There's some issue with your ehcache version on your classpath.

Run



and track if you have multiple versions of ehcache in your classpath.

you are correct. Thanks for the tip! I came to the same conclusion last night when examining the jar files. I am, however still getting startup errors. To note, we are using Spring and Hibernate. Hibernate now has it's own built-in ehcache.

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-ehcache</artifactId>
<version>${hibernate.version}</version>
</dependency>

But we are manually including it as well, which I believe is the crux of the problem. My sense is that we should remove the below

<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>${ehcache.version}</version>
<scope>runtime</scope>
</dependency>

Version being 1.6.2 I believe

And use the hibernate-ehcache.

Now I am getting two different stack traces. If I comment out the hibernate-ehcache pom dependency and use the above ehcache.jar 1.6 dependency I get

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.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1509)

Even though I have the below

<prop key="hibernate.cache.use_second_level_cache">true</prop>
<prop key="hibernate.cache.use_query_cache">true</prop>
<prop key="hibernate.cache.provider_class" >net.sf.ehcache.hibernate.EhCacheProvider</prop>

Should this be an ehcache.cache.use_second_level_cache vs. hibernate if not using hibernate-ecache?

And if I try

<prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop> instead of the provider class I get

Which I might expect.

Figured it out! It was a conflict with another usage of ehcache. For now we will wait. Issue is on backlog.

Conflict with the ehcache.jar1.6.2

For me the solution was

<dependency>

<dependency>
<groupId>net.sf.ehcache</groupId>

<version>2.6.9</version>
</dependency>

DAO-context.xml

<prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop>
<!--<prop key="hibernate.cache.provider_class" >net.sf.ehcache.hibernate.EhCacheProvider</prop>-->


All help is much appreciated
