Boa noite.
Estou com um erro ao tentar testar um método de um web service que deveria retornar um Json, este é o metodo:
package br.com.telefonica.portalosti.webservice;
import java.util.ArrayList;
import java.util.List;
import javax.inject.Inject;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
@Path("/pessoaResource")
public class PessoaResource {
@GET
@Path("/getAll")
@Produces("application/json")
public List<Pessoa> getAll() {
List<Pessoa> p = new ArrayList<>();
Pessoa pessoa1 = new Pessoa();
pessoa1.setId(1);
pessoa1.setNome("findAll-1");
Pessoa pessoa2 = new Pessoa();
pessoa2.setId(2);
pessoa2.setNome("findAll-2");
Pessoa pessoa3 = new Pessoa();
pessoa3.setId(3);
pessoa3.setNome("findAll-3");
p.add(pessoa1);
p.add(pessoa2);
p.add(pessoa3);
return p;
}
}
Classe Pessoa:
package br.com.telefonica.portalosti.webservice;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class Pessoa {
private Integer id;
private String nome;
public Pessoa() {
super();
// TODO Auto-generated constructor stub
}
public Pessoa(Integer id, String nome) {
super();
this.id = id;
this.nome = nome;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
}
`Ao acessar o método pelo browser recebo o seguinte erro:

Se eu troco a saida para XML (trocando para @Produces(“text/xml”) funciona normalmente…
Alguém tem alguma idéia do problema ?
Obrigado.
