MIME type problem with a service that returns int and also an error xml message

[Gabriel Guardincerri <gg...@gmail.com>]

Hi,

We are using REST with JAX-RS and proxy clients. 

We have this method

    @GET
    @Path("/{id}/replies/count")
    int getNumberOfReplies(@PathParam("id") long id) throws
RemoteBridgeException, IOException;


The problem seems to be that since the return type is a primitive int, the
MINE type of the method is application/octet-stream. That seems to be true,
since the response is just a number, I mean, not an xml. The problem is that
we are using a text/xml payload to return a error messages. And there is the
conflict. We get a no writer found error when returning the error message.
So I added this

    @Produces("text/xml")

But now the client says the there is no writer when the method is returning
a number. 

So now I added 

    @Produces("text/xml,application/octet-stream")

But it isn't working.

Any ideas about how to solve this? I would prefer to only have text/xml, is
that possible?

Thanks,

Gabriel

I suggest you simply change the method and return type to return a
marshallable object that contains the value you want to produce.  You
can't really overload return type protocols.

Hi

at the moment it is only text/plain that is supported for primitives. 
so only registering a custom writer would convert them into xml.

I'll have to allocate some time later on and probably convert primitives
into something like
<int>3</int> and {"int":3} for JSON...

cheers, Sergey
