[logback-user] Configuration initialization is too verbose

[Johan Bos]

So, the first output is because of errors!

Assuming that I used only one place for my jars, and one logback.xml file

I got 2 webapps, and the logback.xml has some reference to JNDI vars setup
in the webapps descriptors, using InsertFromJNDIAction.

So depending on the webapp loaded, the InsertFromJNDIAction will get
different value that will change behaviour of what I put inside the config
file.

This works perfectly well, when it comes to load the webapps, but the first
load by the application server, it can't resolve the JNDI variable... so it
output an error.

How can I prevent this behaviour?

Hello Gili,

In "Chapter 3 - Configuration" [1] under the section entitled
"Automatic configuration with logback-test.xml or logback.xml", it is
stated that

  If and only if there are warnings or errors during the parsing of the
  configuration file, logback will automatically print status data on the
  console.

Since logback.xml is found multiple times on your class path, logback
is issuing a warning.

HTH,
