Olá.
Tenho o seguinte problema…
Tenho duas tabelas
Fornecedor com uma chave primaria unica
@Entity
@Table( name = "ICFORNECED", schema = "SESC" )
public class ICForneced implements Serializable {
private static final long serialVersionUID = -6669959701623327348L;
@Id
private Integer codfor;
... demais atributos
}outra classe Bancos também com uma chave unica
@Entity
@Table( name = "ICBANCO", schema = "SESC" )
public class ICBanco implements Serializable {
private static final long serialVersionUID = 1095406357912480466L;
@Id
private String codbanc;
... demais atributos
}e outra classe para amarrar as contas bancárias deste fornecedor,
esta tem uma chave composta pelo
código do fornecedor
código do banco e
número da conta.
e para mapear esta chave uso uma classe para a pk com @Embeddable
FBNFornecedor
@Entity
@Table( name = "ICFBNFORNECED", schema = "SESC" )
public class ICFBNForneced implements Serializable {
private static final long serialVersionUID = -3764311902338000601L;
@EmbeddedId
private IDICFBNForneced key;
private String agconta;
...
}classe pk
@Embeddable
public class IDICFBNForneced implements Serializable {
private static final long serialVersionUID = 8604389835345528353L;
@Column(name="codfor")
private ICForneced fornecedor;
@Column(name="codbanc")
private ICBanco banco;
private String numconta;
...
}a query de consulta é construida corretamente,
o meu problema é que gera este erro

acredito que a questão esteja em como serializar os atributos do objeto de pk…
desde já agradeço pela ajuda.
