You can face this problem during Java Hibernate application development:

Failed to create sessionFactory object.org.hibernate.MappingException: Could not get constructor for org.hibernate.persister.entity.SingleTableEntityPersister
Exception in thread "main" java.lang.NullPointerException


Solution:
The most common mistake is that you have you have
missed any one getXXXX() or setXXXX() methods.

So check again your code and make the missed getXXXX() or setXXXX() methods.
