Hi,
I'm learning JAXB XmlRootElement for a simple POJO object.
I did successfully run 
System.out.println(service.path("examples").path("unmanaged")
                                .path("todo").accept(MediaType.APPLICATION_XML)
                                .get(String.class));
but not
System.out.println(service.path("examples").path("unmanaged") .path("todo").accept(MediaType.APPLICATION_JSON) .get(Todo.class));
                and the error is.
Exception in thread "main" com.sun.jersey.api.client.UniformInterfaceException: GET http://192.168.56.101:7474/examples/unmanaged/todo returned a response status of 500 Internal Server Error
        at com.sun.jersey.api.client.WebResource.handle(WebResource.java:676)
        at com.sun.jersey.api.client.WebResource.access$200(WebResource.java:74)
        at com.sun.jersey.api.client.WebResource$Builder.get(WebResource.java:503)
        at hk.itags.server.unmanaged.Test.main(Test.java:40)
I copied the examples from a web site which I put here:
package hk.itags.server.unmanaged;


import javax.xml.bind.annotation.XmlRootElement;


@XmlRootElement
// JAX-RS supports an automatic mapping from JAXB annotated class to XML and JSON
// Isn't that cool?
public class Todo {
        private String summary;
        private String description;
        private int number;
        public String getSummary() {
                return summary;
        }
        public void setSummary(String summary) {
                this.summary = summary;
        }
        public void setSummary(int number) {
                this.number = number;
        }
        public int getNumber() {
                return number;
        }
        public String getDescription() {
                return description;
        }
        public void setDescription(String description) {
                this.description = description;
        }
}
and the resource
package hk.itags.server.unmanaged;


import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;


@Path("/todo")
public class TodoResource {
        // This method is called if XMLis request
        @GET
        @Produces( { MediaType.APPLICATION_XML })
        public Todo getXML() {
                Todo todo = new Todo();
                todo.setSummary("This is my 1 todo");
                todo.setDescription("This is my 1 todo");
                todo.setSummary(345);
                return todo;
        }
        
        @GET
        @Produces( { MediaType.APPLICATION_JSON})
        public Todo getJSON() {
                Todo todo = new Todo();
                todo.setSummary("This is my third todo");
                todo.setDescription("This is my third todo");
                todo.setSummary(347);
                return todo;
        }
        
        // This can be used to test the integration with the browser
        @GET
        @Produces( { MediaType.TEXT_XML })
        public Todo getHTML() {
                Todo todo = new Todo();
                todo.setSummary("This is my 2 todo");
                todo.setDescription("This is my 2 todo");
                todo.setSummary(346);
                return todo;
        }


}
