Hi i am tying to make simple web application for user registration form using jsp and hibernate When i run my application i am getting following Exeption

Here is My code

How can i remove this Exception and what should i do
Thanks in advance
getting following Exception
type Exception report
messageInternal Server Error
descriptionThe server encountered an internal error that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: org.hibernate.HibernateException: Could not parse configuration: /hiber/hibernate.cfg.xml

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.
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.
If you use Maven, put your hbm.xml file into resource folder under:
/resource/[your package]/hbm.xml
Can you try to give full path for your user.hbm.xml in hibernate.cfg.xml.
<mapping resource="hiber/user.hbm.xml"/>
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.

Normally I should be able to connect to DB but I am getting an error.
Error: - "Exception in thread "main" java.lang.UnsupportedOperationException: The application must supply JDBC connections"
It means I am not able to connect with DB.
I have checked that the database username and password are correct.
ERROR
Main Program
You have typo in conection.url. Should be connection.url.
I'm starting learing how to use IntelliJ, and I'm trying to link my persistence to my datasource.
I've read here on SO how to do that, and now I've binded my persistence to my datasource successfully: I can run queries on database, and i can browse my persistence.
This is the db (MSSQL):
This is the persistence:
And this is the assignment:
The problem is that I'm still getting error on my class, looks like is not able to link to the datasource, and is giving me the error "Cannot resolve column" (not only on ID column, but on all columns):
The application is running fine, so the problem is only related to some wrong intellij configuration, but I can't find where the problem is.
This is my hibernate.cfg.xml (there are more tables, I've left only the one in the example):

Could you check if there are there any blank spaces before in your xml config files?
see: Error: The processing instruction target matching "[xX][mM][lL]" is not allowed
Hope this helps,

I think you are having an issue with connecting to the db properly. Are you sure the user name and password are correct? Or did you have an already a database called datacenter?
Also try changing the doctype as
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
See Can't parse hibernate.cfg.xml while offline
Depending on your hibernate version it might be that hibernate is trying to load the DTD from the internet and that the connection is reset in the meantime.
to run hibernate application offline use 'hibernate-core jar' file it will work..
no need to change your Hibernate configuration file .Avvappa,BEL.
change ur hiber configuration i.e
<hibernate-configuration
xmlns="http://www.hibernate.org/xsd/hibernate-configuration"
xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-configuration hibernate-configuration-4.0.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
----------------------------to as below -------------------------------------
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.5//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
change your Hibernate configuration as follows;
<hibernate-configuration
xmlns="http://www.hibernate.org/xsd/hibernate-configuration"
xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-configuration hibernate-configuration-4.0.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

Try Running the program while your system is connected to Internet
I was facing the same issue. And when i searched for the solution online found this thread regarding the same issue.
I went back and tried running the program again and it worked, the only changes made were connected to Internet Connection. I turned off the connection and again the program was giving the same error as you got.
My guess is the Hibernate configuration file is downloading the DTD from internet, and when it fails to do so it gives error while creating the SessionFactory object.
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
If the configuration file is not parsed, just check for the hibernate version. If it is hibernate 3 the DTD should be from Sourceforge website. if it is the later version the DTD should be
<!DOCTYPE hibernate-configuration SYSTEM
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

Err
Edit1:
Things I tried:
retyping
using dtd
placing xsd to other places
With Hibernate 4.x you should use the same DTD as 3.x:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
as you can see by this bug report, where the deprecation warning was removed.
Also the tutorials for 4.2 version use this, as you can see here.
You forgot to specify DTD.
Try keeping below code in both the xml files and let me know
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
your forgot DTD in hibernate.cfg.xml file
