Hi Christian,

You are missing the class attribute in your class-cache tags.

I am currently testing with following hbm files for jbpm4. In my hibernate 
config I map these files instead of the standard hbm files that are in JBPM.
To make the JobExecutor not use a query with a :now (timestamp) in it I needed 
to change the DbSessionImpl, to make the query cacheable. I now use 
current_timestamp() in the named query instead of the :now, that will be 
replaced by a timestamp parameter. I also added setCacheable on some of the 
queries that were in the DbSessionImpl.

I am not running your tests, I do however see, the database isn't called as 
many times as before from the JobExecutor. Now the cache is being hit each 
time. Still need to test more though, but this was what I was testing. Using 
jbpm with ehcache does not yet seem to give any problems in our application.

Regards,
Marcel
