RESTful WebService returning a binary document

[ueland <ha...@hueland.net>]

Hi all,

I'm quite new on web services generally and CXF specially. I want to use CXF
to implement a RESTful webservice which should return binary data directly
in the response with a content type of image/jpeg for example. What I want
to do is to call http://<host>/services/document/<id> and get this document
returned, so that the right application or Save file dialog appears in the
browser. Is this possible using the RESTful libraries with CXF? I think I
could implement this with my own Servlet implementation and setting the
content type and binaray data directly in HttpServletResponse, but I would
like to take advantages of CXF.

I think something like this:

@Get
@HttpResource(location="/document/{id}")
public BinaryData getDocument(String id) {
    ...
}

But this will probably just return a XML document with the encoded binary
data inside?

Any suggestions?


Thanks in advance

Harald

Hi

With JAX-RS you can do

@Get
@Path("/document/{id}")
@ProduceMime("application/octet-stream") // or some other type
public BinaryData getDocument(String id) {
    ...
}

If BinaryData is a custom type then you'd need to create a custom JAX-RS MessagerBodyWriter which will know
how to marshal BinaryData. Alernatively you can just return byte[] or InputStream or Reader. JAX-RS StreamingOutput is also 
supported...

Cheers, Sergey
