Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/context/hibernateContext.xml]: Invocation of init method failed; nested exception is java.lang.NullPointerException

[Madhav Kumar]

Yep, Its the problem with creating SessionFactory object. I have given everything right, datasource & connection properties. Still I'm getting this exception. I couldn't find why its happening. Please share me If you have any idea when/why this exception throws.
