Are you sure you have supplyed the right cache provider? It seems as you have provided org.hibernate.hql.ast.ASTQueryTranslatorFactory Which by the look of the name doesn't have much to do with cache.
I dont know much about this, probably less than you, but id try replace that with something else. Like: org.hibernate.cache.EhCacheProvider
This is probably the solution to the other
thread you alos posted.
Do tell how it goes.
