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>
