Could you check if there are there any blank spaces before in your xml config files?

Invalid Mapping with Hibernate

I've i run into an exeption while trying to use Hibernate 4.3.x with java on netbeans, the exption is:
Exception in thread "main" java.lang.ExceptionInInitializerError

(the second error says about duplicate mapping, but i dindt mapped twice)
by reading the exeption, it's possible to see that the problem is in the mapping xml of the class Equipe, the XML contains:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

</id>
<property name="nome"/>
<property name="dataNascimento"/>
<property name="email"/>
<property name="enderecoWeb"/>
<property name="fone"/>
</class>
</hibernate-mapping>
And the class:
package model;
import java.util.Date;
public class Equipe {
private int id;
private String nome;
private Date dataNascimento;
private String email;
private String enderecoWeb;
private String fone;
[..]getters and setters[..]

Hole code: https://bitbucket.org/angelorodem/progapl_ii_272278_2015/src

You invoked configuration.configure() twice. Remove the second invocation, or just copy paste the code below:
Configuration configuration = new Configuration();
configuration.configure();
serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
return sessionFactory;

<property name="hibernate.hbm2ddl.auto">update</property>
<mapping class="model.Jogador"/> (remove this)
<mapping resource="model/Equipe.hbm.xml"/>
try this:
<property name="hibernate.hbm2ddl.auto">update</property>
<mapping resource="model/Equipe.hbm.xml"/>

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.

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.

Hibernate beginner

I'm currently trying to learn to use Hibernate to store objects in a database. I've been working through a tutorial at https://netbeans.org/kb/docs/java/hibernate-java-se.html and I'm trying to create an XML file for a very simple class and table. However I'm just totally unable to get it to work and I'm now really getting frustrated. I just can't get it to work.
The database is Postgres 9.2, the class is one I wrote myself and the version of Hibernate is the one that ships with Netbeans 7.3 (3.2, I believe).
The table is as follows:
CREATE TABLE sellable.manufacturers
(
mfr_id serial NOT NULL, -- Manufacturer ID
mfr_name character varying(127) NOT NULL, -- Manufacturer name
CONSTRAINT manufacturers_pkey PRIMARY KEY (mfr_id),
CONSTRAINT manufacturers_mfr_name_key UNIQUE (mfr_name)
);
The class I'm trying to map it to is as follows:
package bikeshop.sellable;
import java.io.Serializable;
public class Manufacturer implements Serializable {
private Integer mfrId = null;
private String mfrName = null;
public Integer getMfrId () {
return this.mfrId;
}
public String getMfrName () {
return this.mfrName;
}
public void setMfrName (String MfrName) {
this.mfrName = MfrName;
}
}
The XML for the Hibernate mapping is:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!-- Generated Aug 21, 2013 7:20:20 PM by Hibernate Tools 3.2.1.GA -->
<hibernate-mapping>
<class name="bikeshop.sellable.Manufacturer" table="manufacturers" schema="sellable">
<comment>Product manufacturers</comment>
<id name="mfrId" type="int">
<column name="mfr_id" />
<generator class="assigned" />
</id>
<property name="mfrName" type="string">
<column name="mfr_name" length="127" not-null="true" unique="true">
<comment>Manufacturer name</comment>
</column>
</property>
</class>
</hibernate-mapping>
And the Hibernate project config is:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<mapping resource="bikeshop/mappings/Sellables.hbm.xml"/>
</session-factory>
</hibernate-configuration>
When I try using the HQL query editor, all I get is the query "select from" displayed, which obviously can't be executed. Attempting to execute it results in an exception.
org.hibernate.exception.SQLGrammarException: could not execute query
Why is this failing to generate a valid SQL query? What am I missing?
EDIT: I've been trying to get this to work, now I'm getting a different error. The HQL query window now displays the message "Unable to retrieve data from the database." and the exception has changed to "org.hibernate.PropertyNotFoundException: Could not find a setter for property mfrId in class bikeshop.sellable.Manufacturer"
The config file has changed to:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<mapping class="bikeshop.sellable.Manufacturer" file="" jar="" package="bikeshop.sellable" resource="bikeshop/mappings/manufacturer.hbm.xml"/>
</session-factory>
</hibernate-configuration>
and the mapping file has changed to:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

</id>
<property name="mfrName" type="string">
<column name="mfr_name" length="127" not-null="true" unique="true">
<comment>Manufacturer name</comment>
</column>
</property>
</class>
</hibernate-mapping>
EDIT 2: As a last ditch attempt I made all the Manufacturer members public and changed the access type to field in the XML.
Now the HQL query works and returns results. But I obviously don't want to take that approach, public fields are a horrible idea!

It seems that the problem is that the HQL editor doesn't get updated classes or metadata all the time when you make changes to the class or its metadata, it also seems that this can happen regardless of whether you use an external XML file or inline annotations.
The only workaround I've found so far is to quit Netbeans and restart it. This makes the HQL query editor update, but is obviously quite annoying.

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

"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">
