CacheException in JBPM

[antonypulicken]

We are using JBPM in our project and we are getting the following errors in our QA environment. Can any one let us know the reason? Appreciate if you can give some inputs at the earliest.

Sounds like a hibernate config issue. Did you customize that? Besides that, I think you have more change on a constructive answer in the hibernate forum.

Looks like somebody enabled ehcache in hibernate.cfg.xml without the necessary setup. Try changing to the following in your hibernate.cfg.xml

<property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>

and see if it helps. Note that hashtablecache is not recommended for production configurations.
