Problem: The Hibernate and Derby packages have been added separately. The above problem occurs.

 

 

Cause: When hibernate connects to the database session. begintransation (), it must call connection to connect to the database. hibernate cannot find the derby driver.

 

Solution: add the Derby package to the dependency under the hibernate package. Or put Derby and Hibernian in the same package.
