If you share log4j, wouldn't it mean that if two
web-apps both use eg "com.foo.Bar", they cannot be
configured to log to different logfiles and that the
com.foo.Bar logger (with appenders) is shared between
webapps?

When you upgrade JSTL, struts, etc - all get the

means ultra stable apps which haven't been touched
in years may "magically
break".

Log4j we've found by trail and error is better to
have
a jar per webapp, as the loggers seems to
overwrite
each other, but which commonly used jars (struts,
jstl) can be shared?

I think so. But IIRC, if you have a log4j in common/lib and WEB-INF/lib - the
WEB-INF/lib will be used for that webapp. So you can place logging in a
different file for that webapp and class.
