That isn't possible with auto mode. Use the basic mode instead. Then you can bind the input value to an UploadedFile property directly. This only requires disabling Ajax.

E.g.

    ...
    
    ...
    

with

private UploadedFile file; // +getter+setter

public void save() {
    try (InputStream input = file.getInputStream()) {
        // ...
    }
}

The alternative is to migrate to standard JSF component which was introduced in JSF 2.2. Then you can continue using Ajax.

E.g.

    ...
    
    ...
    

with

private Part file; // +getter+setter

public void save() {
    try (InputStream input = file.getInputStream()) {
        // ...
    }
}
