Hello,
I have written a class that extends ca.uhn.hl7v2.app.Application. I have
implemented the ProcessMessage() method. I initialize everything as follows:
LowerLayerProtocol llp = LowerLayerProtocol.makeLLP(); // The
transport protocol
PipeParser parser = new PipeParser(new
CanonicalModelClassFactory("2.6")); // The message parser
parser.setValidationContext(new NoValidation());
HL7Listener = new SimpleServer(PORT, llp, parser);
Application handler = new HL7ListenerApp();
HL7Listener.registerApplication("*", "*", handler);
HL7Listener.start();
I am working with a new system and we get bad messages that HAPI cannot
parse. For example, we get ADT-A08 messages where the MSH has no
VersionId, which causes issues :) They are meant for custom software
that is not really proper HL7. I want to ignore those, but my problem is
that HAPI bails out before i even get a chance to handle the error in my
ProcessMessage() method.
ca.uhn.hl7v2.HL7Exception: Can't find version ID - MSH has only 10 fields.
at ca.uhn.hl7v2.parser.PipeParser.getVersion(PipeParser.java:965)
at ca.uhn.hl7v2.parser.Parser.parse(Parser.java:164)
at ca.uhn.hl7v2.parser.PipeParser.parse(PipeParser.java:885)
Is there a way to catch that exception and return a custom ACK?
