Question

在从JBos4.3迁移到5.1时,出现了以下问题:

第一个例外是在部署期间,没有执行EJB LocalObject:

Caused by: java.lang.IllegalStateException: EJB 3.0 Core Specification Violation (4.6.9): The session beanÔÇÖs local interface interface com.company.project.BeanLocal must extend the javax.ejb.EJBLocalO

OK, then I implemented the interfaces, but JBoss isn t satisfied and is now complaining: the bean must not implement EJBLocalObject! Any Ideas?

EDIT:我应该提到,信使是EJB3.0,也提供了EJB 2.1客户的观点。

声明认为:

@TransactionManagement(TransactionManagementType.CONTAINER)
@TransactionAttribute(TransactionAttributeType.REQUIRED)
@Stateless
@RemoteHome(R2PRegistrationHome.class)
@RemoteHomeBinding(jndiBinding = JNDINames.BEAN_FOR_EJB_2_1_EJBHOME)
@LocalHome(R2PRegistrationLocalHome.class)
@LocalHomeBinding(jndiBinding = JNDINames.BEAN_FOR_EJB_2_1_LOCALHOME)
public class Bean implements BeanLocal, BeanRemote {
}

Answer 1

班级不应实施部件接口。将执行条款从Bean类别删除,改变Bean Local界面,以扩大EJB LocalObject,并改变BeanRemote接口以扩大EJBObject。

Answer 2

为了让你的生活更加简单,我建议不要把一个表象变成一个EJB3和EJB2。创建一个单独的EJB2灯,代表EJB3。

This also makes it easier to simply delete the EJB2 bean as soon as you don t have to support that anymore.

此外,您可以删除@transactionManagement(TransactionManagementType.CONTAINER)和。这些都是缺省,不需要,因为EJB3强调公约过于组合。你重新开始方案的做法似乎与EJB3的精神背道而驰。如果你是唯一的策划者,这不会成为一个问题,但是在EJB3培训的其他人可能不会对此做出反应。



下面的内容应当足够:

@Stateless
public class Bean implements BeanLocal, BeanRemote {
}

Answer 3

根据第二套中程,你似乎正在使用与当地和偏远地区相同的接口。如果你分别建立单独的远程和地方接口,就应当罚款。
