RESTEasy: Could not find writer for content-type application/json type

Question

I have a restful service (post) that consumes (application/json) and produces (application/json). The single param for this service is an annotated java object.

I am using org.jboss.resteasy.client.ClientRequest to send the request to the service. However, I am getting this exception in the client end and the exception:

could not find writer for content-type application/json type.

Does this mean that I am missing some library jars or I have to write my own writer for application/json?

I am using resteasy 2.3.3.Final

Here are various dependencies I added to my pom that I think are probably related:

    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jaxrs</artifactId>
        <version>2.3.3.Final</version>
