如何从远程客户端访问实体bean？
我在服务器中有这个：
class Person{...}
并且
@Stateless
public class HelloServiceBean implements HelloServiceLocal, HelloServiceRemote {
public Person getPerson(String name) {
return new Person(name);
}
}
我在我的客户端（在某些不同的 JVM 中）中有这个：
public static void main(String[] a) throws Exception{
String name = "java2s";
HelloServiceRemote service = null;
service = (HelloServiceRemote)new InitialContext().lookup("HelloServiceBean/remote");
Person p = service.getPerson(name));
}
例如，当我需要从我的 EJB 调用 getPerson() 方法（该方法返回 Person 类型的对象）时，我如何客户会明白 Person 是一个类吗？
我是否必须在客户端中重新编写 Person 类（以及 HelloServiceRemote 类），以便它可以理解什么是 Person ？或者我是否必须将 Ejb 项目包含到我的客户端项目中？
i have this in the server:
class Person{...}
and
@Stateless
public class HelloServiceBean implements HelloServiceLocal, HelloServiceRemote {
public Person getPerson(String name) {
return new Person(name);
}
}
And i have this in my client (in some different JVM):
public static void main(String[] a) throws Exception{
String name = "java2s";
HelloServiceRemote service = null;
service = (HelloServiceRemote)new InitialContext().lookup("HelloServiceBean/remote");
Person p = service.getPerson(name));
}
When i need to call, for example, getPerson() method from my EJB, which return an object of type of Person, how my client is going to understand that Person is a class ?
Do i have to re-write the Person class another time in my client (and also the HelloServiceRemote class), so it can understand what is a Person ? Or do i have to include the Ejb project into my client project ?

您必须在客户端包含包含接口、实体和实体的 EJB 项目的 jar。使用的其他实用程序类。
但在客户端公开 Entity Bean 并不可取，您可以在 http://www.ibm.com/developerworks/websphere/library/bestpractices/ejbs_access_entity_bean.html
You have to include jar of EJB project at client side containing Interfaces, Entities & other utility classes used.
But exposing Entity Beans at client side is not preferable, you can get more information regarding this at http://www.ibm.com/developerworks/websphere/library/bestpractices/ejbs_access_entity_bean.html
