"StatelessBean.ejbgrpx": No JNDI name found for EJB referenced using this name: "ejb/AutoDealerHome".这是什么错误，我已经在描述

Question

No JNDI name found for EJB referenced using this name: "ejb/AutoDealerHome".

Answer 1

描述文件应该指明：
1 name for ejb ( my name is ...)
2 name for reference (the name of the ejb i want to use is ...)(i am an ejb:-) )

Answer 2

Answer 3

你是怎么写的阿jndi－name应该是AutoDealer

Answer 4

你的jndi－name在部署描述项中与LOOKUP中不一样吧。

Answer 5

public Connection initial(){
      String user="system"; // 能够登录WebLogic控制台的用户名
      String password="12345678"; //登录密码
      String dataSourceName="frameSources"; // 在WebLogic控制台配置的数据源名称      Hashtable env = new Hashtable();
      env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
      env.put(Context.PROVIDER_URL, "t3://localhost:7001");
      Connection con = null;
      try {
        Context context = new InitialContext(env);
        DataSource dataSource = (DataSource)context.lookup(dataSourceName);
        con = dataSource.getConnection(user,password);
      }catch(SQLException sqle){
        System.out.println("TestJNDI.initial [SQL]:"+sqle.getMessage());
      }catch(Exception ex){
        System.out.println("TestJNDI.initial [Ex]"+ex.getMessage());
      }
      return con;
    }

Answer 6

把
<ejb-ref-name>ejb/AutoDealerHome</ejb-ref-name>
改为
<ejb-ref-name>AutoDealerHome</ejb-ref-name>

Answer 7

已经解决了，参考资源没有jndi名，我加上了，就可以了，感谢大家的关注
