[jbossws-users] [JBossWS] - Re: Enabling MTOM-Support at JBossWS client fails

Thank you very much for the replies. In your case the code is working because StatementDO has a single DataHandler field. public final class StatementDO implements Serializable { ... private DataHandler stmtContent; I think the problem is when there is a List of DataHandlers. public final class StatementDO implements Serializable { ... private List stmtContent; I also think you are right and the problem might be taken care of by this: [JBWS-2012] - Attachment support for JAX-WS collections unfortunately it was fixed in version 3.0.2 and I can't move up to that version yet since I am running Jboss 4.0.5 for now.
