second-level-cache

I have a problem Hibernate does not update 2nd level cache for a collection of items which are subject of cascade removal. Details Assume we have an object Parent which has Parent.myChildren collection of Child objects. Now we have also object Humans with Humans.myAllHumans collection and all Parent and Child objects are in that collection. Now we session.delete(parent) and all the children are cascade removed from the database, but Humans.myAllHumans collection's cache is not updated! It still assumes that cascade deleted objects are in database and we hit following exception while trying to

I add entity to my database and it works fine. But when i retrieve the List, i get the old entity, the new entities i add are not shown until i undeploy the application and redeploy it again. This means are my entities cached by default? But, I haven't made any settings for caching entities in my persistence.xml or any such file. I have even tried calling flush(), refresh() and merge(). But still it shows the old entities only. Am i missing something? Please help me. Welcome to JPA. If you use it, it means you will have huge problems if you update the database outside of JPA unless you know

After configuring EhCache v2.4.5 as the second level cache for hibernate v3.6.7 I get the following error while trying to load all objects of a particular entity using hibernate session. (There is no error for loading the objects for the first time) java.lang.IllegalStateException: The country Cache is not alive. at net.sf.ehcache.Cache.checkStatus(Cache.java:2438) at net.sf.ehcache.Cache.get(Cache.java:1541) at net.sf.ehcache.hibernate.regions.EhcacheTransactionalDataRegion.get(EhcacheTransactionalDataRegion.java:105) at net.sf.ehcache.hibernate.strategy.AbstractReadWriteEhcacheAccessStrategy

I'm trying to decide whether to switch from having Hibernate sprinkled all over to using JPA2.0 and thus be provider portable. 1.Does JPA2.0 support custom user-types? 2.I'm on the verge of implementing Terracotta as a second-level cache to Hibernate with its clustering abilities mainly in mind. I would imagine, but I don't actually know, that JPA2.0 also defines a spec for second-level cache providers. If I'm right, does Terracotta implement it? (If someone could point me to a getting started with Terracotta and JPA I'd appreciate it). Thanks in advance, Ittai Does JPA2.0 support custom user

Has anyone used AppFabric for their second level caching? I know it's to follow the same api as for Velocity ( nhibernate.caches.velocity ) but wanted to know if anyone already had some production experience of using it and if they knew of any particular tips or problems? PhilPursglove The only problem I'm currently aware of is what was covered in this question , that the references in the Velocity cache code are out of date and need updating to the AppFabric v1 release assemblies. I haven't used AppFabric as second level cache but I've used NCache as second level cache for Nhibernate and

I have read other threads on here about this subject but none of the solutions work for me. I tried putting this in my hibernate.cfg.xml: <property name="hibernate.cache.region.factory_class">org.hibernate.cache.spi.EntityRegion</property> I always get this error: could not instantiate RegionFactory [org.hibernate.cache.spi.EntityRegion] I also tried most suggestions from threads on Hibernate websites but no luck. So how do I configure this? MrStack Well, I found the answer (from a Youtube user): Use hibernate-release-4.1.0.Final or later versions. Add jars from lib\optional\ehcache directory
