Jaxb and JPA: class Embeddable Could not determine type for java.util.List

I'm trying to embed a class inside another class. I've already been able to do this in other scenarios, but for the error shown below, I'm not getting it right now.

JAXB creates this class "@Embeddable public static class ListRps" within the scope of the class "public class LoteRpsV3Vo implements Serializable" command line.

These classes were handwritten, but based on these generated classes. If I remove this "@Embeddable public static class ListaRps" class and migrate its "protected List<RpsV3Vo> rps;" attribute to the "public class LoteRpsV3Vo implements Serializable" class I can insert the persistent objects into the database, however, I want to do this because these classes are created by the command line < in> JAXB based on the .XSD files provided by an API .

In this context, parsing an XML for a system object or a system object for an XML is trivial.

You are merging different AccessType into the same class. At the top-level class LoteRpsV3Vo you're using annotated% getters , so Hibernate expects to find annotations in getters from < in> nested class AccessType.PROPERTY , as it does not find, it throws this exception.

To solve this, you could add getters and setters in your class ListaRps and write them down. 

@Entity
@Table(name="LoteRps")
@XmlType(name = "tcLoteRps", propOrder={
    "numeroLote",
    "cnpj",
    "inscricaoMunicipal",
    "quantidadeRps",
    "listaRps"

})
public class LoteRpsV3Vo {

    //Resto da sua classe LoteRpsV3Vo

    @Embeddable
    public static class ListaRps {

        protected List<RpsV3Vo> rps;

        @XmlElement(name = "Rps", required = true)
        @OneToMany(cascade = CascadeType.PERSIST)
        @JoinColumn(name = "loteRpsId")
        public List<RpsV3Vo> getRps() {
            if (rps == null) {
                rps = new ArrayList<>();
            }
            return rps;
        }

        public void setRps(List<RpsV3Vo> rps) {
            this.rps = rps;
        }
    }
}

Or add the annotation ListaRps with the value @Access (indicates that the attributes are annotated) in your AccessType.FIELD class: 

@Entity
@Table(name="LoteRps")
@XmlType(name = "tcLoteRps", propOrder={
    "numeroLote",
    "cnpj",
    "inscricaoMunicipal",
    "quantidadeRps",
    "listaRps"

})
public class LoteRpsV3Vo {

    //Resto da sua classe LoteRpsV3Vo

    @Embeddable
    @Access(AccessType.FIELD)
    public static class ListaRps {

        @XmlElement(name = "Rps", required = true)
        @OneToMany(cascade = CascadeType.PERSIST)
        @JoinColumn(name = "loteRpsId")
        protected List<RpsV3Vo> rps;

        public List<RpsV3Vo> getRps() {
            if (rps == null) {
                rps = new ArrayList<>();
            }
            return rps;
        }
    }
}
