java - 非法参数异常 : Invalid ejb jar: it contains zero ejb

Question

我似乎对这个问题有很多疑问，但我仍然无法解决它，我知道当尝试部署没有任何用 @Stateless、@Stateful、@MessageDriven 或 @Singleton 注释的类的 ejb 模块时会抛出此异常。但这不是我的情况，我有几个类注释如下:

@Stateless
@Remote(TestServiceInterface.class)
public class TestService extends TestSuperclass implements TestServiceInterface<Test>, Serializable{
}

这是界面:

public interface TestServiceInterface<T> extends AnotherInterface<T>{
}

我的所有接口(interface)都位于另一个项目中，该项目的 jar 作为 lib 添加到我的 ejb 模块中。

当我尝试部署时，出现以下异常:

1. A valid ejb jar requires at least one session, entity (1.x/2.x style), or message-driven bean. 
2. EJB3+ entity beans (@Entity) are POJOs and please package them as library jar. 
3. If the jar file contains valid EJBs which are annotated with EJB component level annotations (@Stateless, @Stateful, @MessageDriven, @Singleton), please check server.log to see whether the annotations were processed properly.

更新:

它还在抛出异常之前打印此行:

[#|2015-06-25T08:43:22.256-0300|WARNING|glassfish3.1.2|global|_ThreadID=126;_ThreadName=Thread-2;|Error in annotation processing: java.lang.NoClassDefFoundError: com/packageName/TestServiceInterface|#]

更新2

看起来 netbeans 能够以某种方式部署它!但是，如果我尝试直接在 glassfish 管理页面上或通过命令行(“asadmin deploy”)进行部署，则会出现异常。

我可能遗漏了一些东西，任何帮助将不胜感激。

Answer 1

由于某种原因，我的 TestSuperclass 似乎无法由远程 EJB 扩展，因此我必须删除 extends TestSuperclass。

而不是这个:

@Stateless
@Remote(TestServiceInterface.class)
public class TestService extends TestSuperclass implements TestServiceInterface<Test>, Serializable{
}

我这样声明该类:

@Stateless
@Remote(TestServiceInterface.class)
public class TestService implements TestServiceInterface<Test>, Serializable{
}

现在它不再抛出异常了。
