Looking at that exception anonymous wrote : | java] org.jboss.ws.core.jaxrpc.binding.BindingException: Mime type application/octet not allowed for parameter DataHandler_4 allowed types are [text/xml] | i assume that you are not using MTOM at all. That particular error occurs when sending an SWA attachment where the mime types of the datahandler doesn't match the WSDL. I would suggest to first make sure that mtom is enabled for your endpoint: http://jbws.dyndns.org/mediawiki/index.php/JAX-WS_User_Guide#MTOM.2FXOP This would then already solve the later problem i guess.
