We use slf4j and logback for logging in our java ee web application. 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 <http://logback.qos.ch/manual/loggingSeparation.html>. The logback-<context-name>.xml is placed in WEB-INF\classes directory. After this change, logging for hibernate and http-client libraries is defaulting to debug mode and hence there is lot of logging being done. The root logger has INFO log level and there are no specific loggers defined for hibernate & http-client libraries. If I revert this change i.e. remove the jndi entry in web.xml and rename the configuration file to logback.xml, only INFO logs are logged as expected. Any suggestions on what could be the issue? Thanks, Amit.
