Hello All,
Similar problem occurred while creating Product Promo, when we upload file
for Promo Code Emails then ERROR: java.lang.ClassCastException:
java.nio.HeapByteBuffer occurs.
This file contains list of EmailIds.
This error can be resolved by using following code snippet in file
"PromoServices.java" and function 'importPromoCodeEmailsFromFile".
Promo Code Emails
Reason of error : byte[] wrapper = (byte[]) context.get("uploadedFile");
(Line number : 239)
This line can be replaced by :
ByteBuffer bytebufferwrapper = (ByteBuffer) context.get("uploadedFile");
if (bytebufferwrapper == null) {
return
ServiceUtil.returnError(UtilProperties.getMessage(resource,
"ProductPromoCodeImportUploadedFileNotValid", locale));
}
byte[] wrapper = bytebufferwrapper.array();
Hope , then this error will not occur and file can be uploaded successfully.
Please revert back in case anything wrong or missing.
Regards
Nandani
