Transfer pliku z wykorzystaniem RMIIO

Witam,

Próbuje przesłać plik z klienta na serwer. Klient komunikuje się z serwerem przy pomocy interfejsu zdalnego komponentu EJB. Jeżeli chodzi o serwer - to używam Wildfly. Do przesłania pliku wykorzystuje bibliotekę RMIIO, jednakże w czasie próby wysłania pliku otrzymuje następujący błąd od serwera:


13:00:12,548 ERROR [org.jboss.as.ejb3] (EJB default - 2) javax.ejb.EJBTransactionRolledbackException: Unexpected Error

Z błędu wynikałoby, że problem tkwi w tej linijce kodu: inputStream = RemoteInputStreamClient.wrap(file);(poniżej znajduje się całość kodu).
Kolejną rzeczą, która mi spędza sen z powiek jest brak wiedzy na temat przyczyny tej linijki błędu: Caused by: org.jboss.modules.ModuleLoadError: org.apache.commons.logging.LogFactory:main.

Autor biblioteki w FAQ wspomina, że oprócz jej samej wymagane są dodatkowe zależności: DEPENDENCIES. Z pominięciem test, wszystkie zależności dodałem do plików pom.xml zarówno klienta jak i serwera (oznaczyłem te, które dotyczą rmiio):

Zawartość pliku jboss-deployment-structure.xml znajdującego się po stronie serwera:

Bez powyższego fragmentu kodu, w czasie próby wysłania pliku otrzymywałem wyjątek java.lang.ClassNotFoundException: com.healthmarketscience.rmiio.RemoteInputStream.

Czy ktoś miał do czynienia z tą biblioteką i serwerem Wildfly/JBoss (lub też nie, ale domyśla się w czym tkwi problem) i jest w stanie mi powiedzieć co powinienem zrobić, żeby pozbyć się tego błędu i doprowadzić do przesłania pliku?

Nie jestem pewien gdzie dokładnie tkwi problem. Wygląda to tak, jakby serwerowi Wildfly coś brakowało, być może brakuje mi jakiś zależności w pliku jboss-deployment-structure.xml, ale próbowałem już na różne sposoby i bez skutku.
