Pessoal, podem me ajudar na configuração deu um projeto Spring com JPA e Hibernate, por favor?

Comecei um projeto do zero, para treinar esta parte da persistência, e estou com erro ao tentar subir o TomCat.

Erro

O seu persistence.xml está em src/main/resources/META-INF ?

No seu entityManagerFactory, coloque os packagesToScan e persistenceUnitName:

<property name="packagesToScan">
            <list>
                <value>br.com.moreira.peso</value>
            </list>
        </property>

<property name="persistenceUnitName" value="peso" />

O persistence.xml está em eclipse-workspace-moreira\peso\WebContent\META-INF.

Alterei o entityManagerFactory conforme abaixo:

    <!-- Gerenciamento de JPA pelo Spring -->
    <bean id="entityManagerFactory"
        class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="mysqlDataSource" />
        <property name="jpaVendorAdapter">
            <bean
                class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
        </property>
        <property name="packagesToScan">
            <list>
                <value>br.com.moreira.peso</value>
            </list>
        </property>

        <property name="persistenceUnitName" value="peso" />
    </bean>

O erro mudou para
