Hello
I'am learning Hibernate and working with Tutorial.
I'am stoped on "Part 2 mapping associations"
My all java file compilled properly: Person.java, Event.java, EvenManager.java, HibernateUtil.java.
I have two hibernate configurationfile Hibernate.cfg.xml, and Event.hbm.xml.
At this point I want save to Database only one entity Event but during running example I receiving exeption "Unable to read XML"
Code:
run:
[java] SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
[java] SLF4J: Defaulting to no-operation (NOP) logger implementation
[java] SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I don't know it is important but I,am used ant instead of maven.
This is Hibernate.cfg.xml
Code:
<?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">

<property name="hbm2ddl.auto">update</property>
<mapping resource="org/hibernate/tutorial/domain/Event.hbm.xml"/>
</session-factory>
</hibernate-configuration>
and Person.hbm.xml
Code:
<hibernate-mapping package="org.hibernate.tutorial.domain">
<class name="Event" table="EVENTS">
<id name="id" column="EVENT_ID">
<generator class="native"/>
</id>
<property name="date" type="timestamp" column="EVENT_DATE"/>
<property name="title"/>
</class>
</hibernate-mapping>
