Hello All.
I’m having some issues configuring EHCache with Hibernate 3.0 EJB3 annotations. I’m running everything on Tomcat 5.5, Oracle9i and Hibernate 3.0 (I’m hosting the app in Eclipse’s WTP, but the errors occur when launching Tomcat 5.5 standalone as well)

I keep getting this error:

2005-11-14 10:22:48,171 WARN [net.sf.ehcache.config.Configurator] - <No configuration found. Configuring ehcache from ehcache-failsafe.xml found in the classpath: jar:file:/C:/tools/Tomcat-5.5/common/lib/ehcache-1.1.jar!/ehcache-failsafe.xml>
2005-11-14 10:22:48,421 WARN [org.hibernate.cache.EhCacheProvider] - <Could not find configuration [com.mydomain.data.persistence.AssessmentItem]; using defaults.>

ehcache.xml is the root of my classes folder, the same folder as hibernate.cfg.xml. Does anyone have any idea of how to troubleshoot this issue?

Here’s the steps I’ve taken so far:

I can confirm that caching is working by viewing my SQL output and noticing that queries of cached objects are not being executed twice, as expected.

I’ve also successfully validated my ehcache.xml against the schema provided in their documentation. (using http://tools.decisionsoft.com/schemaValidate.html)

I’ve confirmed the file is properly propagating:
Directory of C:\Files\Projects\LearningPath\JavaSource

Here’s my hibernate.cfg.xml
