如何在Oracle DB的TomEE服务器上使用Spring和Atomikos事务管理器配置XA事务？

Question

我正在尝试使XA事务在Oracle DB的TomEE服务器上工作。通过Spring配置使用AtomikOS事务管理器。 我使用了atomikos文档https://www.atomikos.com/Documentation/SpringIntegration

中的示例

在服务器启动时，我看到以下异常，因为未创建xa连接池。

数据源配置和Spring bean，如下所示。

<Resource
     name="xads"
         auth="Container"
         type="javax.sql.XADataSource"
         factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
         driverClassName="oracle.jdbc.xa.client.OracleXADataSource"
         url="url"
         username="user"
         password="password"
                 accessToUnderlyingConnectionAllowed="true"
                 maxTotal="10"
                 maxIdle="1"
                 maxWaitMillis="10000"
                 testWhileIdle="true"
                 validationQuery="select 1 from dual"
 />

<bean id="AtomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager" init-method="init" destroy-method="close">
        <property name="forceShutdown" value="false" />
</bean>

<bean id="AtomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp">
        <property name="transactionTimeout" value="300" />
</bean>

<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
        <property name="transactionManager" ref="AtomikosTransactionManager" />
        <property name="userTransaction" ref="AtomikosUserTransaction" />
</bean>

我也尝试改变 driverClassName =“ oracle.jdbc.xa.client.OracleXADataSource” 至 driverClassName =“ oracle.jdbc.OracleDriver”，但是事务实际上并没有加入。

我在https://grokbase.com/t/tomcat/users/117czb4yf0/tomcat-pool-and-xa-datasource看到了类似的帖子，但是建议的博客（http://www.tomcatexpert.com/blog/2010/04/01/configuring-jdbc-pool-high-concurrency）不再有效，它已重定向到https://tomcat.apache.org/

我希望xa数据源可以加入其他事务并进行双向提交。
