当我尝试运行 JAX-RS 时，我收到错误消息，我怎样才能让它工作？PlayerManagementLocal 是 ejb PlayerManagement 的 @Local 工作正常。
错误信息
com.sun.jersey.api.container.ContainerException: An instance of EJB class rest.JSONService could not be looked up using simple form name or the fully-qualified form name.Ensure that the EJB/JAX-RS component implements at most one interface

return "ahojky";
}
@GET

public String getting(@PathParam("param") String msg) {
System.out.println("");
if(playerManagement.checkPlayer(msg)){
return "yes";
}
return "no";
}
}
这是代码，无法弄清楚如何让它工作 - 例如....在数据库中找到一些东西并将其与 POST/GET 服务中的字符串进行比较。
