java - 在 Java 的 AS7(和 JBPM 6.2)中使用的正确事务管理器是什么？

Question

我希望有人能在我花几个小时试图弄清楚之前回答这个问题!

我正在使用 PoolingDataSource 类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:

 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:

Caused by: bitronix.tm.utils.PropertyException: no writeable property 'URL' ...

这是因为正确的属性名称是“url”(小写)
