log4j:WARN

Every time I start Servoy Developer (by the bat-file) or open a java-console of a real Servoy client I see this:

log4j:WARN No appenders could be found for logger (com.servoy.j2db.util.Debug).
log4j:WARN Please initialize the log4j system properly.

even when I start the servoy_updater.jar of Servoy4 I see this, so I see this in Servoy 3.5.8 and in Servoy 4.1.1

Can someone explain what or why this is??

This means that the “log4j…” lines in your servoy.properties files are not as they should be.
You can remove them alltogether and new default ones will be generated when starting Servoy.

You could then compare the default ones with the ones you currently have - maybe you can notice what the problem was.

I did tried that, and that is the solution!

but how can this happen? I never touched those settings.
I’m not the only one, look here viewtopic.php?f=11&t=12194

It could be that this comes from the log plugin. Maybe the log (server) tries to create a logger before Servoy inits its logger. It should not matter anyway. Could you try and see if the “error” is gone without log plugin?

I can’t reproduce right now.
I deleted the log lines in the properties file and now everything is fine!
(the log plugin is installed)
