used

multipartrequest mreq = new multipartrequest(request, "d:/pics", 1024 * 1024 * 1024); enumeration files = mreq.getfilenames(); while (files.hasmoreelements()) {   system.out.println("\nhasmoreitems");   string name = (string) files.nextelement();   string filename = mreq.getfilesystemname(name);   system.out.println(filename);

this loop gets executed once files overrided in enumeration files.
