[ http://issues.apache.org/jira/browse/COCOON-1920?page=comments#action_12437778 ] Rice Yeh commented on COCOON-1920: ----------------------------------
After a while of study, I find this issue happens only when I use hibernate with cocoon. If I change the setting of hibernate to use other cache providers other than ehcache, this issue is gone. Then I try to trace the code and observe this issue happens because the diskStorePath used by the hibernate is same as the one for cocoon after hot deployment (before hot deployment, they are not same). So when trying to configure cache manager for cocoon, a same diskStorePath has been taken by hibernate and have a CacheException thrown at line 248 of net.sf.ehcache.CacheManager. I do not know why hibernate uses the same diskStorePath after hot deployment. > net.sf.ehcache.CacheException during hot deployment > --------------------------------------------------- > > Key: COCOON-1920 > URL: http://issues.apache.org/jira/browse/COCOON-1920 > Project: Cocoon > Issue Type: Bug > Components: * Cocoon Core > Affects Versions: 2.2-dev (Current SVN) > Reporter: Rice Yeh > > net.sf.ehcache.CacheException always happens during hot deployment in both > Tomcat or Jetty environments.
