[logback-user] LoggerContext instance - how many are created?

[Ceki Gulcu]

Since logback will initialized only once, when the first web-app is loaded into 
memory. Thereafter, all logging will go to the same file. You must not share the 
  logback jar by placing them on the web-container's lib directory. You should 
instead have each web-app carry its own copy of logback jars in WEB-INF./ib.

Alternatively, you can use the JNDI repository selectors. However, wait for 
logback 0.9.12 and SLF4J 1.5.6 before delving into that.
