[JAVA] Mail con allegato ed errore post-jar

[franksisca]

praticamente mi succede questo:

in eclipse, avvio il programma, invio la mail e va tutto been.

esporto un "runnable jar"(per evitare di farlo manualmente), avvio il programma, invio l'email e non và O_O

l'errore è questo:

javax.mail.MessagingException: IOException while sending message;
  nested exception is:
        javax.activation.UnsupportedDataTypeException: no object DCH for MIME ty
pe multipart/mixed;
        boundary="----=_Part_0_25292276.1256028895265"

        ... 4 more

chi mi può aiutare?

forse ho risolto:

MailcapCommandMap mc = (MailcapCommandMap)CommandMap.getDefaultCommandMap();
mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822");
CommandMap.setDefaultCommandMap(mc);
