The problem was caused by their use of org.apache.log4j.net.SMTPAppender =
(actually they were using com.tgerm.log4j.appender.GmailSMTPAppender, =
which extends SMTPAppender).

log4j was being loaded from the Geronimo root classloader (log4j is =
packaged in our lib). The root classloader does not include the javamail =
spec api classes. And thus we end up with a confusing =
NoClassDefFoundError.

Their app included log4j. So, adding:

                <dep:hidden-classes>
                        <dep:filter>org.apache.log4j</dep:filter>
                </dep:hidden-classes>

to their deployment plan fixed the problem. If the app didn't include =
log4j, you could add a dependency for the log4j jar in their deployment =
plan=85

You should probably also review docs on application specific logging -- =
https://cwiki.apache.org/GMOxDOC22/configuring-application-specific-loggin=
g-with-log4j.html
