I'm using Hibernate with this SessionFactory configuration

It works fine until I add one more XML mapping file as follows:
<property name="mappingResources">
<list>
<value>mappings/File1.hbm.xml</value>
<value>mappings/File2.hbm.xml</value>
</list>
</property>
The added mapping "File2.hbm.xml" is not affected at all. I even try to set the class in "File2.hbm.xml" with an invalid name but there is no error shown in Hibernate (When I do that in "File1.hbm.xml", there is exception).
Could you tell me why the mapping "File2.hbm.xml" is not affected? I use Eclipse and Tomcat, does it cache some where. I already tried to clean Tomcat and restart my PC but it does not help.
Thank you in advance!
The problem is Tomcat cached the old config file. After cleaning (Server -> Clean Tomcat Work Directory), the new file takes effect.

New to Hibernate and Spring. So I copied and pasted some configurations online and did the rest myself.
However when I try to start my Jetty server I am getting a Spring error.
Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/data/jpa]
What does this mean?

Replace the url in the beans tag
http://www.springframework.org/schema/data/jpa/spring-jpa.xsd
with
http://www.springframework.org/schema/data/jpa/spring-jpa-1.0.xsd
It seems that the spring-data-jpa-{version}.jar is not included in you project.
Check the library or dependency.
I have been updating the libraries on my application and adding new features
I migrated from Hibernate 3 to 4 I had to do some adjusts on the xml and the ImprovedNamingStrategy stopped working.
I'm sure it's a n issue with the configuration below:

Although there is a column named document_history on the database the application is creating a new one called documentHistory
Even the fact that it's creating a new column is wrong.
<prop key="hibernate.hbm2ddl.auto">validate</prop>
2 things to fix the issue
the property name was wrong, has to be jpaPropertyMap
and hibernate.ejb.naming_strategy was missing the ejb

I try to run a spring project using LocalSessionFactory, I get a null pointer 'cause I've to init the classLoader. Any way I got this exception at the end!
Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'sessionFactoryClassLoader' of bean class [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Bean property 'sessionFactoryClassLoader' is not writable or has an invalid setter method.
Does the parameter type of the setter match the return type of the getter?
any suggestions?
Here is the implementation:

by the way I want to replace com.liferay.portal.kernel.portlet.PortletClassLoaderUtil by another classLoader using springFramework or hibernate Libraries!
sessionFactoryClassLoader is not a property of org.springframework.orm.hibernate3.LocalSessionFactoryBean.
It is available for PortletSessionFactory implementation which extends SessionFactoryImpl.
I have a very strange issue with Spring and Hibernate.
I have everything configured, my database.properties, the hibernate.xml and datasource.xml
as I saw in the tutorials, but connection isn't working.
When I change the connection properties it does not change anything.
My hibernate.xml:
<?xml version="1.0" encoding="UTF-8"?>

My Dao classes are working but not returning any results.
I figured it out.
pl.devell.model was not the correct name of the package to scan.
I currently have Spring configured to use HSQL, but I would like to use MySQL. What needs to change?

Change the following properties:
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://127.0.0.1:3306/schema"/>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
(where 'schema' is your mysql database name, assuming your mysql host is 127.0.0.1)
And add the mysql-connector jar to your classpath.
You'd have to change the driverClass and url properties of the DataSource.
driverClass should be com.mysql.jdbc.Driver
url should be jdbc:mysql://localhost:3306/dbname
A good example of using mysql with java in spring is detailed on the mysql website
The hibernate should be as noted in the answer by ivy.
