Embedded objects containing only one persisted field.

Hi,

I'd like to know 2 simple things about embedded objects containing only one persisted field:

1. Is is possible to access a custom type (marked as embeddable) value via its name instead of the field's name it contains using HQL ?
For instance:

Code:

@Embeddable
public class Text {
public String value;

// ... some not persisted fields

}

Using a HQL query like:

Code:

"from Foo f where f.textField = 'plop'"

Instead of:

Code:

"from Foo f where f.textField.value = 'plop'"

2. Is it possible to ask hibernate to automatically map the embedded Text.value column name to the name of the field using it or even better, to remove the @Embedded ?

For instance:

Code:

@Entity
public class TextUser {
...
Text getMytext() {
 return mytext;
}
}

Instead of:

Code:

@Entity
public class TextUser {
...
@Embedded
@AttributeOverride(name = "value", column = @Column(name = "mytext"))
Text getMytext() {
 return mytext;
}
}

I'm open to any suggestions / advice!
Cheers,
Fred
