在Oracle Weblogic Server 10.3.6中创建数据源问题错误

我在本地计算机Windows 7中安装了Oracle Weblogic Server . 现在我正在尝试创建一个新的数据源 .

我有一个托管在不同位置的数据库 . 我有连接属性，我可以从我的机器中的SQL_Developer客户端成功执行测试连接 .

数据库连接细节：

> URL : jdbc:oracle:thin:@hostname:port:DB_Name
> 
> Driver Class : oracle.jdbc.xa.client.OracleXADataSource

但是，当我在weblogic服务器中使用相同的连接属性连接到同一个数据库时，它会抛出以下错误：

> Connection test failed.

我的机器中有以下版本：

>    JDK : 1.7
>    Weblogic : 10.3.6
>    ojdbc6.jar (part of weblogic installation, no extra 3rd party driver being used)

请告诉我在weblogic服务器中的数据源配置期间我错过了什么 . 请帮我解决这个问题 .
