Hi,
We're in the process of migrating an application from 3.0.6 to 3.2.1. Our main
interest was to use Optimistic Locking for our many Entity Beans. We have the
application running, using the version strategy for OL, and during most calls to our
backend (which is composed of session fa�ade beans and entity beans), we get errors
such as the one below indicating that a reentrant method call was detected. All the
api's in our session beans have tx required, and we're using read-only method
directives in the entity layer for every non-write method.
Has anyone else seen problems like these? This does not occur with 3.0.6 +
PessimisticLocking
Oh, and we're using commit-option A.
Any help will be greatly appreciated.
Thanks,
