Hello,

My problem is the following.
I have a table which contains 2 columns : a key and a label.
In my application there is a screen with a form containing all the couple [key-label] and empty input text to have the possibility to add new couple [key-label].
I would like to know if there is a way to perform automatically the update of the full list.
For example I would like to have a method of the type:
updateList(List oldList,List newList) with:
oldList the old list of couples
newList the new list of couples
And that automatically do the following task:
insert the new couples (those that are in the newlist and not in the oldlist)
update the existing couple
delete the couples that are not in the new list and that were in the old list.


Any help would be really great.
Thanks

I wonder how can u manage to map it and start to talk about this "updateList" method. Do not forget hibernate methods are related to your mappings!!!

If you mapped that Class only, you should call saveOrUpdate for each of that class instance in the list by one and one.


If another class has list of that couples and you mapped both classes, then you can handle this via using <many-to-one association , cascade and unsaved-value properties.
