Fwd: JsonJaxbModule for JAX-RS 2.0
Hello Everyone,
Our environment is Tomee web profile with JAX-RS 2.0 libraries added to our
project and api jars on the server.
We are getting a MessageBodyWriter not found when creating a resource that
produces json. The quick searching
I found maven solution however, we do not use maven. Also, I could not find
the binary for JsonJaxbModule anywhere.
We do use web.xml for the project, but not sure which dependency we need to
add and where to find the
dependency. Is this a JEE6 vs 7 issue?
Thanks in Advance,
Nick.

Yeah, I know about that JSON-P standard client api however, wanted
to have the serialization done automatically as is the case for xml.
What I did was, added:
jackson-jaxrs-1.5.4.jar
jackson-core-asl-1.7.0.jar
jackson-mapper-asl-1.7.0.jar
Included "org.codehaus.jackson.jaxrs" to params in web.xml
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.project.example, org.codehaus.jackson.jaxrs</param-value>
</init-param>
And Bob is my uncle! Onto the next problem....
Kind Regards,
Nick.

Ok
Just to try to give the idea of what i was thinking of:
http://www.adam-bien.com/roller/abien/entry/configuring_jax_rs_2_01 for
server side (but jersey has its own scanning for auto discovery on server
side it seems) and json links are
https://jersey.java.net/documentation/latest/modules-and-dependencies.html.
Think to add needed deps (jackson, moxy...depending your choice).
Last note: cxf is not yet 100% jaxrs2 but upgrzding cxf to v2.7 and
replacing jaxrs api in tomee would do something close and more integrated i
think

A single application server version only supports a single Java EE
specification revision. Right now, the only Java EE 7 compliant
application server is GlassFish. You can hack together some things (e.g.
CDI 1.1 + JAX-RS 2.0) on Tomcat 7, but it's only going to go so far.

John thank you so much for your response. What would one expect from a
Tomcat+Jersey 2.0 combination.
Would we have support for JAX-RS 2.0 stuff like:
Resource Context (Request. Response),
Filters (Request. Response)
Interceptors (Writer, Reader),
Async
Context and Dependencies Injection 1.1
I hope these are not to stupid of a question. I always struggle with 1)
Servlet Containers 2.5 vs 3.0
2) Application Servers supporting JEE 6,7,8,9,10,321... The needle that
broke the back you know?
Thanks in Advance,
Nick.

The regular wine example should not be an issue on Tomee if you're using
JAX-RS 1.1/1.0. I have no clue what you might need to do with JAX-RS 2.0
(this type of configuration is really not supportable at this time; you may
want to try regular Tomcat + JAX-RS 2.0).

Hello John,
I was am running the following example:
http://coenraets.org/blog/2011/12/restful-services-with-jquery-and-java-using-jax-rs-and-jersey/
Taking a closer look, his resources "produce" json, but there is no
actually producing of JSON?
Along with MessageBodyWriter what other options do we have?
Thanks in advance,
Nick.

Hi,
If you need to use a MessageBodyWriter, it needs to be annotated @Provider
and implement the interface.
http://jackson.codehaus.org/javadoc/jax-rs/1.0/javax/ws/rs/ext/MessageBodyWriter.html
then it should get picked up automatically.

Romain, i'm sorry I am drawing a blank. Could you please elaborate? I just
have a simple resource:
@GET
@Produces({ MediaType.APPLICATION_JSON})
public List<Wine> findAll() {
System.out.println("findAll");
return dao.findAll();
}
And a web.xml (3.0) pointing to the resource. This is for JAX-RS 2.0 and
maven within TOMEE.
Is there specific example that meets this simple scenario? I did find this
simple example
but could not see any mention of adding a json writer?:
http://tomee.apache.org/examples-trunk/rest-example/README.html
Sorry, a noob right now...
Nick.

Depending your implementation you can need to add the writer for json which
is not on by default. There are a bunch of samples online IIRC

Romain, thank you so much for your quick response!! I really appreciate it.
Not sure really. The error I am getting is:
MessageBodyWriter not found for media type=application/json, type=class
java.util.ArrayList
And all the solutions are related to JAX-RS 1.x and maven. We are using
neither. JAX-RS 2.0
and TOMEE. Any ideas?
Thank you for time.
PS I will post my solution once I actually have one...

Hi
No jaxrs 2 works in servlet 3 containers (if you accept to not get the full
ee integration like ejb) but this class doesnt ring a bell for me, is it a
jersey one?
