[logback-user] Logback defaulting to debug mode for some third party libraries

[David Roussel]

Run it in a debugger, set a breakpoint in the hibernate class in question and step through the JNDI lookup code.

Logger instance creation calls ContextJNDISelector.getLoggerContext() method. This method does a JNDI lookup but does not find the entry.

Recently in order to move these libraries to a common location in the glassfish app server (to glassfish\lib directory specifically) we made a couple of configuration changes. We made changes in the web.xml file to add JNDI entries and renamed the logback.xml to logback-<context-name>.xml as specified in here. The logback-<context-name>.xml is placed in WEB-INF\classes directory.
