hi!

there is one mystery left with hibernate:

@hibernate.map

the documentatin (hibernate_reference.pdf) gives some ideas of howto use this kind of relationship type but i would like to see some working samples. xDoclet samples would be very usefull. the xdoclet distribution samples don't show the use of hibernate.map :-(

what types do i need (or can i use) ?

* @hibernate.map
* @hibernate.collection-key column = "rechId"
* @hibernate.collection-index column = "docid" type = "???"
* @hibernate.collection-one-to-many class = "test.ListElement"

what are the posibilities for the key in a HashMap ?
and what can i put in as the HashMap value?

thanks for your help,
blip

the keys can be simple properties, composites, or entities.


the values can be simple properties or entities (not sure about composites as I have not tried that).


This is an awfully open-ended question. Maybe you can give us the situtation you are trying to map, and we can help you figure out how to map it.

thank you for your help. i made some feature/performance and usability comparisons of:

- EJB 2.0 CMP
- Hibernate
- OJB (with JDO RI)

Hibernate is so easy to use (except the poor documentatin for xdoclet and relationships:-) has many many features and the the performance is very good.

and the winner is: HIBERNATE!
