Hii

I am a newbie to Terrcotta. I am trying to integrate EH cache with Teracotta . I am attempting to share a Hibernate 2nd level cache using DSO .However I am getting
errors from Terracotta when hibernate attempts to populate the cache:But I am getting the following error .Please advice me on this.

java.lang.AbstractMethodError: net.sf.ehcache.Cache.setCacheLoader(Lnet/sf/ehcache/loader/CacheLoader;)V

<property name="hibernate.cache.provider_configuration_file_resource_path">ehcache.xml</property>

</session-factory>

</hibernate-configuration>

I am annotating at Hibernate Objects(POJOS) for enabling Cache as shown below:

@Cache (usage=CacheConcurrencyStrategy.READ_WRITE, region="TrialHibernateCache")

Any advice would be helpful.Thanking all in advance.
