创建远程连接失败，原因是：java.lang.RuntimeException:操作失败，状态为等待

无法创建远程连接。请看控制台。 javax.naming.NamingException:未能创建远程连接[根异常为java.lang.RuntimeException:操作失败，状态为等待]

package com.as.service;

import javax.ejb.Remote;

@Remote
public interface CalculetteService {
   int add(int a, int b);
}


package com.fpt.service;
import javax.ejb.Stateless;
import org.jboss.logging.Logger;


@Stateless
public class CalculetteServiceImpl implements CalculetteService{

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

  @Override
  public int add(int a, int b) {
    return a + b;
  }
}


package com.as.test;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import com.as.service.CalculetteService;

public static void main(String[] args) {

    CalculetteService calculette = null;

    try {

        Properties properties = new Properties();
        properties.setProperty("java.naming.factory.url.pkgs",    "org.jboss.ejb.client.naming");

        properties.setProperty("jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false");


        Context context = new InitialContext(properties);


        calculette =  (CalculetteService)context.lookup("calculetteService#com.fpt.service.CalculetteService");
        System.out.println("La somme est:"+calculette.add(10, 10));
    } catch (NamingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }   
}

将服务器从JBoss AS 7.1.1更改为Wildfly 8.X。选择一种方法来调用EJB。我使用了远程命名项目（）。谢谢，这对我很有用。
