Zdravím,
my jsme použili tomahawk:
<h:form enctype="multipart/form-data" id="novinkaForm">
<t:inputFileUpload id="img" accept="image/jpg;image/png;image/bmp"
value="#{novinkaAction.image}">
</h:form>
@Name("novinkaAction")
public class NovinkaAction {
private UploadedFile image;
}
Pokud chcete použít <s:fileUpload /> podívejte se do examples v JBoss a
konkrétně na seamspace. Ten to používá.
Je otázka zda je dobré přistupovat takto přímo k entity. Možná bych si
vytvořil akci, která by měla property typu Photo. A tu bych si v
konstruktoru vytvořil.
Tu akci bych měl @Scope(ScopeType.EVENT).
Snad Vám to pomůže.
Petr
