Ok, then i share my server code as well, where i handle the multipart form:
String PDFFolder = "c:\\folder\\";
int maxSize = 300000;
String extensionRealFichero = null;
String contentType = null;
int idImagen = 0;
DiskFileUpload fu = new DiskFileUpload();
// maximum size before a FileUploadException will be thrown
fu.setSizeMax(maxSize);
// maximum size that will be stored in memory
fu.setSizeThreshold(4096);
// the location for saving data that is larger than
getSizeThreshold()
fu.setRepositoryPath(directorioPDF);
try {
List fileItems = fu.parseRequest(req);
// assume we know there are two files. The first file is a small
// text file, the second is unknown and is written to a file on
// the server
Iterator i = fileItems.iterator();
while (i.hasNext()) {
actual = (FileItem) i.next();
if (actual.isFormField()) {
//NORMAL ARGUMUENT RECIEVED
System.out.println("ARG-->" + actual.getFieldName() +
"="+ actual.getString());
paramsForm.setProperty(actual.getFieldName(),
actual.getString());
} else {
//FILE RECIEVED
System.out.println("Nombre Fichero recibido:" +
actual.getName()+ ".");
paramsForm.setProperty("nombreReal", actual.getName());
ficheroUpload = actual;
}
}
extensionRealFichero =
(actual.getName().substring(actual.getName().length()-3,actual.getName().length())).toUpperCase();
contentType = ficheroUpload.getContentType();
System.out.println("contentType:"+contentType);
System.out.println("extension:"+extensionRealFichero);
System.out.println("Ruta Final del
Fichero:"+directorioPDF+actual.getName());
ficheroUpload.write(new File(directorioPDF+actual.getName()));
hope it helps
