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
