Hello dear logback commiters,
I'm trying to use SLF4j MDC in my multithread program and i'm having the
following error:
SLF4J: Failed to load class "org.slf4j.impl.StaticMDCBinder".
SLF4J: See http://www.slf4j.org/codes.html#no_static_mdc_binder for
further details.
Exception in thread "main" java.lang.NoClassDefFoundError:
org/slf4j/impl/StaticMDCBinder
at org.slf4j.MDC.<clinit>(MDC.java:70)
at fr.mipih.jms.AsynchConsumer.<init>(AsynchConsumer.java:50)
at fr.mipih.jms.AsynchConsumer.main(AsynchConsumer.java:182)
I have the following jars in the classpath :
slf4j-api-1.4.2.jar
jcl104-over-slf4j-1.4.2.jar
logback-classic-0.9.7.jar
logback-core-0.9.7.jar
I have check the content of the jars and in fact StaticMDCBinder is
nowhere to be found (should be in logback-classic-0.9.7.jar as I
understand it)
I have checked the repository at http://svn.qos.ch/repos/logback/trunk
and found that StaticMDCBinder was added in
logback-classic\src\main\java\org\slf4j\impl back somewhere in may.
I have no [easy] way to compile the new source code on my platform since
logback use maven (don't have it, don't want to install it, don't want
to learn how to use it).
Isn't it time to release a 0.9.8 or something (why not a 1.0) so that
slf4j's MDC (and other bug fixes) are available to the majority ?
TIA.
ZC.
