【问题描述】：
我想在 JBoss 7 中使用 HSQLDB 数据源。 但我也想在 XA 模式下使用数据源。 据我所知，HSQLDB 从 2.2.0 开始支持 XA 事务，我使用的是最新版本的 HSQLDB。我还在HSQLDB jar中找到了对应的类文件：org.hsqldb.jdbc.pool.JDBCXAConnection。
但在启动时，我从 JBoss 收到以下异常：

这是我的数据源配置：
<xa-datasource jndi-name="java:jboss/datasources/LiferayDS" pool-name="LiferayDS" enabled="true" use-ccm="false">
<xa-datasource-property name="URL">
jdbc:hsqldb:file:../../hsql-data/LiferayDS

</xa-datasource>
HSQLDB 中的 XA 类似乎没有提供通用的 XA 配置接口。 我必须如何配置数据源才能在事务模式下使用 HSQLDB？
【问题讨论】：
-
您确定 HSQLDB 支持 XA 事务吗？ atomikos.com/Documentation/NonXaDataSource 另有建议。
-
根据hsqldb.org/doc/guide/running-chapt.html#N100CF，HSQLDB 似乎确实支持 XA 事务。将尝试在文档中查找示例。
-
fossies.org/dox/hsqldb-2.3.4/… 几乎可以肯定地证明 HSQLDB 2.3.4 支持 XA 事务。
-
很遗憾，我在hsqldb.org/doc/2.0/apidocs/org/hsqldb/jdbc/package-summary.html 中找不到课程
org.hsqldb.jdbc.pool.JDBCXADataSource。 -
hsqldb.org/doc/2.0/apidocs/index.html?org/hsqldb/jdbc/… 确实引用了
JDBCXADataSource，它可能是一个内部类。
