slf4j Problem

[Kuhnen]

Hello everybody.

Hello akka people, can you guys help me with that?

log4j:WARN No appenders could be found for logger
(akka.event.slf4j.Slf4jEventHandler).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig
for more info.

I want to use the slf4j logger but i keep getting this warning, and it
does not work.

I'm puting a actor.jar on the deploy directory. The Akka version is
1.1.2.
The defaulListener is working fine.


My akka.conf file:


event-handlers = ["akka.event.EventHandler$DefaultListener",
"akka.event.slf4j.Slf4jEventHandler"]
event-handler-level = "INFO"

My dependencies:


resolvers += "Typesafe Repository" at "http://repo.typesafe.com/
typesafe/releases"

{
val version = "1.1.2"
libraryDependencies ++= Seq("se.scalablesolutions.akka" % "akka-
actor" % version,
"se.scalablesolutions.akka" % "akka-remote" % version,
"se.scalablesolutions.akka" % "akka-slf4j" % version)
}


libraryDependencies += "ch.qos.logback" % "logback-classic" % "0.9.28"
% "runtime"


scala version = 2.9.1.

What am i missing?
Thanks a lot

Somewhere log4j is used. Might be in your application or dependent libraries. You probably wan't to setup a log4j-to-sl4fj bridge.

Replacing the log4j.jar file with log4j-over-slf4j.jar.

Read all about it (and more) here: http://www.slf4j.org/legacy.html

Let us know if log4j is used in any of Akka's core dependencies.

Did you follow the link? You need a log4j.properties or log4j.xml at the root of the classpath.

Hope that helps,
François

Thanks for the quick response.
François is right, if a put a log4j.xml file it does work, but the
logback.xml that comes with the akka 1.2 version does not work, and I
wonder why?
The log4f: WARN did not appear if I start the 1.1.3 version akka
microkernel.
Would that be a bug?

Just to keep things clear.
I downloaded the type-safe stack (akka version 1.2) and did not change
any file, besides the akka.conf to add the slf4j event handler.
It works fine if I put a log4j.xml file on the config directory, but
it does not read the logback.xml file (I guess)

By the way, Patrick, thanks for the advice, I will read that today.
