Subject Re: java.lang.ClassNotFoundException: org.apache.log4j.LogManager on startup of new deployed .war
Date Tue, 13 Nov 2012 18:02:14 GMT
Are you including a Log4j implementation in your app?  Geronimo provides log4j interfaces through
pax-logging and the result is that by default you can't use the log4j configuration system
in your app.

IIRC you can either use geronimo's log4j (remove the log4j from your app and configure app-speciifc
logging as described in the docs  https://cwiki.apache.org/GMOxDOC30/configuring-application-specific-logging-with-log4j.html
) or configure your app to not import the log4j classes.  Unfortunately I don't recall the
exact way to exclude the log4j classes, I think you put them in a <hidden-classes> element
in the environment in your plan.

hope this helps
