JBossDeveloper

I didn't use any archetypes when Mavenizing my projects. Just right-click on each project and do Configure -> Convert to Maven Project.

Correct.

Make sure you have the RESTEasy Jackson module in your MANIFEST.MF or in jboss-deployment-structure.xml. I'm not sure how you would check that Jackson is marshalling your POJOs. In my projects, using Jackson 2.x and the Jackson JAX-RS integration, I provide Jackson with a specially configured ObjectMapper instance, and I know Jackson is being used for marshalling/unmarshalling because of some configuration options I've set that affect the output.

That looks right to me. The warnings are just telling you that the RESTEasy Jackson provider is a private dependency and that it may be changed or removed without warning in future versions of JBoss. I think it's unlikely it would be removed completely, but I find it more likely that the RESTEasy developers might update their Jackson provider to use Jackson 2.x, which might cause headaches for you later on. This is why I prefer to bundle any non-public dependencies with my EARs, so I have control over the versions of libraries I depend on.

Hello Rich,

Could you pls provide your full pom.xml, showing how to make AS7 produce JSON with jackson-jaxrs-json-provider and Jackson 2.x?

thanks,

Jens

Jens,

These are the artifacts I have in my POM, with the version.jackson property defined as 2.1.1.

{code}
<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-databind</artifactId>
  <version>${version.jackson}</version>
</dependency>
<dependency>
  <groupId>com.fasterxml.jackson.datatype</groupId>
  <artifactId>jackson-datatype-joda</artifactId>
  <version>${version.jackson}</version>
</dependency>
<dependency>
  <groupId>com.fasterxml.jackson.jaxrs</groupId>
  <artifactId>jackson-jaxrs-json-provider</artifactId>
  <version>${version.jackson}</version>
</dependency>
<dependency>
  <groupId>com.fasterxml.jackson.module</groupId>
  <artifactId>jackson-module-afterburner</artifactId>
  <version>${version.jackson}</version>
</dependency>
{code}

Note that if you're using the RESTEasy implementation of JAX-RS that ships with AS7, you also need to disable the Jackson 1.x provider that comes with it. I did this by creating a jboss-deployment-structure.xml in my EAR's /META-INF with this content:

{code}
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
          <sub-deployment name="web-service.war">
                    <exclusions>
                              <module name="org.jboss.resteasy.resteasy-jackson-provider"/>
                    </exclusions>
          </sub-deployment>
</jboss-deployment-structure>
{code}

Thanks alot for your quick response!

I was just composing a response to myselft since I just got it to work (doing /almost/ the same, though without the afterburner dep and using <deployment> element instead of <sub-deployment>).

Still - thanks. Cyclic dependencies in domain now handled....

cheers,

Jens
