Interface EJBMetaData
- public interface EJBMetaData
The EJBMetaData interface allows a client to obtain the enterprise Bean's meta-data information. EJBMetaData接口客户端获取企业Bean的元数据信息。
The meta-data is intended for development tools used for building applications that use deployed enterprise Beans, and for clients using a scripting language to access the enterprise Bean. 设计元数据是为了让开发工具创建部属企业Bean的应用程序,让客户端使用脚本语言访问企业Bean。
Note that the EJBMetaData is not a remote interface. The class that implements this interface (this class is typically generated by container tools) must be serializable, and must be a valid RMI/IDL value type. 注意EJBMetaData不是一个远程接口。实现该接口的类(该类一般由容器工具生成) 必须可序列化,且必须是一个有效的RMI/IDL值类型。
