Hi I followed the wiki user guide to add attachments in my ws invocations/replies using the DataHandler and binding type DOCUMENT. my question is: does this mean i'm using WS-Attachment kind of attachments? or im just defining documents containing base64binary elements? this because ActiveBPEL engine (an open source BPM engine) supports WS-Attachments and does not seem to use the same way Jbossws suggest to handle them.. thanks for any clarification View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4119023#...
