Hello,

i have following problem and don't really know, how i could realize this with hibernate!
i have to follow a specification so i couldn't really change the structure of what i'm trying to explain...

I have class JasBean contains several methods over a KeyValueTuple.
one method:


the KeyValueTuple is not part of the specification!
(i thought to handle this with in a one-to-many relationship from JasBean to KeyValueTuple with key and value as properties from KeyValueTuple)

but the Object value could be a String, a JasBean or a not yet defined class !

fe a JasBean could have a KeyValueTuple whose value is another JasBean which has a KeyValueTuple whose value is a.. Foo
Foo extends JasBean and could have a KeyValueTuple whose value is a .. String (that would be the end in this case)


if anybody could give me hints, how to handle this, i would be grateful

Have a read about the one-to-any mapping.

well, my problem is not the one-to-many relation.
is it, how to get the KeyValueTuple persistence, whose property value could be different objects(see above)!

???

a property couldn't be an object, or? musst be an basic type!?
do i have to write my own wrapper classes?

or did i overlooked something ?

ok, i've seen you coul have an object as property,
which should be persistent with two columns for id and classname of the object!
(we try this but in moment there were no database entries and no error messages too)

but what is, when the object is a String, the String has no id.. ?

in moment i would write a hibernate class fe HString with a "String property" and persist the HString instead of the String as Value from the KeyValueTuple !
Don't know if it is the most performand way, but it should work!?

i'm sorry if my thread was too trivial..
