我正在制作POS系统，现在我正在尝试设置POS打印机爱普生tm-t20。当我尝试打开端口时，其中是打印机，我得到此错误消息：

我已经生成了jpos.xml，但我不知道将其放入项目的何处。

文件可以放在任何地方，但根目录是最好的开始位置。

/*
     If you want to place the jpos.xml file elsewhere on your local file system then uncomment the
     following line and specify the full path to jpos.xml.

     If you want to place the jpos.xml file on a webserver for access over the internet then uncomment
     the second System.setProperty line below and specify the full URL to jpos.xml.
     */

    System.setProperty( JposPropertiesConst.JPOS_POPULATOR_FILE_PROP_NAME, "jpos.xml");
    
    System.setProperty(JposPropertiesConst.JPOS_POPULATOR_FILE_URL_PROP_NAME, "http://some-where-remote.com/jpos.xml");

error try adding this

      System.setProperty("jpos.loader.serviceManagerClass", "jpos.loader.simple.SimpleServiceManager");
      System.setProperty("jpos.config.populatorFile", "jposxml.cfg");
      System.setProperty("jpos.util.tracing.TurnOnNamedTracers", "JposServiceLoader,SimpleEntryRegistry,SimpleRegPopulator,XercesRegPopulator");
      System.setProperty("jpos.util.tracing.TurnOnAllNamedTracers", "ON");
