Why does not the MultipartFormDataRequest save information in the Hashtable?
0
I have 2 attributes in my JSP (path_Id & path_Proof_Of_Address), in these I send an image in each attribute.
But when saving them with the MultipartFormDataRequest in the Hashtable, if you reserve the size of 2, but only save a value in the first key (file_Id), discarding the image sent in the key file_Address.
MultipartFormDataRequest mrequest = null;
UploadBean upBean = null;
try {
mrequest = new MultipartFormDataRequest(request);
Hashtable files = null;
files = mrequest.getFiles();
System.out.println("Size of Hashtable: " + files.size());
Set<String> keys = files.keySet();
//Obtaining iterator over set entries
Iterator<String> itr = keys.iterator();
//Displaying Key and value pairs
while (itr.hasNext()) {
// Getting Key
String str = itr.next();
/* public V get(Object key): Returns the value to which
* the specified key is mapped, or null if this map
* contains no mapping for the key.
*/
System.out.println("Key: "+str+" & Value: "+files.get(str));
}
if ((files != null) && (!files.isEmpty())) {
UploadFile file_Id = null;
if ((UploadFile) files.get("path_Id") != null) {
file_Id = (UploadFile) files.get("path_Id");
}
upBean = new UploadBean();
upBean.setFolderstore(path_Id);
System.out.println("file_Id: " + /*file_Id.getContentType() + */file_Id.getFileName()/* + file_Id.getFileSize() + file_Id.getClass() + file_Id.getData() + file_Id.getInpuStream()*/);
upBean.store(mrequest, "path_Id");
if (file_Id.getFileName() != null) {
// We get the name of the loaded file
name_Image_Id = file_Id.getFileName();
// Obtain the extension
String extension_Id = FilenameUtils.getExtension(path_Id + name_Image_Id);
// We get the path and the original name

path_Id = path_Id + name_Image_Id;
} else {

}

just set breakpoints and see what is happening. It is not clear from the code but since file address is null it means this piece of code is not getting executedif ((UploadFile) files.get("path_Proof_Of_Address") != null) { file_Address = (UploadFile) files.get("path_Proof_Of_Address"); }print thefiles.get("path_Proof_Of_Address")before thisifblock and if it printsnullthen that means somewhere you are manipulating thefileshastable.
