求教：初学EJB遇到问题

public interface HelloWorldRemote {



	String name();

}

public interface HelloWorldLocal extends HelloWorldRemote{}

@Stateless

@Remote(HelloWorldRemote.class)

@Local(HelloWorldLocal.class)

public class HelloWorld implements HelloWorldRemote, HelloWorldLocal {

	@Override

	public String name() {

		return "getName";

	}

}

public static void main(String[] args) throws NamingException {

		Properties props = new Properties();

		props.setProperty(Context.INITIAL_CONTEXT_FACTORY,

				"org.jnp.interfaces.NamingContextFactory");

		props.setProperty(Context.PROVIDER_URL, "127.0.0.1:1099");

		props.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming");

		InitialContext ctx = new InitialContext(props);

		HelloWorldRemote remote = (HelloWorldRemote) ctx.lookup("HelloWorld/remote");

		System.out.println(remote.name());

	}

用的是JBOSS7发布的


运行JBOSS的standalone.bat


异常信息：
