我有一个这样的无状态本地 Bean：

@Stateless(name="GerencialFacadeBean", mappedName="GerencialFacade")
public class GerencialFacadeBean implements GerencialFacadeBeanLocal {

    @Resource(name="jdbc/adq_sistint", mappedName = "jdbc/adq_sistint")
    private DataSource dataSource;
.. }

所以，当我使用这个bean时，我得到了以下异常：

Caused by: com.bea.core.repackaged.springframework.beans.factory.BeanCreationException: Dependency injection failure: can't find the bean definition about class interface javax.sql.DataSource; nested exception is com.bea.core.repackaged.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [javax.sql.DataSource] is defined: No beans of type javax.sql.DataSource; owner=com.bea.core.repackaged.springframework.context.support.GenericApplicationContext@5d225fc1: display name [com.bea.core.repackaged.springframework.context.support.GenericApplicationContext@5d225fc1]; startup date [Mon Oct 15 16:30:12 BRT 2012]; parent: com.bea.core.repackaged.springframework.context.support.GenericApplicationContext@885e019

重要的：

我从一个 Web 服务（在同一个 EAR）中使用这个 EJB，比如：

.. class MyWebService.. {
 @EJB(name="GerencialFacadeBean", mappedName="GerencialFacade")
 private GerencialFacadeBeanLocal gerencialBean;

}

而且，如果我尝试在 Webservice 的类上获取数据源，它会成功运行。

编辑：

另一个考虑因素：使用 REMOTE 接口它可以工作。但我想将它与本地接口一起使用。

我正在使用 Weblogic 10.3.5。我的数据源在其他应用程序（直接通过 JNDI 获取）中创建并运行良好，那么，我得到这个错误是什么？
