Question

出于某种原因，我应该使用旧的EJB容器GlassFish 2.1.1。（通过Java EE 5和EJB 3.0认证）。项目结构如下：

MDB：

@MessageDriven(
   mappedName = "jms/Queue",
   activationConfig = {
      @ActivationConfigProperty(propertyName = "destinationType", 
                                propertyValue = "javax.jms.Queue")    
})
public class TriggerMBean implements MessageListener {
     @EJB
     private TriggerProcessor triggerService; 

     public void onMessage(Message message) {
          //.......
          triggerService.process();
          //.......
     }
}

TriggerProcessor：

@Stateless
public class TriggerProcessor {
    public void proceess() {
        //....
    }
}

我没有创建部署描述符。据我所知，如果我使用从3.0开始的注释和EJB版本

，则没有必要

部署时，异常如下：

我尝试使用private TriggerProcessor triggerService;和@EJB(beanName="TriggerProcessor") public class TriggerProcessor {..注释@Stateless(name="TriggerProcessor")，但没有帮助。

实际上，这完全适用于最新的Glassfish 3.1。但正如我所说，我应该使用GF 2.1.1。

任何帮助表示赞赏！

由于GlassFish 2不支持EJB 3.1，因此无法正常工作。 TriggerProcessor ony提供了无接口视图，因为它没有实现任何接口。您必须提供TriggerProcessor符合EJB 3.0的接口。

只有EJB 3.1支持无接口视图。请参阅JSR 318规范的http://docs.oracle.com/cd/E19776-01/820-4496/beahm/index.html和 1.2 EJB 3.1中的新内容

章节。

EJB依赖关系未在GlassFish 2.1上正确连接（注入）
