How to serialize JSON java.util.Date variable to ISO-8601 format date string in WildFly?

Question

I am using WildFly 8.0.0 Final. The rest WebService implementation is RestEasy. According to the WildFly/Jboss documentation, I have added jboss-deployment-structure.xml to use Jackson2.2.* provider.

<jboss-deployment-structure>
    <deployment>
        <exclusions>
           <module name="org.jboss.resteasy.resteasy-jackson-provider"/>
        </exclusions>
        <dependencies>
            <module name="org.jboss.resteasy.resteasy-jackson2-provider" services="import"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

Right now, my problem is that all the java.util.Date variables are not serialize as ISO-8601 format. I have seen this post Wildfly using the Jackson provider instead of Jettison , but it's using jackson-provider-1.

Is there any configuration that can make all date variables be formatted as ISO-8601?

I don't want to add any outside dependencies. Only using WildFly provided is the best choice. I have add the below dependency into my pom.xml file. My code is at https://github.com/evil850209/javaee7-samples

<dependency>
    <groupId>com.fasterxml.jackson.jaxrs</groupId>
    <artifactId>jackson-jaxrs-json-provider</artifactId>
    <version>2.3.0</version>
    <scope>provided</scope>
</dependency>

I have done the something as this post (Wildfly using the Jackson provider instead of Jettison) mentioned. Now I got new error:

I have changed my jboss-deployment-structure.xml, and I put it under WEB-INF folder.

<?xml version="1.0" ?>
<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="org.jboss.resteasy.resteasy-jackson-provider" />
        </exclusions>
        <dependencies>
            <module name="org.jboss.resteasy.resteasy-jackson2-provider" services="import" />
            <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" />
        </dependencies>
    </deployment>
</jboss-deployment-structure>

My JacksonConfig class is like:

import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;

@Provider
@Produces(MediaType.APPLICATION_JSON)
public class JacksonConfig implements ContextResolver<ObjectMapper> {

    private final ObjectMapper objectMapper;

    public JacksonConfig() {
        objectMapper = new ObjectMapper();
        objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
    }

    @Override
    public ObjectMapper getContext(Class<?> type) {
        return objectMapper;
    }

}

It seems like the jboss-deployment-structure.xml is not import the jackson2 class to my WildFly server. Is there anyone how to resolve this issue?
