Topic: Failed to initialize FHIR Restful server
Rajan Kumar (Oct 11 2020 at 12:47):
Hi, I am new to FHIR APIs. I have decent Java experience and am putting my hands on FHIR APIs for the first time.
I am trying a small prototype where in I tried to use FHIR Java APIs (https://hapifhir.io/) along with Spring Boot. I have FHIR APIs included as my project's Maven dependencies and my Spring Boot is starting without any issues.
My RestfulServer implementation goes as below
//Initialize
@Override
protected void initialize()throws ServletException{
//create a context for the appropriate version
setFhirContext(FhirContext.forR5());
registerProvider(new PatientResourceProvider());
}
However, when I try to access http://localhost:8080/metata getting below exception. Any help is greatly appreciated.

You might raise this on the #hapi stream, which is focused on the Java reference implementation

Great, thank you!
