[slf4j-user] slf4j with logback?

[Ole Ersoy]

Hi,

I'm attempting to use slf4j with logback.  I see the following when I start tomcat:

SLF4J: slf4j-api 1.6.x (or later) is incompatible with this binding.
SLF4J: Your binding is version 1.5.5 or earlier.
SLF4J: Upgrade your binding to version 1.6.x. or 2.0.x

I'm using the following version of slf4j and logback:

[INFO] +- org.slf4j:slf4j-api:jar:1.6.2:compile
[INFO] +- ch.qos.logback:logback-classic:jar:0.9.9:compile
[INFO] |  \- ch.qos.logback:logback-core:jar:0.9.9:compile

I also get the exception pasted at the bottom of this email.  I read up on it and hibernate, ran mvn dependency:tree, and looked for other slf4j versions.  I did not find any.  I do have a dependency on JCL though.  Any ideas on what the problem could be?

TIA,
- Ole
