Porquê se apagar o DataSource padrão (ExampleDS) no standalone.xml, e usar apenas o que esta configurado no persistence.xml (livrariaDS), a aplicação não funciona?

O que acontece? Esse outro realmente é apenas um que já vem configurado para agilizar a vida.

Sim! mas estranhamente quando utilizo o DataSource assim:

 <datasources>
                <datasource jndi-name="java:/livrariaDS" pool-name="livrariaDS" enabled="true" use-java-context="true">
                    <connection-url>jdbc:mysql://localhost:3306/livraria</connection-url>
                    <driver>com.mysql</driver>
                    <pool>
                        <min-pool-size>10</min-pool-size>
                        <max-pool-size>100</max-pool-size>
                        <prefill>true</prefill>
                    </pool>
                    <security>
                        <user-name>root</user-name>
                        <password>root</password>
                    </security>
                </datasource>
                <drivers>
                    <driver name="com.mysql" module="com.mysql">
                        <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
                    </driver>
                </drivers>
            </datasources>

tenho o seguinte log:

e quando configuro com os dois DataSources:

 <datasources>
                <datasource jndi-name="java:/livrariaDS" pool-name="livrariaDS" enabled="true" use-java-context="true">

                        <password>sa</password>
                    </security>
                </datasource>
                <drivers>
                    <driver name="com.mysql" module="com.mysql">

                    </driver>
                    <driver name="h2" module="com.h2database.h2">
                        <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
                    </driver>
                </drivers>
            </datasources>

Funciona normalmente! pelo que eu entendi, ele precisa do Datasource Default para carregar (ExampleDS), mesmo utilizando outro.
