DataHandler and StreamDataHandler

Hi,

i tried to create a web service provider which allow the consumers to upload attachments. I implement a MTOM sample, with DataHandler, StreamHandler. But when i try to save the provider, a error message appears, that this data types are not supported.

I know that attachments could be uploaded, using a byte array, but whats a but large datas?

Is there a other way to upload files in a streaming fashion?

thanks
