RESTFUL Web service returning Image

[tutu <tu...@gmail.com>]

Hi,

I'm trying to create a REST web service that returns an image. Is there an
easy way to do that?

I already hava REST web services that return json:
my xml file:
<jaxrs:server id="restServices" address="/">
	<jaxrs:serviceBeans>
		<ref bean="serviceImpl" />
	</jaxrs:serviceBeans>
	<jaxrs:extensionMappings>
		<entry key="json" value="application/json" />
	</jaxrs:extensionMappings>
</jaxrs:server>

and in my class:

@Produces("application/json" )
public class ServiceImpl {

        @GET
	@Path("/getCategories")
	public Categories getCategories() {
        ...
        }
}

Is there a way to have any web service that returns an image instead of
json?

Regards,

Tugdual

Hi

Perhaps you might want to have a method which returns say java awt image and
have @Produces("image/gif") (or whatever the right media type is) on that
method ? There's no default support for serializing Images (perhaps we
should do some work here) so you'll also need to register a message body
writer. Simpler option would likely be returning JAX-RS StreamingOutput
implementation which will help the runtime to write it efficiently... You
can also return File/byte[]/InputStream representing this image

cheers, Sergey
