Subject RE: JSON in CXF
Date Tue, 10 Feb 2009 11:24:29 GMT
I think it's a limitation of the underlying JSON library.  Something like:

@XmlRootElement
public class Foo {
  @XmlElementWrapper(name="values")
  @XmlElement(name="value")
  private List<String> values
}

Gives XML like:

<foo>
  <values>
    <value>foo</value>
    <value>bar</value>
  </values>
</foo>

And json like:
{foo: {values: {value: ["foo", "bar"]}}}

Whereas really, if this is an API that you want to publicize, you really want:

{values: ["foo", "bar"]}

Seems like the JSON is generated via JAXB and an XMLStreamWriter, which unfortunately is too
limited to provide real control over the JSON.

Thanks,
Gary

Hi Gary

> JSON via JAXB definitely leaves something to be desired.

Do you reckon it's the limitations of the underlying JSON library that we use (Jettison) or
do you refer to the insufficient number of hooks for our JSON JAXRS reader/writer whiich would
help in producing a better quality JSON ?

Can you post some examples please - I hope it will help us to improve what we have

Thanks, Sergey

Hi guys,

I really like how CXF provides both JSON and XML out of the box.  However, after working with
the JSON serializer a bit, it's obvious that the JAXB annotations translate poorly to JSON,
and that while you have great control over XML via JAXB, JSON via JAXB definitely leaves something
to be desired.

Do you guys know of any jaxb-quality, annotation-driven JSON serializers?

Cheers,
Gary
