java - jPOS 无法从服务器接收 ISOMsg

Question

我通过this一步步设置jPOS JAR服务器.我通过以下代码创建服务器:

public class jPOSServer implements ISORequestListener {

    public static void main(String[] args) {
        try {
            Logger logger = new Logger();
            logger.addListener(new SimpleLogListener(System.out));

            XMLChannel serverChannel = new XMLChannel("localhost", 9000, new XMLPackager());
            ((LogSource) serverChannel).setLogger(logger, "server-channel-logger");

            ISOServer isoServer = new ISOServer(9000, serverChannel, null);
            isoServer.setLogger(logger, "server-logger");
            isoServer.addISORequestListener(new jPOSServer());

            new Thread(isoServer).start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public boolean process(ISOSource isoSource, ISOMsg isoMsg) {
        ISOMsg m = isoMsg;
        try {
            m.setMTI("0830");
            m.set(11, "000002");
            m.set(41, "00000002");
            isoSource.send(m);
            return true;
        } catch (ISOException e) {
            e.printStackTrace();
            return false;
        } catch (IOException e) {
            e.printStackTrace();
            return false;
        }
    }
}

登录 JAR 服务器在这里:

我通过telnet localhost 8000将数据发送到端口8000上的JAR服务器，JAR服务器将数据传递到端口9000上的服务器。JAR服务器接收数据和日志数据，将数据发送到服务器，服务器接收数据。但是 Read timeout 发生了错误。我调试了 JAR 文件，发现错误是在 BaseChannel.java:777 上的 b = this.streamReceive(); 处触发的。我怎样才能解决这个问题？谢谢。

Answer 1

b = this.streamReceive() 中的错误是什么意思？您的问题似乎是这样的:

        <result>
         <fail>
           [MISCONFIGURED_ENDPOINT] o.j.t.p.QueryHost.prepare:60 'DESTINATION' not present in Context                    
         </fail>
       </result>

这意味着 QueryHost 参与者不知道将消息发送到哪里，这就是您没有响应的原因，您需要将目标 mux 添加到上下文中，显然在“DESTINATION”键下。我不知道你是如何创建上下文的，如果它使用的是 IncomingListener 你就错过了这个条目

<property name="ctx.DESTINATION" value="jPOS-AUTORESPONDER" /> 

改变 jPOS-AUTORESPONDER 无论你的多路复用器名称是什么。
