FALHA DURANTE O START DO WILDFLY COM O MYSQL

Conseguir start do wildfly com as configuarações no datasource. e modelo. este sameDATASOURCE, mas quando adiciono o projeto no server da erros. Estou com duvida no persistence.xml.

Pra chegar a esse resultado fiz um outro exemplo pois a atividade da aula do curso não conseguir, essas configurações fiz no standalone.xml.

 <datasource jndi-name="java:jboss/datasources/sameDATASOURCE" pool-name="MySQL" enabled="true" use-java-context="true">
                    <connection-url>jdbc:mysql://localhost:3306/samedb</connection-url>
                    <driver>mysql</driver>
                    <security>
                        <user-name>root</user-name>
                        <password>123456</password>
                    </security>
                </datasource>
                <drivers>
            <driver name="mysql" module="com.mysql">
                        <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
                    </driver>
                </drivers>

Persistence.xml

        <properties>

            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>
        </properties>
    </persistence-unit>
</persistence>

Nessa linha o "name " seria de onde , da minha base de dados , datasource, banco.. ?

   <persistence-unit name="casadocodigo-dev" transaction-type="JTA">
