Name and version of the database you are using:

mySQL 4.1


If I take the line "<cache usage="read-only" /> " out of WQSample.hbm.xml I don't get this error anymore. Is there something wrong with this entry?

Put the <cache> tag before the <id> tag

But as you can see, in my hibernate.cfg.xml file, the cache provider is set as net.sf.ehcache.hibernate.Provider, yet it's still looking for net/sf/hibernate/cache/CacheProvider. Is there another reference to this cache provider that I need to remove from somewhere?

There is a package refactoring In Hibernate 3.0. Everything from net.sf.hibernate package moved into org.hibernate.

In your hibernate.cfg.xml replace this:
Code:
<property name="hibernate.cache.provider_class">
         net.sf.ehcache.hibernate.Provider !!! INCORRECT in Hibernate 3.0
</property


by this:
Code:
<property name="hibernate.cache.provider_class">
         org.hibernate.cache.EhCacheProvider
</property>
