JBOSS 下调用EJB3.0出错

import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;

public class MyTest {
public static void main(String[] args) {
// System.setProperty("java.security.policy","client.policy");
// if(System.getSecurityManager()==null)
// System.setSecurityManager(new RMISecurityManager());
   
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "localhost:1099");
env.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
      try{ Context ctx=new InitialContext(env);
           Object ref=ctx.lookup("HaiEJB");
           HaiHome home=(HaiHome)PortableRemoteObject.narrow(ref,HaiHome.class);
           HaiClient user=home.create();
           System.out.println(user.sayHai());
        }catch(Exception e) {
        System.out.println(e.getMessage());
        }

   }


}

环境:
Win XP SP3
JDK 1.6.11
Jboss4.0.3sp1
去掉注释的代码就：
