Hi,
I have an app running under JBoss4.0.5.
I have a quartz task, supposed to do some file parsing and then send a mail with a file
attached. Before implementing this task, i didnt have any Linkage problem with my mail and
activation librairies.
But now when the task launches, i get the following:
javax.ejb.EJBException: com.thalys.opalys.business.MailServiceException: loader
constraints violated when linking javax/activation/DataHandler class
