I'm trying to use my objects with JAXB annotations for application/json output with my JAX-RS resource. I'm running on JBoss AS7 7.1.1.Final with RestEasy (included within AS). The issue is that I would like to customize my JSON output. I must note that I don't care if I will use Jettison or Jackson, but I was able only make Jettison work (deploy application) without errors. I also would like to stick only with JAXB annotations on my objects if possible.

1) I want to omit "@" within XmlAttribute annotated fields. I found out property how to do it with Jettison, but I don't know how to configure it on JBoss AS7. Didn't find any working ContextResolver or any other example.

2) I would like to have "normal" JSON arrays, e.g.

@XmlRootElement(name = "root")
@XmlAccessorType(XmlAccessType.FIELD)
public class Root { 
    @XmlElementRef(type = Entry.class, required = false)
    // no difference with @XmlElement
    private Set<Entry> entries;
}

serializes into

{"entries":
  {"entry":[{...},{...},{...}]}
}

and I would expect one of those:

{"entries":
  [
   {"entry":{...}},
   {"entry":{...}},
   {"entry":{...}}      
  ]
}

or (omitting XmlRootElement)

{"entries":
  [{...}, {...}]]
}

3) As I noted, I don't care what provider (Jettison/Jackson) will I use but it is hard to find working example how to correctly set maven dependencies for application to be deployable without errors. So far I'm using:

    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jaxrs</artifactId>
        <version>${resteasyVersion}</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jaxb-provider</artifactId>
        <version>${resteasyVersion}</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jettison-provider</artifactId>
        <version>${resteasyVersion}</version>
        <!--<scope>provided</scope>-->
        <exclusions>
            <exclusion>
                <groupId>javax.xml.bind</groupId>
                <artifactId>jaxb-api</artifactId>
            </exclusion>
            <exclusion>
                <groupId>com.sun.xml.bind</groupId>
                <artifactId>jaxb-impl</artifactId>
            </exclusion>
            <exclusion>
                <groupId>javax.xml.stream</groupId>
                <artifactId>stax-api</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

Thanks for all answers
