EJB 3存根生成 [英] EJB 3 Stub generation

问题描述

我有一个ejb-3兼容ejb，说

I have an ejb-3 compatible ejb, say

@Remote
interface Hai{
     String sayHai();
}
Stateless(name = "xxx", mappedname="yyy")
public class HaiImpl implements Hai{
    public String sayHai(){
        return "Hai";
    }
}

我需要为此EJB生成存根。但我不想使用websphere工具或maven工具。
有没有办法使用jdk生成存根？

And I need to generate stub for this EJB. but I dont want to use websphere tool or maven tool. Is there any way to generate stub using jdk?

当您创建远程客户端

 Hai hai = (Hai)ctx.lookup("yyy#com.zz.Hai");
 System.out.println(hai.sayHai());

将在weblogic或jboss中工作，但在websphere中，即使是ejb 3，您需要像这个

will work in weblogic or jboss, but in websphere, even it is ejb 3 you need to write like this

Object o = ctx.lookup("yyy");
Hai hai =    (Hai)javax.rmi.PortableRemoteObject.narrow(o,Hai.class);
System.out.println(hai.sayHai());

在这种情况下，如果存根不在客户端显示，将抛出异常，使用websphere ejb存根生成器工具生成存根的方式。但是我不想使用任何平台特定的工具。

In this case, if the stub is not presents at the client it will throw exception, there is a way to generate stub using websphere ejb stub generater tool. But I dont want to use any platform specific tools.

推荐答案

不，您必须使用WAS_HOME / bin / createEJBStubs。 Java SDK中包含的rmic命令（通常用于生成存根）不能在不扩展java.rmi.Remote的纯EJB 3远程接口上使用。

No, you must use WAS_HOME/bin/createEJBStubs. The rmic command included in the Java SDK, which would normally be used to generate stubs, cannot be used on "pure" EJB 3 remote interfaces that do not extend java.rmi.Remote.

请注意，如果您使用应用程序客户端容器（WAS_HOME / bin / launchClient）或您的客户端是另一台服务器，则不需要生成存根：容器将为您生成一个。如果您使用非托管的瘦客户端，则只需使用createEJBStub。

Note that if you use the application client container (WAS_HOME/bin/launchClient) or your "client" is another server, then you do not need to generate stubs: the container will generate one for you. You only need to use createEJBStubs if you're using an unmanaged thinclient.
