REST API no log output #250

Currently I am using the REST API locally by running:

\knowledge-engine\smart-connector-rest-dist\target>java -Dorg.slf4j.simpleLogger.logFile=ke.log -cp "smart-connector-rest-dist-0.1.10.jar;dependency/*" eu.interconnectproject.knowledge_engine.rest.Main 8280

Since simple logger is specified, in the command used to start the REST API, I expected there to be some logging information output. Like Knowledgebase registered, post forwarded or something similar.

However, there is no output in the cli and a ke.log file is nowhere to be found.

Hey @david.heck.iee.fraunhofer.de, the knowledge engine does print those kinds of messages and starts up with the following message:

2021-06-24 15:42:43:841 +0200 [main] INFO RestServer - Starting Knowledge Engine REST API on port 8280.

If you start it with the command you mentioned it is correct that it does not output anything at the command-line, but it is strange that there is no ke.log file. I just tried it locally, and a new ke.log file was created with the above message inside. Not sure what the problem could be, maybe no write rights?

You could try to leave out the -Dorg.slf4j.simpleLogger.logFile=ke.log part and then the logging should go to the console. The command then looks like:

\knowledge-engine\smart-connector-rest-dist\target>java -cp "smart-connector-rest-dist-0.1.10.jar;dependency/*" eu.interconnectproject.knowledge_engine.rest.Main 8280

Let me know if this changes anything.

Regards, Barry

Hey @barry.nouwt.tno.nl,

logging to the cli by leaving out the parameter works like a charm, thanks!

The ke.log is strange indeed. I have rechecked, I can not see it in Windows Explorer or linux subsystem for windows with ls -a, but I can see it in Windows Command Prompt using dir command.

Regards, David

Strange that the ke.log is partly invisible...not sure what's causes that, but I am glad you can see the log messages now!

I'll close this issue now.
