I'm back (For those that have seen the previous messages). I'm now trying to
incorporate the jcl-slf4j bridge. Maven pulls sfl4j-1.5.0 transitively for
logback 0.9.9. So I assume I should be using jcl-over-slf4j version 1.5.0.
however there is no such version in the maven repository. The documentation
says to do this:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>1.6.2</version>
</dependency>
But if I do that I get the following:
SEVERE: Exception sending context initialized event to listener instance of
class org.springframework.web.context.ContextLoaderListener
java.lang.NoSuchMethodError:
org.slf4j.impl.StaticLoggerBinder.getSingleton()Lorg/slf4j/impl/StaticLoggerBinder;
at org.slf4j.LoggerFactory.bind(LoggerFactory.java:128)
at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:108)
Thoughts?
TIA,
- Ole

Hi,
I think the solution is to just include the logback-0.9.9 dependency
version, like this:
<!--
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<type>jar</type>
<version>1.6.2</version>
</dependency>
-->
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<type>jar</type>
<version>0.9.9</version>
</dependency>
Now I get the following transitive dependencies:
[INFO] +- ch.qos.logback:logback-classic:jar:0.9.9:compile
[INFO] | +- ch.qos.logback:logback-core:jar:0.9.9:compile
[INFO] | \- org.slf4j:slf4j-api:jar:1.5.0:compile
This seems contradictory to what the "Baby Steps" in the user manual has
though:
http://logback.qos.ch/manual/introduction.html
The baby steps indicate that we should be running with slf4j 1.6.2.
Thoughts?
Cheers,

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,
