Are you setting this one?:
hibernate.cache.provider_configuration_file_resource_path=/name_of_configuration_resource
The error might be caused by a missing configuration item.

However, it still does not work. I got the different error:

Mike: How do you turn the "second_level_cache" on? I've added that to the
applicationConext-hibernate.xml, but still got the same error.
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
@HIBERNATE-DIALECT@</prop>
<prop key="hibernate.query.substitutions">true
'Y', false 'N'</prop>
<prop key="
hibernate.cache.use_second_level_cache">true</prop>

You need to set the hibernate property
hibernate.cache.use_second_level_cache to true, and if you want to use
query caches you need to set hibernate.cache.use_query_cache true as well.
Note that for the query cache you will need to enable caching on a query by
query basis.

I try to use ehcache in my appfuse 1.9.4 application.
In applicatonContext-hibernate.xml, <property name="hibernateProperties">

In Status pojo, I added this xdoclet attribute:
[EMAIL PROTECTED] table="status"
[EMAIL PROTECTED] usage="read-write"
In ehcache.xml, besides the defaultCache, I added
<cache
name="com.mycompany.model.Status"
maxElementsInMemory="10"
eternal="false"
timeToIdleSeconds="0"
timeToLiveSeconds="0"
overflowToDisk="true" />
Then I compile and deploy to tomcat, the application failed to start with
very long error stack trace msg. It seems caused by:
Caused by: org.hibernate.cache.NoCachingEnabledException: Second-level
cache is not enabled for usage [hibernate.cache.use_second_level_cache |
hibernate.cache.use_query_cache ]
at org.hibernate.cache.NoCacheProvider.buildCache(
NoCacheProvider.java:21)
at org.hibernate.cache.CacheFactory.createCache(CacheFactory.java
:61)
... 142 more
My question: besides what I have done, what else should I add in order to
enable second-level cache?
