I am upgrading to hibernate 2.1.3 from 2.0.1 and upgrading from jcs to ehcache.

In section 14.3 of the documentation, the following line is present:

Alternatively (preferrably?), you may specify <class-cache> and <collection-cache> elements in hibernate.cfg.xml.

This is great except that in section 1.1, in the example hibernate.cfg.xml, here is the header for the xml file:

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">

The hibernate-configuration-2.0.dtd does not allow the <class-cache> or <collection-cache> elements. I know that I can put a <cache> element in each of my .hbm.xml mapping files but I prefer putting the cache statements in the hibernate.cfg.xml. Will Hibernate still perform correctly using the old <jcs-cache> and <jcs-collection-cache> elements from hibernate 2.0 while using ehcache as the cache provider? Is this a bug? Am I missing something?

Use the DTD distributed with Hibernate, the PUBLIC DTD is not up to date...

Your XML parser will actually find the DTD in the hibernate2.jar before looking it up on the web.
