Question

我正在尝试使用Play的Informix数据库！框架应用。我是Informix的新手。

我的Windows机器上安装了Informix 11.70，我正在运行Play 1.1。

在游戏中！您可以像这样指定数据库连接：

db.url=jdbc:informix-sqli://localhost:9088/mydatabase:INFORMIXSERVER=ol_informix1170
db.driver=com.informix.jdbc.IfxDriver
db.user=informix
db.pass=password

但是在运行我的Play时我遇到了异常！应用程式：

An unexpected error occured caused by exception PersistenceException: org.hibernate.TransactionException: JDBC begin failed:

我认为因为我试图在事务中执行我的查询但是我没有指定XA驱动程序。只有com.informix.jdbc.IfxDriver。但是我似乎无法找到用于Informix的XA驱动程序。

如何配置我的游戏！申请使用Informix？

感谢

问题是您没有正确配置Informix。您的数据库未配置为事务日志记录，因此，它不支持事务。不是真正的Hibernate也不是Play！问题。因此，请使用以下内容重新创建表：

CREATE DATABASE mydatabase WITH LOG;
