Why am i getting hibernate.invalidmappingexception when i try to save an object in database with hibernate..
books.hbm.xml (Inside the resource folder)
<?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">
<hibernate-mapping>
<class name="Books" table="books">
<id name="id">
<generator class="increment"></generator>
</id>
<property name="name"></property>
<property name="author"></property>
<property name="count"></property>
<property name="description"></property>
</class>
</hibernate-mapping>
Hibernate.cfg.xml:
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect"> org.hibernate.dialect.MySQLDialect </property>
<property name="hibernate.connection.driver_class"> com.mysql.jdbc.Driver </property>
<property name="hibernate.connection.url"> jdbc:mysql://localhost/cybage </property>
<property name="hibernate.connection.username"> root </property>
<property name="hibernate.connection.password"> yoga </property>
<mapping resource="Books.hbm.xml"/>
</session-factory>
</hibernate-configuration>
And My project structure is:
I have placed the mapping files BOOKS.hbm.xml in resource folder and the Hibernate.cfg.xml in the META/classes folder
You need to specify a full class name with a package in the books.hbm.xml
<class name="pack.Books" table="books">
....
</class>
You need to have the resources folder in the main folder to have all files in the WEB-INF/classes, after building a war. WEB-INF/classes will be in the class path by default.
You have hibernate.cfg.xml and user.hbm.xml in the classes folder — move all xml from the classes to the resources.
Try to replace this:
<mapping resource="Books.hbm.xml"/>
With:
<mapping resource="resources/Books.hbm.xml"/>
Adding the right path.
You need to provide correct mapping path of hbm file in Hibernate.cfg.xml
so Just replace to
<mapping resource="resources/Books.hbm.xml"/>
Because your hbm file is located in resources folder so you need to provide same path.

This is the cfg file:

The error:
Exception in thread "main" org.hibernate.MappingNotFoundException:
resource: src/Main/Employee.hbm.xml not found

Does anybody know how could I fix this error? I tried different
paths for the hbm xml file , i even tried to move it same place
with the cfg file but it still doesnt work, I am a newbie and dont
really know much about it, I tried to follow some tutorials but I
still cannot manage to make it work.
Thank you!

I have a maven project that I am using with hibernate-core 4.2.3.Final. I have followed the advice provided here:
Where to place hibernate config?
Hibernate Tutorial - Where to put Mapping File?
and the config file in src/main/resources looks like this:
<?xml version = "1.0" encoding = "utf-8"?>
<!DOCTYPE hibernate-configuration SYSTEM
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="connection.url">jdbc:mysql://localhost:3306/justHibernate</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.username">root</property>
<property name="connection.password">12345</property>
<property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>
<mapping resource="com/mycompany/app/model/Movie.hbm.xml" />
</session-factory>
</hibernate-configuration>
while the mapping file is within the package com.mycompany.app.model alongside the Movie class:
<?xml version = "1.0" encoding = "utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<generator class="native"/>
</id>
<property name="title" column="title"/>
<property name="director" column="director"/>
<property name="synopsis" column="synopsis"/>
</class>
</hibernate-mapping>
Exception
The configuration cannot find the mapping file.
INFO: HHH000221: Reading mappings from resource: com/mycompany/app/model/Movie.hbm.xml

Place Movie.hbm.xml under src/main/resources and change path in your config file as follows,
<mapping resource="Movie.hbm.xml" />
Hope this helps.
Good Morning to everyone!
I´m trying to use Hibernate to read an MSAccess database in Java using Eclipse, but it gives me a MappingException
here is my hibernateaccess.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping SYSTEM
"classpath://org/hibernate/hibernate-mapping-3.0.dtd">
<hibernate-mapping>

<property name='connection.password'></property>
<!-- JDBC connection pool (use the built-in) -->
<property name='connection.pool_size'>1000</property>
<property name="hibernate.c3p0.min_size">2</property>
<property name="hibernate.c3p0.max_size">600000</property>
<!-- SQL dialect -->

<!-- Echo all executed SQL to stdout -->
<property name='show_sql'>true</property>
<!-- Mapping files -->
<mapping class="TransporteAccess.hbm.xml" />
</session-factory>
</hibernate-mapping>
and the TransporteAccess.hbm.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping SYSTEM

<hibernate-mapping>
<class name="model.Transporte" table="Transportes">
<property name="transporte" column="TRANSPORTES" type="string"></property>
</class>
</hibernate-mapping>
Which I´m doing wrong???
Thanks a lot!
It is mandatory to have Primary Key in Hibernate, refer
Add Primary key as well,
<id name="id" type="int" column="id">
<generator class="native"/>
</id>
apart from this the hibernateaccess.xml contains some irrelevant tags
Update top lines in hibernateaccess.xml with
<?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>
& change
<mapping class="TransporteAccess.hbm.xml" />
to
<mapping resource="TransporteAccess.hbm.xml" />
I am new to hibernate framework. i made a sample project just to test hibernate. i set up the project. but when i run it i got this error

The Hibernate.cfg.xml file that i put in the main package of the project.

I am using netbeans 7.0
As per DTD, <hibernate-configuration> should have a single <session-factory> but you have declared it twice.
Regarding second error:
org.hibernate.HibernateException: /hibernate.cfg.xml not found
Hibernate looks for the configuration file at the root of the classpath, so check if you have placed this file at root of your classpath.
So once you build your project the hibernate.cfg.xml file should be in classes directory.
Add the following in first line of your xml:
<?xml version="1.0" encoding="UTF-8"?>
I'm trying to set up Hibernate 3.6 in my existing Spring 3 MVC + Spring 3 security project. Nevertheless I keep getting java.lang.ClassNotFoundException in my HibernateUtil class - line with return new Configuration().configure().buildSessionFactory();
My project structure looks like this:
hibernate.cfg.xml:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC

<property name="show_sql">true</property>

DBUser.hbm.xml:

And a relevant part of the pom.xml file:
<!-- Hibernate + MySQL -->
<dependency>

<version>5.1.9</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>3.6.3.Final</version>
</dependency>
EDIT: I've pasted here the stack trace. It was too long to put it right here, because it would make this post confused.
I'd be really glad, if someone could help me with setting up this thing, because I've got no idea, why it can't find that class.
It looks like you are missing the javaassist library. Download the javaassist jar and add it to your classpath.
Your class name should be the package path to the Hibernate POJO in DBUser.hbm.xml, e.g:
user/DBUser
And your mapping resource does not need ./ in the path.
