It looks like you have a typo - should be EhCacheProvider instead of EHCacheProvider:

Rob: Thank you for your reply. I have tried web-inf/ehcache.xml /web-inf/ehcache.xml /WEB-INF/ehcache.xml /WEB-INF/classes/ehcache.xml /ehcache.xml ehcache.xml seems it does not matter where I put it, it can't be found. The same error: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext-hibernate.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: could not instantiate CacheProvider: org.hibernate.cache.EHCacheProvider Caused by: org.hibernate.HibernateException: could not instantiate CacheProvider: org.hibernate.cache.EHCacheProvider Once again, I use appfuse 1.9.4. since ehcache is integrated into appfule. Does anyone have the same problem when using ehcache in appfuse? I don't know what to do now. I need ideas or suggestions. Thanks.

The document mentions it's loaded as a classpath resource, so it would need to be in WEB-INF/classes or in the root of a jar file inside WEB-INF/lib. Just curious why you felt the need to move the file. R. On 1/30/07, Ding, Qin <[EMAIL PROTECTED] > wrote: Rob: thank you for your reply.

Note that for the query cache you will need to enable caching on a query by query basis. Mike. On 1/29/07, Ding, Qin < [EMAIL PROTECTED]> wrote: I try to use ehcache in my appfuse 1.9.4 application.
