So

, wenn ich ein Bild geben werde, und klicken Sie anschließend auf dann ich bin immer einen Fehler wie diese

Auch hinzugefügt i "commons-logging" in pom.xml und "Bean" von "multipartResolver" in momcab- servlet.xml läuft nicht einmal in meinem Tomcat. so idk, wo mein Fehler auftritt. Jede Hilfe in diesem wird geschätzt. Ich danke Ihnen
