[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - NoClassDefFoundError: Hibernate 3.2.3.GA and JBossCache 2.0.

[joereger]

I'm having trouble getting Hibernate to work with JBossCache 2.0.  I'm running on Tomcat 5.5.  Could be a jar problem of some sort on my side but I was cautious about adding/updating to jbosscache 2.0.

Hibernate 3.2.3.ga
JBossCache 2.0.0.GA
JGroups 2.6.0-beta-1

I get this error when HibernateUtil starts up:
java.lang.NoClassDefFoundError: org/jboss/cache/TransactionManagerLookup
  | 	at java.lang.Class.getDeclaredConstructors0(Native Method)
  | 	at java.lang.Class.privateGetDeclaredConstructors(Unknown Source)
  | 	at java.lang.Class.getConstructor0(Unknown Source)
  | 	at java.lang.Class.newInstance0(Unknown Source)
  | 	at java.lang.Class.newInstance(Unknown Source)
  | 	at org.hibernate.cfg.SettingsFactory.createCacheProvider(SettingsFactory.java:371)
  | 	at org.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java:241)
  | 	at org.hibernate.cfg.Configuration.buildSettings(Configuration.java:2009)

It looks like SettingsFactory.createCacheProvider() is looking for a hard-coded "org.jboss.cache.TransactionManagerLookup" which in JBossCache 2.0 should probably be "org.jboss.cache.transaction.GenericTransactionManagerLookup". I'm configuring Hibernate programatically:
conf.setProperty("hibernate.cache.use_second_level_cache", "true");
  | conf.setProperty("hibernate.cache.provider_class", "org.hibernate.cache.TreeCacheProvider");
  | conf.setProperty("hibernate.cache.use_structured_entries", "true");
  | conf.setProperty("hibernate.cache.use_query_cache", "true");
  | conf.setProperty("hibernate.cache.usage", "transactional");

I've searched my entire codebase and never use "TransactionManagerLookup".

Question: Am I using the correct value for "hibernate.cache.provider_class" in my programmatic Hibernate configuration?

Let me know if there's more info I can provide.  Thanks for the help,

Joe

The top of my treecache.xml looks like:
<mbean code="org.jboss.cache.jmx.CacheJmxWrapper" name="jboss.cache:service=TreeCache">
  |         <depends>jboss:service=Naming</depends>
  |         <depends>jboss:service=TransactionManager</depends>
  |         <attribute name="TransactionManagerLookupClass">org.jboss.cache.transaction.GenericTransactionManagerLookup</attribute>
