The problem occurs because the Orbeon webapp sets a system property
named "log4j.configuration" in the org.orbeon.oxf.util.LoggerFactory.
Because this value is deliberately set to a bogus value, any webapps
in the same JVM (same tomcat in this case) that start after Orbeon,
will fail using the regular configuration discovery mechanisms of Log4j.
I am not sure if the conditions for this design decision are still
present. They might be. My opinion is that any webapp that sets a
system property better have an extremely good reason for doing so,
given that system properties are shared across the entire JVM, not
just webapp.
Our solution was to programmatically configure Log4j by loading the
properties manually and then call the PropertiesConfigurator in
Log4j. Another option would be to modify the source in Orbeon, or to
petition the Orbeon development team to fix this issue.
