Topic: FHIR validator ClassNotFoundException
Abigail Huang (May 21 2021 at 00:21):
Dear all,
I'm trying to validate some resource instances against DSTU2 (FHIR 1.0.2) and tried running the newest FHIR validator "validator_cli.jar" from this site (https://confluence.hl7.org/display/FHIR/Using+the+FHIR+Validator) on openJDK 16.0.1 (https://jdk.java.net/16/).
However, I keep getting this error when running the file:
Error: Could not find or load main class org.hl7.fhir.validation.ValidatorCli
Caused by: java.lang.ClassNotFoundException: org.hl7.fhir.validation.ValidatorCli
I'm new to using Java validators and would greatly appreciate any help! (Alternatively, are there any recommended DSTU2 validators I can use online?)
Thanks so much!

@Abigail Huang I am running into the same problem on both linux and MAC Big Sur. The command 'java -jar validator_cli.jar ...' seems to work find on windows for us, but not the other two. If I expand the jar and run something like 'java org.hl7.fhir.validation.ValidatorCli' from the top level of the expansion, it seems to work fine on Big Sur. I also see the same error using the openjdk:16 docker image.

Hey, I will take a look now
Mark Iantorno (May 21 2021 at 13:46):
for now you can use fhirvalidator.org
Mark Iantorno (May 21 2021 at 13:46):
while I look
Mark Iantorno (May 21 2021 at 13:47):
hrm, I can confirm it is very broken
Mark Iantorno (May 21 2021 at 13:47):
I'll look into it now. Probably something to do with the latest HAPI release.
Mark Iantorno (May 21 2021 at 15:40):
@Matt Jenks can you confirm this work on windows?
Mark Iantorno (May 21 2021 at 15:56):
Alright I've determined the issue and put in a fix
Mark Iantorno (May 21 2021 at 15:57):
but please answer my question above. It's not that I don't believe you that it runs on Windows. I just...don't...believe you.
Mark Iantorno (May 21 2021 at 15:57):
If it does, I would want to investigate further on that.
Matt Jenks (May 21 2021 at 16:00):
@Mark Iantorno Yeah fair enough. My team member @Corey Wen was the one that was running it on windows. I did not. We pulled it from this page, https://www.hl7.org/fhir/downloads.html, using this link, https://github.com/hapifhir/org.hl7.fhir.core/releases/latest/download/validator_cli.jar.
Matt Jenks (May 21 2021 at 16:01):
@Corey Wen Can you verify where and when you pulled the validator jar that was working for you on windows?
Mark Iantorno (May 21 2021 at 16:02):
Verify the version as well please.
Mark Iantorno (May 21 2021 at 16:02):
It will print when you run it.
Abigail Huang (May 21 2021 at 16:20):
thanks everyone for the help! greatly appreciated!

I downloaded the validator ~1 week ago from "https://github.com/hapifhir/org.hl7.fhir.core/releases/latest/download/validator_cli.jar", which was found at "https://www.hl7.org/fhir/downloads.html"
I believe the version is "FHIR Validation tool Version 5.3.11 (Git# 33fffe28ff6b). Built 2021-04-22T05:48:36.375Z (29 days old)"
Mark Iantorno (May 21 2021 at 17:23):
yeah, so that's not the latest that was crashing
Mark Iantorno (May 21 2021 at 17:23):
I suspect the latest will crash on all platforms
Mark Iantorno (May 21 2021 at 17:24):
There should be no reason one OS would work while the others did not
Mark Iantorno (May 21 2021 at 17:24):
The release is going right now to build the new validator
Abigail Huang (May 21 2021 at 19:11):
Just to close the loop, I tried the validator on both Mac OS and Windows and they both give the same ClassNotFoundException error. Thanks all!
Matt Jenks (May 21 2021 at 19:45):
@Abigail Huang I just pulled the updated version that @Mark Iantorno built about 2 hours ago. It is working for me in openjdk 16 docker image and locally on my mac. I pulled it from here https://github.com/hapifhir/org.hl7.fhir.core/releases/latest/download/validator_cli.jar".
Abigail Huang (May 21 2021 at 20:17):
Amazing and A HUGE THANK YOU!! It works for me now and I was able to validate my DSTU2 files without a problem.
This is a big help and most sincerely appreciated =)
(As a random FYI and now a moot point, I wasn't able to get fhirvalidator.org to work for v1.0.2. I selected v1.0.2 under Options but it keeps giving error messages when I hit validate that are consistent with R4 such as the fact that there is an
Unrecognised property '@model' or '@udi' although they exist in DSTU2 - but not R4.)
Mark Iantorno (May 21 2021 at 22:48):
okay, thanks for the feedback on that
Mark Iantorno (May 21 2021 at 22:48):
I will fix that on the website
