Hi All , Can anyone point me to the source code of FHIR Validator jar . Jar works fine from command line but i want to use it in my java code to validate incoming FHIR resource.

https://github.com/hapifhir/org.hl7.fhir.core. you want the class org.hl7.fhir.validation.ValidationEngine

Grahame Grieve (Mar 05 2020 at 09:50):

or maybe org.hl7.fhir.validation.NativeHostServices

Grahame Grieve (Mar 05 2020 at 09:50):

but you would be better to use it as hosted in HAPI

"but you would be better to use it as hosted in HAPI " means which one ? Are you trying to say use Hapi Fhir Validation ?

Grahame Grieve (Mar 05 2020 at 10:16):

I think that's generally a better idea. HAPI has more run time wrapping services

I tried using Profile Validator code stated at https://hapifhir.io/hapi-fhir/docs/validation/profile_validator.html but getting issues like this :

This is the code i have executed :

FhirContext ctx = FhirContext.forR4();
FhirValidator validator = ctx.newValidator();
FhirInstanceValidator instanceValidator = new FhirInstanceValidator();
validator.registerValidatorModule(instanceValidator);

String resourceText = ResourceStringProvider.getObservationResourceInStringContained(); //get resource json
ValidationResult result2 = validator.validateWithResult(resourceText);

System.out.println(result2.isSuccessful());

Am i missing something , any pointer to working example .
