Hello,

I use hibernate 3.2 rc2 with spring 2.0 RC1 (and jpa), I get a crash (see above) when using ehcache (whatever the ehcache version).

hibernate 3.2 rc1 with ehcache 1.1 or ehcache 1.2 : ok
hibernate 3.2 rc2 with ehcache 1.1 or ehcache 1.2 : crash
hibernate 3.2 rc2 with treecache : ok (I just replace 'org.hibernate.cache.EhCacheProvider' by 'org.hibernate.cache.TreeCacheProvider' for the hibernate.cache.provider_class property).

In the stack trace I can read "Consider using net.sf.ehcache.hibernate.SingletonEhCacheProvider" but this class does not even exist in ehcache.jar.

The ehcache.xml is very simple :

<ehcache>
<defaultCache
maxElementsInMemory="0"
eternal="false"
timeToIdleSeconds="0"
timeToLiveSeconds="0"
overflowToDisk="false"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="0"
/>

<cache name="eg.Category"
maxElementsInMemory="25"
eternal="false"
timeToIdleSeconds="86400"
timeToLiveSeconds="86400"
overflowToDisk="false"
/>
</ehcache>

An idea ? I doubt it commes from spring because everything works with hibernate 3.2 rc1 (and rc2 with treecache).

Thanks,

Out of curiosity, do you have multiple session factories in your application? I have an app with multiple databases (and thus multiple session factories) and I'm seeing this problem as well. I was curious if that might be part of the issue.

It appears as though there is a new release of EHCache (1.2.1) that appears to deal with this. Kind of a pain that this wasn't part of the Hibernate release. I'll test and perhaps put that in JIRA if I can't find it there already...

I misspoke, EHCache 1.2.1 is an *upcoming* maintenance release. You'll have to work from their latest source for now :-(. Also, the definitely seems to be related to having multiple session factories...

My application use multiple session factories and I'm experiencing this problem aswell. I guess I'll have to go back to hibernate 3.1 for now...

use a seperate echache configuration if you have multiple sf's

Everything works fine with ehcache 1.2.2, I do not even need to use SingletonEhCacheProvider. But the diskStore element seems to be required in the xml, even if overflowToDisk is set to false.

I use hibernate 3.2 RC2, hibernate annotation 3.2 RC1, hibernate entitymanager 3.2 RC1 and Spring 2.0 RC3 nightly build

hello,
could anyone tell me how I actually do configure ehcache when I have several session factories and using Hibernate 3.2CR4?

I have an ear-file with two sar-files in it. Each of the sar-files contains an ehcache.xml together with the Hibernate-configuration in jboss-service.xml and all *.hbm.xml files

I still get an exception, though:


Both ehcache.xml files look the same, it is just a copy of ehcache-failsafe.xml. I have also experimented with adding a <cache name=".."..> element to both of the files, but they still give me the "Attempt to restart..." exception.

I have searched the ehcache documentations and also been looking through these forums, but I have found no solution. Also, I would like to stick to the ehcache version distributed with Hibernate (1.2) instead of upgrading to 1.2.1, which I read is a workaround.

my jboss-service.xml:


any help would be highly appreciated!
