java - EJB 的数据源问题

标签 java jboss ejb

在让我的 EJB 正常工作时遇到了一些问题 - 最终设法让我的 JBoss 服务器与 Netbeans 正常工作，现在我收到以下错误，这似乎与我的数据源有关:

服务器日志如下:

我已经设置了一个数据源，并且它已确认与数据库的连接。

以下技术不确定是否有帮助:

JBoss 6.1.0

Netbeans 7.1.1

Postgres:8.4

任何帮助将不胜感激......

最佳答案

您必须在 JBoss 的文件夹 server/default/deploy 中创建包含数据源 POSTGRES-EJB 配置的 xml，或者在 JBoss 管理控制台的帮助下设置配置。
