# server

[Ahmed Riyadh]

Does anyone know why I'm getting this error message? it shows right after commenting on the implementation ch.qos.logback:logback-classic
I'm using Kotlin JVM but I want to not use the logback classic and use the Kotlin/native simple logger

[Rob Elliot]

Did you visit the "See xxx for further details." link in the error? It works, and explains what you need to do...

Something is bringing in SLF4J transitively, and trying to log to it. SLF4J is just a facade, If something tries to log to it and no implementation is present it spits that error out to standard err.

I don't know what you mean by "Kotlin/native simple logger".

[Ahmed Riyadh]

I don't know what you mean by "Kotlin/native simple logger". Perhaps

https://ktor.io/docs/logging.html#native

[Ahmed Riyadh]

Remove the word simple, there is another built-in logger that doesn't require anything related to jvm

[Ahmed Riyadh]

Doesn't require the library I mentioned above or the logbacl.xml

[Ahmed Riyadh]

The docs doesn't cover on how to not use the default logger

[Rob Elliot]

Are you sure you're running the native server? That run dialogue looks like you are running a JVM.

[Ahmed Riyadh]

Of kotlin/nvm

[Ahmed Riyadh]

No, I'm running Kotlin/JVM and I just want to disable the default logger to use the Kotlin/Native, it ƒunction is already avaliable on Kotlin/JVM, just need to disable the logger or Kotlin/JVM

> Ktor provides different means of logging your application depending on the used platform:
>
> On JVM, Ktor uses SLF4J API as a facade for various logging frameworks (for example, Logback or Log4j) and allows you to log application events. To enable logging, you need to add dependencies for the desired framework and provide configuration specific for this framework.
>
> You can also install and configure the CallLogging plugin to log client requests.
>
> For the Native server, Ktor provides a logger that prints everything to the standard output.

That's the same link I sent

[Rob Elliot]

Why do you think it is incorrect when it says "On JVM, Ktor uses SLF4J API"

[Ahmed Riyadh]

And I want to disable it

[Ahmed Riyadh]

I'm just asking if there is a way to

[Rob Elliot]

If you don't want any logs at all, add implementation("org.slf4j:slf4j-nop:1.7.36") to your dependencies.

[Rob Elliot]

If you want logging to std err without configuration (or std out if you set a system property org.slf4j.simpleLogger.logFile=System.out), add implementation("org.slf4j:slf4j-simple:1.7.36").

[Ahmed Riyadh]

ok, thanks

[andylamax]

its ironic that disabling (removing) a feature requires adding a dependency

[Rob Elliot]

Rather than disabling a feature think of it as replacing the implementation of an interface the code depends on.
