Java: Spring + Hibernate

[DarthSandr]

Salve a tutti.
Mi è stato passato un progetto server java basato su spring e hibernate; dato che non ho mai avuto modo di lavorare con questi frameworks ho provato a farmi un progettino ex-novo per impratichirmi con l'ABC diquesti due strumenti.
Sto avendo, però, qualche problema con hibernate.
Nel progetto ho un file persistence.xml presente nel path mytestprj/config/hibernate in src/main/resources così definito:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"
    xmlns="http://xmlns.jcp.org/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
        http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="test">
        <mapping-file>/mytestprj/config/hibernate/orm.xml</mapping-file>
        <exclude-unlisted-classes />
        <properties>                    
            <property name="hibernate.connection.datasource"
                value="java:comp/env/jdbc/test" />
            <property name="hibernate.dialect"
                value="org.hibernate.dialect.MySQL5Dialect" /> 
            <!-- Disattivo la rilevazione automatica di classi annotate e file
            di mappatura -->             
            <property name="hibernate.archive.autodetection" value="no" />
            <property name="hibernate.ejb.cfgfile"
                value="/mytestprj/config/hibernate/hibernate.cfg.xml" />                                                  
            <!-- Quote di tutti gli identificatori -->
            <property name="hibernate.globally_quoted_identifiers"
                value="true" />                                            
            <property name="hibernate.hbm2ddl.auto" value="update" />
        </properties>
    </persistence-unit>
</persistence>

orm.xml e hibernate.cfg.xml sono presenti nella stessa cartella di persistence.xml.

Nel file project-servlet.xml in src/main/webapp/WEB-INF ho inserito questo:

<beans:bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor">
        <beans:property name="defaultPersistenceUnitName"
            value="test" />                
    </beans:bean>  
    <beans:bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
            <beans:property name="persistenceXmlLocation" value="classpath:/mytestprj/config/hibernate/persistence.xml" />
            <beans:property name="jpaVendorAdapter">
            <!-- Implementazione JPA di Hibernate -->
                     <beans:bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
            </beans:property>
    </beans:bean>

e su tomcat il datasource è definito nel seguente modo:

<Resource
        name="jdbc/test" type="javax.sql.DataSource"
        maxActive="100" maxIdle="30" maxWait="10000" 
        url="jdbc:mysql://localhost:3306/test"
        driverClassName="com.mysql.jdbc.Driver"
        username="user" password="pssw"
    />

Eseguendo il server ottengo il seguente errore:

javax.servlet.ServletException: Servlet.init() for servlet project threw exception

Qualcuno ha qualche idea in merito?

Ciao, grazie
