在 Java 的 AS7（和 JBPM 6.2）中使用的正确事务管理器是什么？
What is the correct Transaction Manager to use in AS7 (and JBPM 6.2) in Java?
我希望有人能在我花几个小时试图弄明白之前回答这个问题！
我正在使用 PoolingDataSource Class 来实例化我的事务管理器。但是，我并没有取得太大的成功。
MySQL 是我的默认数据库。我正在使用：
</p>
<pre><code> PoolingDataSource ds = new PoolingDataSource();
ds.setUniqueName("java:jboss/datasources/jbpmDS");
ds.setClassName("bitronix.tm.resource.jdbc.lrc.LrcXADataSource");
ds.setMaxPoolSize(3);
ds.setAllowLocalTransactions(true);
ds.getDriverProperties().put("user", "root");
ds.getDriverProperties().put("password", "rootpass");
ds.getDriverProperties().put("URL", "jdbc:mysql://localhost:3306/jbpm6");
ds.getDriverProperties().put("driverClassName", "com.mysql.Driver");
ds.init();
当我 运行 代码时，我得到了这个：

这是因为正确的 属性 名称是 "url"（小写）
