Weblogic +无状态本地Bean + DataSource注入错误

Question

我有一个像这样的无状态本地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：

我在Webservice（在同一个EAR中）使用此EJB，例如：

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

}

并且，如果我尝试在Webservice的类上获得数据源，它就可以成功运行。

编辑：

另一个考虑因素：使用REMOTE接口可行。但我想将它与Local interface一起使用。

我正在使用Weblogic 10.3.5。我的数据源是在其他应用程序中创建并运行良好的（由JNDI直接获取），那么，我得到的是什么错误？
