Re: REST returning an image?

[Sergey Beryozkin]

Hi

byte[] is supported by a BinaryDataProvider so it should be fine, though I have to admit there's no system test at the moment 
verifying the byte blob can be received fine. There's definitely an os.write((byte[])o) there.

InputStream and File as return types are also supported so can you try, just for a test, see if wrapping the generated byte[] in 
either ByteArrayInputStream or File (with saving byte[] to the disk first) helps.

As far as the byte[] itself is concerned, is there any way to verify that the image is actualy has been generated without errors in 
the first place ?

Cheers, Sergey


I have been using CXF 2.1 to do the JSR-311 thing and its
been working pretty well.
Now I would like to serve up a generated image (JPG/PNG) as the
URL target (actually its a graph created with JFreeChart).

@GET
@Path("graph/{clientId}/image.png")
@ProduceMime("image/png")
public SOMETHING graph(@UriParam("clientId") String id,
                @HttpContext UriInfo info) { ... }

My image is generated in the form of a byte[] array.
I am just wondering if its ok to replace "SOMETHING"
in the above with byte[] or should it be massaged into
some other form?

When I try to dynamically embed into a webpage it doesn't show up.
node.innerHTML = "<p><img src='" + url +"' height='200' width='300' alt='a
graph'/></p>";

If I download explicitly within Firefox I get
The image "http://...../graph/zubegu/image.png"; cannot be displayed
because it contains errors.
If I hit save page as then the image downloads, saves and opens
in an external viewer just fine.

Not sure whats going wrong here.
There seems to be no problems server side.

Thanks
Doug
