Upload component

How to upload file in database using upload component? I need to upload document as blob in database and I cant get byte from document that I target, I cant get file path.

Receiving and saving the uploaded document will depend on your server. What are you running on the server? The documentation has links to examples in some popular languages: https://vaadin.com/docs/-/part/elements/vaadin-upload/vaadin-upload-server.html#server-processing

I succeed it. Server wasnt problem.
