Problem getting sessionFactory!?

Question

Java

The bottom line is this:
1. when the program starts, NPE pops up in the line "bookDao.addBook(book);"
Here is the log:
2. following the link indicates that the error pops up in the line "session = HibernateUtil.getSessionFactory().openSession(); "
3. here is the implementation of the method itself "

Answer 1
