Java WildFly 8.1不接受在web.xml上配置的数据源

我有一个JAVA EE 7项目，它使用WildFly 9.0.2最终版本作为应用程序服务器，并且我已经使用web.xml上的标记配置了数据源，它工作得很好，但是当我使用WildFly 8.1时，它就不再工作了

web.xml的相关部分：

<!-- Mysql datasource configuration -->

<data-source>
    <name>java:app/datasources/MysqlAuronDS</name>
    <class-name>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</class-name>
    <url>jdbc:mysql://localhost:3306/auron</url>
    <user>root</user>
    <password>123456</password>
    <transactional>true</transactional>
    <isolation-level>TRANSACTION_READ_COMMITTED</isolation-level>
    <initial-pool-size>2</initial-pool-size>
    <max-pool-size>100</max-pool-size>
    <min-pool-size>10</min-pool-size>
    <max-statements>0</max-statements>
</data-source>
<!-- Postgres datasource configuration -->
<data-source>
    <name>java:app/datasources/PostgresAuronDS</name>
    <class-name>org.postgresql.xa.PGXADataSource</class-name>
    <url>jdbc:postgresql://localhost:5432/auron</url>
    <user>postgres</user>
    <password>123456</password>
    <transactional>true</transactional>
    <isolation-level>TRANSACTION_READ_COMMITTED</isolation-level>
    <initial-pool-size>2</initial-pool-size>
    <max-pool-size>100</max-pool-size>
    <min-pool-size>10</min-pool-size>
    <max-statements>0</max-statements>
</data-source>

请注意，我已经配置了两个数据源，可以在持久化单元上更改数据源。还请注意，所需的驱动程序由maven处理。

从安全角度来看，将MySQL根用户配置为数据源是一个坏主意。除此之外：您应该添加预期的和实际的行为以及收到的错误消息。此外，确保驱动程序安装正确（我不熟悉Wildfly，但在JBoss 7中，它们必须安装到modules文件夹中或进行部署-请检查）。该数据源仅用于测试，只是编辑了带有错误消息的问题，谢谢@try-catch-finnaly。这些错误消息似乎并不表示任何有关数据源问题的信息。如何部署应用程序？不要将数据源保存在web.xml中，而应该在

$WILDFLY_HOME/standalone/conf/standalone.xml

中配置它。Everv0id我知道WILDFLY服务器的功能，正如我在前面的评论中所说，它工作正常，但是我需要在项目上而不是服务器上配置数据源，谢谢大家的关注。
