Hibernate version: 3.0.2

After reading chapter 5 on caching, I'm pretty confused about what to put in the <cache name=""> in ehcache.xml...

The book doesn't explicitly say anything about it, I can only guess from the example that whatever the full class name is - that should go into cache name="" and that confiruation will apply to all instances of that class..

Am I correct on that one?

All the names involved with cache are region names.
Each part of the cache has its own region name.
By default Hibernate sets region name to entity name (class name).
So then you also set the (region) name in ehcache the same way.
But you could say what ever you want:

In hbm.xml:
<cache usage="..." region="foo.tralala">
In ehcache.xml:
<cache name="foo.tralala">

so if I don't use the region="" parameter, then it's the class name by default?
