RussianI have a solution derived from what was suggested by @lefloh, I have simply extended the MOXyJsonProvider and added my own padding in the writeTo method. The drawback being its not compatible with Jersey's @JSONP annotation however so the annotation on the resource is now redundant. Any better solutions are welcome.
@Provider
@Produces( { "application/javascript", "application/x-javascript" } )
public class JsonMessageBodyWriter extends MOXyJsonProvider
{
private static final MediaType APPLICATION_JAVASCRIPT = new MediaType( "application", "javascript" );
private static final MediaType APPLICATION_XJAVASCRIPT = new MediaType( "application", "x-javascript" );
@Context
private HttpServletRequest httpRequest;
@Override
protected boolean supportsMediaType( MediaType mediaType )
{
if( mediaType.equals( APPLICATION_JAVASCRIPT ) ||
mediaType.equals( APPLICATION_XJAVASCRIPT ) )
return true;
return false;
}
@Override
public void writeTo( Object object, Class<?> type, Type genericType, Annotation[] annotations, MediaType mediaType,
MultivaluedMap<String, Object> httpHeaders, OutputStream entityStream ) throws IOException, WebApplicationException
{
String callback = httpRequest.getParameter( "callback" );
if( callback == null )
callback = "callback";
entityStream.write( callback.getBytes() );
entityStream.write( "(".getBytes() );
super.writeTo( object, type, genericType, annotations, mediaType, httpHeaders, entityStream );
entityStream.write( ")".getBytes() );
}
}
