After insertion,there is no data exists in the USERS table.
Any help is appreciated.

Hibernate version:

<class name="dms.modual.User" table="USERS">

</id>
<property name="rootFolderId" type="java.lang.Integer" column="ROOT_FOLDER_ID"/>

</class>
</hibernate-mapping>

Code between sessionFactory.openSession() and session.close():
UserForm userForm=(UserForm)form;
User user=new User();
user.setUserName(userForm.getUserName());
user.setPassword(userForm.getPassword1());
user.setRootDeptId(new Integer(userForm.getRootDeptId()));
user.setRootFolderId(new Integer(userForm.getRootFolderId()));
user.setUserRank(new Integer(userForm.getUserRank()));
Session dbSession=appSessionFactory.currentSession();
Transaction tx=null;
try{
tx=dbSession.beginTransaction();
dbSession.save(user);
}
catch(Exception ex){
if(tx != null) {
tx.rollback();
}
ex.printStackTrace();
}
finally{
appSessionFactory.closeSession();
}
