Hi Sergey,
I tell me if it's interesting that CXF provides a servlet status (or
another thing) which list the available provider. As CXF is very modular, I
find it's hard to know which JARs you must to use when you are newbie.
This servlet status could tell this info (JSON provider is not available,
please add Jettison in your classpath for instance).
Thanks for this idea; I think it probably falls into the management
category. The runtime won't really know that JSONProvider is needed
because the user may prefer Jackson, etc, but at least it can list the
registered providers and show what media and Java types they support.
The problem is how to set it up. I'd prefer to have a LogBrowser module
enhanced, there is a lot of potential there, one tab shows (as it is
now) the logs, next one - in/out exchange details, next - other
management info related to WS & RS endpoints, but it would require a
dedicated effort, I'm hoping it will happen sooner rather than later :-)
Cheers, Sergey

Hi
CXF is still very new to me and will be for sometime I guess. My Hello
World service worked just fine when producing XML. If I switch to
@Produces("application/json") I get the message on the client...
"No message body writer has been found for response"
I'm using REST with CXFNonSpringJaxrsServlet and I am sure that the
message
arises because I have not configured JSON support.
(1) First of all which specific jars should I include in my lib? I'm not
a
Maven user so therefore at a disadvantage here. There are a plethora of
likely jar candidates (probably around 10) - things that have 'xjc' and
'jaxb' in their names. I could just include them all of course but that
would be really messy.
Default JSONProvider is in cxf-rt-rs-extensions-providers module, and
you also need to add
<dependency>
<groupId>org.codehaus.**jettison</groupId>
<artifactId>jettison</**artifactId>
<version>1.3.4</version>
</dependency>
(2) Do I need to configure anything in my web.xml? I read somewhere that
there's a need to initialise JSONProvider.
If default provider is used then adding the above dependencies can be
enough, unless you need to configure JSONProvider (ex, to support single
element collections correctly)
(3) I notice from the docs that Jettison (the default provider) has some
issues like array-serialization. I don't really want to have these issues
to contend with myself. Is it easy to use, say, Jackson instead? I
have always found this to be a very good library when I used jaxb
directly.
Sure, please add a Jackon dependency and list a provider in web.xml
Cheers, Sergey
(4) Anything else I need to know?
Thanks for your patience.
