运行Stateless,Remote EJB时候报javax.naming.NameNotFoundException: FirstEjbBean not bound解决办法

运行Stateless,Remote EJB时候报javax.naming.NameNotFoundException: FirstEjbBean not bound
1.环境：
myeclipse6.0+jboss-4.2.2.GA
2.jboss可以正常启动和关闭
3.我已经把%JBOSS_HOME%\client\*Jar加到客户端类中。
遇到问题：

at com.mxf.ejb.FirstEjbClient.main(FirstEjbClient.java:22)

4.我的代码如下：
--接口
package com.mxf.ejb;
public interface FirstEjb {
public String sayHello(String str);
}

--接口实现Bean
package com.mxf.ejb;
import javax.ejb.Remote;
import javax.ejb.Stateless;
@Remote
@Stateless
public class FirstEjbBean implements FirstEjb {
public String sayHello(String str) {
return "您好！"+str;
}
}

--客户端
package com.mxf.ejb;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class FirstEjbClient {
public static void main(String[] args) {
try {
InitialContext itx = new InitialContext();
FirstEjb firstEjb = (FirstEjb)itx.lookup("FirstEjbBean/remote"); ---执行到这里报错
String str=firstEjb.sayHello("remain");
System.out.println(str);
} catch (NamingException e) {
e.printStackTrace();
}
}
}



------解决方案--------------------
用main函数应该不可以吧，做成web应用，放到jboss里就好了。
------解决方案--------------------
@Remote 
@Stateless 
这里要明确指定。
@Remote(FirstEjb.class)
@Stateless(FirstEjb.class)
