【问题描述】：
我正在尝试使用 Liberty Application Server 执行 JNDI 名称搜索。但是，它给我带来了依赖注入问题。附加的是我的代码
我收到以下错误：
[ERROR ] SRVE0319E: For the [com.airline.controllers.FlightDetails]
servlet, com.airline.controllers.FlightDetails servlet class was
found, but a resource injection failure has occurred. CWNEN0030E: The
server was unable to obtain an object instance for the
java:comp/env/com.airline.controllers.FlightDetails/flightService
reference.
The exception message was: CWNEN1003E: The server was unable to find
the Web1/FlightService binding with the

System.out.println(flightService);
}
catch(Exception ex){
ex.printStackTrace();
}
if(flightService !=null){
out.println(flightService.getAirplaneModel());
out.println(flightService.getFrom());
out.println(flightService.getTo());
}
}
--------************server.xml*********----------------
