我希望有人能在我花费数小时试图解决之前回答这个问题！
我正在使用PoolingDataSource类来实例化我的事务管理器。但是，我没有取得多大成功。
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();
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();
我运行代码时得到这个：

答案 0 :(得分：0)
引起：bitronix.tm.utils.PropertyException：没有可写属性 'URL'......
这是因为正确的属性名称是“url”（小写）
