relativePath="uploaded"
fileEntryListener="#{fileUpload.uploadFile}"/>
<h:commandButton value="Upload File"/>
</h:form>
</h:body>
</html>
</code>Java-Stück
<code>public void uploadFile(FileEntryEvent event)
{
FileEntry fileEntry = (FileEntry) event.getSource();
FileEntryResults results = fileEntry.getResults();
for (FileEntryResults.FileInfo fileInfo : results.getFiles())
{
if (fileInfo.isSaved())
{
log.debug("########### FILE IS SAVED ########");
}
}
}

Jetzt kann ich im aktuellen Status das Popup-Fenster für die Dateisystemnavigation öffnen und dann die Datei auswählenfileUploadListener sollte getroffen werden, aber im Moment nicht, auch ich bin in der Lage, einige Daten zu bekommen, die ich auf der Serverseite eingestellt habe, so dass die Server-Reise funktioniert, ist nur ein Problem, das ich habefileUploadListener ist nicht getroffen, irgendwelche Vorschläge?
Aktualisieren Ich suche immer noch nach einer Antwort, da ich die Datei nicht erfolgreich auf den Server hochladen konnte.
Update 2 Jetzt bekomme ichContent is not allowed in prolog Ausnahme, nicht sicher, was genau das bedeutet, hier ist der Stacktrace:
<code> ERROR [Faces Servlet] - Servlet.service() for servlet Faces Servlet threw exception: javax.faces.view.facelets.Facele
