log4j v2 binding?
Hello Ralph,
Could you please explain how bindings are done in log4j v2? I see that
there are multiple artifacts produced such as log4j2-core.jar,
log4j2-api.jar, log4j12-api.jar, log4j2-jcl.jar and slf4j-impl.jar. Are
these supposed to be present on the class path simultaneously or at most
one at a time?
For example, assume I wish to use the slf4j API with log4jv2 as the
backend. What do I do?
Many thanks in advance,

Got it. It's LogManager in org.apache.logging.log4j. BTW, sorry to reply
to my own messages.
I guess the idea is to forward calls to log4j to log4jv2 using
log4j12-api.jar. For JCL, log4j2-jcl.jar contains an Log implementation
plus LogFactory. For SLF4J, slf4j-impl.jar contains a binding. It all
makes sense.

The main API is log4j2-api. The binding to the implementation happens in
LogManager.
log4j12-api is the support for applications written to Log4j 1.2, slfjj-impl
is the binding to allow applications using SLF4J's API to work with the
Log4j 2.0 implementation, and log4j2-jcl provides the support for
applications written to commons logging. These bindings will all use both
the Log4j 2 api and core components.

A pointer to the class responsible for "binding" would be sufficient to
get me going.
