Jerome,

Ignore this last question....basically i has an invalid test case.

Hi Jim,

I'm not 100% sure I understand what you exactly want to do:

* For the encoding/client side, your approach is OK.

 * For the decoding/server side, you can directly use the request's entity
as a APPLICATION_XML representation, for example using
req.getEntity().toString().

There is no need to wrap the request entity into a DecodeRepresentation or
even an EncodeRepresentation as this is already done by the
"decoderService".

If you want to encoded representation (GZIP), you have to turn off the
"decoderService" on your application.

 * Note that in the future, we'd like to add a "encoderService":

Hey Jerome,

I want the decoder service enabled. I guess my question is whether i am doing something wrong.

On the client I do something like this

Representation rep = new EncodeRepresentation(Encoding.GZIP,    

new StringRepresentation(getXStream().toXML(records), MediaType.APPLICATION_XML));

and on the server side i need to do something like this to retrieve the original StringRepresentation.

(EncodeRepresentation)((DecodeRepresentation)entity).getWrappe

dRepresentation()).getWrappedRepresentation();

So the StringRepresentation is wrapped inside the EncodeRepresentation which is subsequently wrapped inside a DecodeRepresentation.

Can you confirm

Hi Jim,

The Application.decoderService is already able to

automatically decode

incoming compressed representations. If you prefer to disable this
behavior, just do:

myApp.getDecoderService().setEnabled(false);

before starting the application.

Best,
Jerome


2007/10/9, Jim Alateras <[EMAIL PROTECTED]>:

Okay this is my problem. I was assuming that i would get

the wrapped

representation once it hits my resource by i get the
DecodeRepresentation instance instead.

Can I configure my Application so that the wrapped

representation is

sent to my resource class rather than the DecodeRepresentation?

This how i encode the rep

new EncodeRepresentation(Encoding.GZIP, new

StringRepresentation(getXStream().toXML(records),
MediaType.APPLICATION_XML));

but i end up getting the following error on the server.
