Hello,
We used ehCache in our project, initializing it like this:



Now we involved Hibernate and as it also initializes the CacheManager and does it first, the second initialization does not work anymore throwing:



The ehCache documentation states the the CacheManager's create() method should return the existing singleton instance if one is present, but it does throw an exception instead.

Does anybody know how we can solve this?
We use hibernate 3.2.0 and the ehcache-1.2.jar that comes with it.

Thanks in advance,
Detelin

did you find I solution of your problem ? I got the same things with hibernate 3.2 and ehcache1.2

This is because of the file
ehcache-failsafe.xml which ahs the following entry

<diskStore path="can be one of the following"/>
user.home - User's home directory
user.dir - User's current working directory
java.io.tmpdir - Default temp file path

and usually this error happens if your application server has not released the lock on this folder for creating the ehCahe

make this to user.home and ensure that
eternal="false"
with
diskPersistent="true"

this will make sure that the objects are wriiten once between your re-start your application server.
