Basically 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 1.1

Hi Mark, actually I had the same problem, I did solve it by adding jettison provider for application/json mime type. I don't know whether resteasy 1.1 containts jettison provider but version 1.2 does. Also if you are using jdk 1.6 you must exclude javax.xml.stream:stax-api jar file, otherwise you will have a problem.

Here is the example:

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;


@XmlRootElement(name="account")
public class Account {

    private Long id;
    private String accountNo;


    public Account(){}
    public Account(String no)   {
        accountNo=no;
    }


    @Id
    @XmlElement
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }

    @XmlElement
    public String getAccountNo() {
        return accountNo;
    }
    public void setAccountNo(String a) {
        accountNo = a;
    }

}

and JAXB class:

import java.util.ArrayList;
import java.util.List;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;


    @Path("/account")
    public class AccountService {


        @GET
        @Path("/{accountNo}")
        @Produces("application/json")
        public Account getAccount(@PathParam("accountNo") String accountNo) {
                   return new Account(accountNo);
        }

    }

That's all, have a nice day!
