Question

I\'ve been writing a little application that will let people upload & download files to me. I\'ve added a web service to this applciation to provide the upload/download fun

Answer 1

Yes, it is possible with Metro. See the Large Attachments example, which looks like it does what you want.

JAX-WS RI provides support for sending and receiving large attachments in a streaming fashion.

• Use MTOM and DataHandler in the programming model.
• Cast the DataHandler to StreamingDataHandler and use its methods.
• Make sure you call StreamingDataHandler.close() and also close the StreamingDataHandler.readOnce() stream.
• Enable HTTP chunking on the client-side.
