Answer 1

check the jar version of hibernate and compare it with DTD version inside hibernate.cfg.xml

it should match basically otherwise it can not resolve the dependencies.

Answer 2

Silly mistake:- your pojo/persistent class has "User.java" name which begins with capital 'U' but the mapping file "user.hbm.xml" begins with small 'u'. Solution:- both names should be same. eg:- "User.java" and "User.hbm.xml". -- Happy Coding.

Answer 3

If you use Maven, put your hbm.xml file into resource folder under:

/resource/[your package]/hbm.xml

Answer 4

Can you try to give full path for your user.hbm.xml in hibernate.cfg.xml.

<mapping resource="hiber/user.hbm.xml"/>

Answer 5

Don't use full path in mapping resource :

<mapping resource="user.hbm.xml"/>

instead of

<mapping resource="hiber/user.hbm.xml"/>

Its work for me hopefully for you.
