Hi,
When I tried to load objects using Hibernate then I am getting below exception. Strange part is, error comes infrequently.
error goes when i restart the server. I don't understand whether it's problem from Websphere or hibernate. Inside my DAO implementation method, I closing all hibernate sessions properly. Also I tried downloading latest Oracle JDBC Drvier, But error still persists.
We are not using any EJB also. It's simple POJO. It seems error is due to sharable connection.
can somebody help to resolve below error?
Code:
I J2CA0086W: Shareable connection MCWrapper id 2f2a2f2a Managed connection WSRdbManagedConnectionImpl@52505250 State:STATE_TRAN_WRAPPER_INUSE
from resource jdbc/benefitbuilderDS was used within a local transaction containment boundary.
