EJB代码：

public interface HelloBussiness {
String hello();
}

@Stateless
@Remote(HelloBussiness.class)
public class HelloBussinessImpl implements HelloBussiness{
public String hello() {
return "So Damned hard, Hello World, EJB3.0";
}
}

客户端代码：

Hashtable pro = new Hashtable();
pro.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
pro.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
pro.put(Context.PROVIDER_URL, "localhost:4447");
try {
Context ctx = new InitialContext( pro );
String lookupStr = "ejb:/HelloWorld//HelloBussinessImpl!rmt.HelloBussiness" ;
Object rmtHomeObj = ctx.lookup(lookupStr);
if( rmtHomeObj != null ) {
HelloBussiness remoteObj = ( HelloBussiness )javax.rmi.PortableRemoteObject.narrow(rmtHomeObj, HelloBussiness.class);
remoteObj.hello();

}

}catch( Exception ex ) {
ex.printStackTrace();
}

EJB成功部署，部署信息如下：

java:global/HelloWorld/HelloBussinessImpl!rmt.HelloBussiness
java:app/HelloWorld/HelloBussinessImpl!rmt.HelloBussiness
java:module/HelloBussinessImpl!rmt.HelloBussiness
java:jboss/exported/HelloWorld/HelloBussinessImpl!rmt.HelloBussiness
java:global/HelloWorld/HelloBussinessImpl
java:app/HelloWorld/HelloBussinessImpl
java:module/HelloBussinessImpl

运行后报异常：
