java.lang.ExceptionInInitializerError at net.sf.hibernate.examples.quickstart.CatInsert.processRequest(CatInsert.java:59)
I am trying out the very first tutorial example in the reference documentation. It is basically copy and pasted (HibernateUtil is word for word), except for this servlet CatInsert.java. Line 59 is the HibernateUtil.currentSession() line:
