jpa mapping of embedded class attribute to a database column

Question

Recently I am working with Java JPA. I am using NetBeans 8.0.2 IDE. EclipseLink implementation of JPA is default to NetBeans. As Database I am using MySql Database.

I want an Embedded Entity With two fields. I want both of them to be saved in database.

Here is my code.

@Basic(optional = false)
@NotNull
@Embedded
private Code code;

@Embeddable
class Code implements Serializable{
@Basic(optional = false)
@NotNull
@Column(name = "code_no")
short codeNo;

@OneToOne(optional = false)
private Language language;

}

I want there will be a code_no SmallInt field and a language_id SmallInt field in the database. But actually it gives me a language_id field with SmallInt and Code field with longblob.

Any help how can I do that? If you need I can give you the full source.

thanks
