May be there was a problem somwhere down instantiating the class that was swallowed up, but I should've seen that. Interestingly enough, I then decided to do away with PGPoolingDataSource all together, and use Tomcat pool instead, and I never seen that exception from getDBDictionaryInstance anymore. Which is strange, considering that JPA shouldn't be able to determine the dictionary directly from a Tomcat pool... > Perhaps someone else can chime in with details? > > One thing you can do is set : > > <property name="openjpa.jdbc.DBDictionary" value="postgres"/> > Thanks! > > > On Sun, Jun 30, 2013 at 2:59 AM, Pawel Veselov <pawel.vese...@gmail.com > >wrote: > > > Hi. > > > > Using OpenJPA 2.1.1, I ran into this problem after I switched to custom > > implementation of the data source.
