Hi,
I am using jboss cache as my 2nd level caching policy.
My persistence.xml has the following configuration:
<property name="hibernate.cache.use_second_level_cache" value="true" />
<property name="hibernate.cache.provider_class" value = "org.hibernate.cache.TreeCacheProvider"/>
<!-- JBoss Cache configuration file name -->
<property name="hibernate.cache.provider_configuration_file_resource_path" value="absolute-path-to/cache-config.xml" />

But everytime I run my application, I get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/jboss/cache/TransactionManagerLookup

What could be the problem? I have given jbosscache-core.jar and jgroups.jar as part of the classpath library. Is tehre something else which I am missing?

use jboss-cache.jar (org/jboss/cache/TransactionManagerLookup)
instead of jbosscache-core.jar (org/jboss/cache/transaction/TransactionManagerLookup)

Thanks ferozz for your suggestion. I made the change, but I am still getting the same error:
