Weblogic+无状态本地Bean+数据源注入错误

我有一个无状态本地Bean，如下所示：

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

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

因此，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：

我在同一个环境中使用来自Web服务的EJB，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，它会成功地工作

编辑：

另一个需要考虑的问题是：使用远程接口可以工作。但是我想把它和本地接口一起使用

我使用的是WebLogic10.3.5。我的数据源是由JNDI创建的，在其他直接获取它的应用程序中运行良好，那么，我得到这个错误是什么呢
