I'm receiving this message from another server (I don't know why). We're
building an interface between our app and a HL7 server, and the first
step is just getting the HL7 messages off the wire and storing them.
The Reciever implementation is making a hard coded policy decision that
my application that's using it does not want to know about some HL7
messages.
This should be configurable, at the very least ?
I've had a rough delve through the code, and it seems because Reciever
isn't an interface, you have to replace whole chunks of other classes as
well - I think I ended up with over a half dozen cloned classes in my
package because thing's were private or package and so I couldn't extend
them easily.
Maybe it would be easier to have a setting (in HapiContext) about what
to do with them ?

Why would you send an unexpected ACK back to the server?

*AH HA*.
There's a 3 year old bug with HAPI [1] where it throws away
messages if they are unexpected replies.
I don't see a way to replace the Receiver instance in use by
SimpleServer ?

Hi,
Sorry I wasn't clear, but further down my RecivingApplication
implementation I do have that :
public Message processMessage(Message theMessage, Map<String,
Object> theMetadata) throws ReceivingApplicationException,
HL7Exception {
String encodedMessage = new
DefaultHapiContext().getPipeParser().encode(theMessage);
System.out.println("Received message:\n" + encodedMessage
+ "\n\n");
}
This never outputs.

What you probably would like to look at is the "processMessage"

Given
public class EvReceiverApplication implements
ReceivingApplication {
public boolean canProcess(Message theIn) {
System.out.println("Received message: canProcess true");
return true;
}
....
I never see this output when a message is received. So it's
like the receiver is not registered ?
I am doing
HL7Service server = context.newServer(port, useTls);
ReceivingApplication handler = new EvReceiverApplication();
server.registerApplication("*", "*", handler);
server.startAndWait();

<http://hl7api.sourceforge.net/xref/ca/uhn/hl7v2/examples/SendAndReceiveAMessage.html>
to build a simple app that should listen for all messages,
and echo them to the console (
server.registerApplication("*", "*", handler); ).
However, although I get a line from the connectionReceived
method, and none from an output I added to the
exceptionHandler, I do not get anything from my
processMessage() code.
Java 1.8 on Ubuntu Server, with the latest HAPI library. I
can confirm I am getting a message (admittedly it's MSA is
"MSA|AA|245635223|Failure") with a Wireshark packet capture.
Any ideas what could be up ?
