Greetings,
favorite
<https://stackoverflow.com/questions/50688192/hapi-hl7-validation-throws-exceptions#>
I am working on a Java endpoint that I intend to use for HL7 message
validation. I have a basic app running that uses a variation of the
standard HAPI HL7 validation example. If I pass in a valid message I get
the "Success" response. If I pass in a invalid message I still get a
"Success" response.
The only way I get an error response is if the HL7 is badly formatted and
the PipeParser throws an exception. In that case it gets caught in the
catch block.
What I want to see is if I pass in an invalid message that it actually gets
validated and returns all the validation errors. But I don't ever actually
see any validation. It either parses or crashes trying to parse.
What am I missing here?
HapiContext context = new DefaultHapiContext();
ValidationContext validationContext =
ValidationContextFactory.defaultValidation();
context.setValidationContext(validationContext);
try
{
context.getParserConfiguration().setUnexpectedSegmentBehaviour(UnexpectedSegmentBehaviourEnum.THROW_HL7_EXCEPTION);
Message messageValidationResults =
context.getPipeParser().parse(hl7Message);
SimpleValidationExceptionHandler handler = new
SimpleValidationExceptionHandler(context);
handler.setMinimumSeverityToCollect(Severity.INFO);
Validator<Boolean> validator = context.getMessageValidator();
if (!validator.validate(messageValidationResults, handler))
{
if (handler.getExceptions().size() == 0)
{
hl7ValidationResult = "SUCCESS - Message Validated
Successfully";
}
else
{
hl7ValidationResult = "ERROR - Found " +
handler.getExceptions().size() + " problems\n\n";
for (Exception e : handler.getExceptions())
{
hl7ValidationResult +=
(e.getClass().getSimpleName() + " - " + e.getMessage()) + "\n";
}
}
}
}
catch (Exception e)
{
hl7ValidationResult = "ERROR - " + e.getMessage();
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
e.printStackTrace(pw);
String sStackTrace = sw.toString();
hl7ValidationResult += "\n\n" + sStackTrace;
}
Thanks in advance!
