Hello! After starting startdog-server on my Ubuntu Server i get the following error: ERROR 2023-06-22T12:20:40,381+0000 [main] com.complexible.stardog.protocols.http.server.StardogHttpServiceLoader:createService(132): Unable to create an instance of HttpService class com.complexible.stardog.protocols.http.cache.server.CacheHttpService, missing compatible constructor.
I really can't understand it and don't know where to start checking.
Regards,
Roland
Greetings Roland,
What version of Ubuntu? What version of Java? And how are you starting the server?
Matthew
Hello Matthew,
i am using Ubuntu 22.04.1 LTS, Java openjdk 11.0.19 2023-04-18 and starting the server using the command "./stardog-admin server start" in my stardog-9.0.1/bin folder.
EDIT: i found the following message in the logs: ERROR 2023-06-22T14:13:57,345+0000 [main] com.complexible.stardog.protocols.http.server.StardogHttpServiceLoader:createService>
Roland,
This is odd. Would you be able to send the stardog.log file via a direct message to me?
Matthew
Certainly, but I really can't find the option to send a private message…
EDIT: i unlocked the private message function. 
I had the same error, also I use Ubuntu LTS 22.04 and Stardog 9.0.1, in addition I tried with java 11, java 17 and java 20, but still having the same issue:
ERROR 2023-06-22T12:20:40,381+0000 [main] com.complexible.stardog.protocols.http.server.StardogHttpServiceLoader:createService(132): Unable to create an instance of HttpService class com.complexible.stardog.protocols.http.cache.server.CacheHttpService, missing compatible constructor.
Please if you find any solution share it with us
Roland,
I have the stardog.log file, thank you. Sadly no big clues jumping out.
From where did you download the program? I want to make sure I am using the exact build as you.
Matthew
Hi,
i followed exactly this tutorial: Install from Zip | Stardog Documentation Latest.
Sadly, the download works for me.
Would you upload your license file to my via private message? Still trying to isolate the problem source.
Matthew
Roland,
I have duplicated your issue. It is related to the license file. It will be tomorrow (Friday) before I can consult with colleagues on a fix.
Matthew
Roland,
Your license has 3 features intentionally disabled: geospatial, LDAP, and caching. Some how the intentional disabling of caching has started causing this error message. We will fix that message in a subsequent release.
You should be able to safely ignore that error message and use Stardog for your investigations.
Good luck,
Matthew
This error message is limited to users that have a "community license". The error message is incorrect. A correction to the code did not make the 9.1.0 release, but will be present in a subsequent release.
Again, apologies for the confusion.
