Hi,
Are you including the JavaMail API in the war? And there might be a
version conflict between the one in the war and one distributed with
JBoss? If so you might try to remove the one in the war it.
Alternatively you can upgrade Jersey because later versions (i cannot
recall which version specifically) changed from using JavaMail to
MimePull.
