Use this in your hibernate.cfg.xml
<?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">
instead of
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC

Eclipse doesn't show correct tables in Hibernate config

I'm making a new project with Hibernate.
I have some problems configure hibernate correctly in my Eclipse environment.

My Eclipse environment only sees the master database instead of my Framework database. Can someone help me with this?

The database was not correctly configured. The user didn't have the correct permissions. After fixing this it works.

I am new to hibernate and having difficulty in understanding what the error is. The jar files used for hibernate are as
hibernate-annotations.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate3.jar
my hibernate.cfg.xml file is as
<?xml version='1.0' encoding='utf-8'?>

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">
----------------------------to as below -------------------------------------
<!DOCTYPE hibernate-configuration PUBLIC

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">

Thanks in advance
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
