Is it possible to get a stream from the FileUpload, like sukh1 asked?
I do not want to upload the whole file. I want to select an excel file from a file dialog, parse it to a certain class which I want to upload to a microservice.
Is this possible without first uploading the whole file?
Can you maybe point me to some documentation/tutorial, because the fileInput and FileUpload docs are not helping with my problem.
