Question

我有以下错误

 Exception in thread "main" javax.naming.NameNotFoundException: CounterBean not bound

尝试从Application Server外部的客户端应用程序访问部署在JBoss5上的EJB JAR CounterBean.jar。

从Jboss日志看，它看起来没有全局JNDI名称？这个可以吗？我做错了什么？

JBoss日志：

13:50:39,669 INFO  [JBossASKernel] Created KernelDeployment for: Counter.jar

客户端代码是：

public static void main(String[] args) throws NamingException, InterruptedException {
    InitialContext ctx = new InitialContext();
    Counter s = (Counter)ctx.lookup("CounterBean/remote");
    for(int i = 0; i < 100; i++ ) {
        s.printCount(i);
        Thread.sleep(1000);
    }
}

这是我在JBoss 5.x上部署带有远程接口的简单无状态会话Bean（SLSB）时得到的结果：

当我查看您提供的跟踪时，我看不到任何与远程接口相关的内容（您需要进行远程调用），因此没有JNDI名称。所以问题是：您的SLSB是否正确定义并实现了远程接口？

就我而言，我的bean定义如下：

@Stateless
public class EchoBean implements Echo {
    ...
}

远程界面如下：

@Remote
public interface Echo {
    String echo(final String in);
}

你有类似的东西吗？

JBoss EJB Bean没有绑定
