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

[emran]

I'm trying to incorporate a class into another class. I have managed to do this in other scenarios, but by the error shown below, I am not getting it now.

O JAXB creates this class "@Embeddable public static class ListRps" within the scope of the class "public class LoteRpsV3 Vo Serializable implements" by command line.

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

In this context, the parse of a XML XML XML for a system object or system object for a XML XML XML It's trivial.

You are merging different AccessType in the same class. Na top level class LoteRpsV3Vo you are using AccessType.PROPERTY (getters notes), so Hibernate expects to find the notes in getters the Nested class ListaRps, as he does not find, he throws that exception.

To solve this, you could add getters and setters in its 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 annotation @Access with the value AccessType.FIELD (indicates that the attributes are noted) in its class ListaRps:

@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;
    }
}

}
