Problem when updating an image path (Java - MySQL) - Skip the "\"

I am updating a record in a database, when loading the user I am placing the path of your photo in a hidden TextField, but when updating the record, you are saving the path but without the "\" (see image) ).

For example, save the path like this: C: UserssantiPictureslogoapp.png

This means that you can no longer access the image again, because the route is damaged.

Does anyone know why I omit it, or what can I do? Thank you very much.
