      <h:commandButton value="Upload File" /> 
      </h:form> 
    </h:body> 
</html>

Alles nur zu tun versucht, ist erhalten fileUpload Funktion arbeiten, wierd Teil ist, dass javascript und css vorhanden stopft in javax.faces.resources Ordner ist nicht in der Anwendung verwiesen und so gibt es einige seltsame Fehler, die ich bekomme.

andere Sache zu beachten ist, wenn ich eclipse mit icefaces Plugins verwenden dann fileUplaod Funktion funktioniert gut, aber wenn ich versuche, sie ohne Plugins zu bauen und mit nur Standardsatz erforderlich Gläser dann bin ich componenet id Zusammenhang Illegal bekommen.

Irgendwelche Gedanken, Suggestinos?
