Name and version of the database you are using:mysql 4.1

Hello there! I'm getting this error when using Enums as one of my properties in a persistent class. Is there anything special that should be done?

Here's my class:
@Embeddable
public class Endereco implements BaseEntity {
private static final long serialVersionUID = 6713650151456618035L;
private UFEnum UF;

public enum UFEnum {
MINAS_GERAIS("MG","Minas Gerais");
@SuppressWarnings("unused")
private final String sigla;
private final String descricao;
UFEnum(String sigla, String descricao){
this.sigla = sigla;
this.descricao = descricao;
}
@Override
public String toString() {
return descricao;
}

}

Regards

Vinicius

what database are you using? I'm somewhat successfully using Enum in the EJB3 API against postgresql, so it should work, but from the looks of your stack trace hibernate is trying to get metadata using a method that your JDBC driver doesn't support.
