I am building a session using :
sf = new Configuration().configure().buildSessionFactory();

It is creating an exception:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645)

Here is my confiq file with some info removed for privacy/security issues:

Does anybody see an issue or is it something different? Thanks for the help
