Bom dia,
Estou começando a estudar REST e estou tendo um problema estranho , fiz toda a configuração do web.xml, coloquei as anotações, mas ao tentar acessar o serviço eu recebo “Not Found”, mas consigo acessar o jsp q criei pra fazer um teste.
Resposta:
<html>
<head>
<title>Error</title>
</head>
<body>Not Found</body>
</html>
Rest:
@Path("aluno")
public class AlunoRest {
@GET
@Produces(MediaType.APPLICATION_JSON)
public String busca() {
Dao<Aluno> dao = new Dao<Aluno>(JPAUtil.getEntityManager(), Aluno.class);
Aluno aluno = dao.getById(1);
return aluno.toJson();
}
}
