javax.naming.CommunicationException:Receive超时[根异常为java.net.SocketTimeoutException:Receive超时]

我是新来的，正在学习EJB3.0

MyFirstEJBAP

@Stateless
@RemoteBinding(jndiBinding="bean1")
public class MyFirstEjb implements MyFirstEjbRemote {


    private Logger log = Logger.getLogger(MyFirstEjb.class);

    public MyFirstEjb() {
        // TODO Auto-generated constructor stub
    }

    @Override
    public void doSomething() {
        log.info("do something has been called");
    }

    @Override
    public String getDescription() {
        return "get description has returned some value";
    }
}

EjbTestClient.java

public class EjbTestClient {

    public static void main(String[] args) throws NamingException  {
        InitialContext context = new InitialContext();
        System.out.println("context lookup finished");

        MyFirstEjbRemote proxy  = (MyFirstEjbRemote)(context.lookup("bean1"));
        System.out.println(proxy.getClass().toString());
        System.out.println(proxy.getDescription());
        proxy.doSomething();
    }

}

jndi.properties

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming.client
java.naming.factory.provider.url=localhost:1099

我认为防火墙可能是问题所在，并禁用了它，但问题仍然存在

context lookup finished

在控制台上打印，几秒钟后我收到一个错误：-
