Hi I have Hibernate 3.2 and using java 1.5

How I can chache a n:m (One person have many countries) association with ecache? Is this expedient?

Some facts:

Users can change associations (but rare)
Users can change countries (very rare)

What i must write in:

country.hbm.xml
person.hbm.xml
ehcache.xml
Criteria search..

???

Thank you

You must enable caching for the class and the relations. So there are at least 2 cache tags per class.

Have a look into the documentation.

Yes I enable caching for countries in country.hbm.xml and in the relation many-to-many in person. But I have a n:m table PersonCountry this table have no hbm.xml (i implement it like in the documentation).

I only find caching for 1:n oder for standart cahing entity but not for n:m.
