Examples of org.apache.vinci.transport.ErrorFrame

org.apache.vinci.transport.ErrorFrame
This is a special VinciFrame that simplifies returning error or exceptional conditions. If a service returns an error frame, then the client's request method will in response throw an exception with the provided error_message. Returning an error frame from VinciServable.eval() has the same effect as throwing a ServiceException.


    VinciFrame out = new VinciFrame();


    String name = in.fgetString("SERVICE");
    if (strip(name) == null)
      return new ErrorFrame("No service name specified");


    String host = strip(in.fgetString("HOST"));
    String realhost = strip(in.fgetString("IP"));
    if (strip(realhost) == null && strip(host) != null) {
      try {
        // Try to resolve the IP if possible
        realhost = (InetAddress.getByName(host)).getHostAddress();
      } catch (Exception e) {
        // realhost = null;


        // return error message
        return new ErrorFrame("Could not resolve IP address for service " + name);
      }
    }


    String instance = in.fgetString("INSTANCE");
    int inst = -1;
