Need help with BuildSessionFactory

[kashwini Kulkarni]

Hello,

I am trying an application with struts-hibernate-eclipse.The application was working fine.
My application stopped executing all of the sudden with the following error :

Null Pointer Exception at

_factory = configuration.buildSessionFactory();

I created a sample application and checked for all required files.

struts-config.xml
web.xml
hibernate.cfg.xml

Bean required for hibernate along with its counterpart xml file

Login.java
Login.hbm.xml

But still struggling with the error.

Can anyone please let me know what else I need to check or what can be missing?
I will be thankful if someone can send me a good link explaining in detail about BuildSessionFactory .
