Many Thanks, I have been studying the echoAttachments sample. Unfortunately I want to adapt the use of attachments to work with my existing assets. I currently have an operation that has a returnType="CustomBean" this "CustomBean" has a property that accesses a byte[]. I would like to be able to maintain the same service signature but alter my "CustomBean" to access a DataHandler instead of the byte[].
Are attachments only supported as outlined in the echoAttachments sample where the service defines a returnType="DataHandler" where the DataHandler must be the root of the service response or request definition? Would a custom Serializer/Deserializer support this functionality?
