1. you should use:
<dependency>
<groupId>org.apache.geronimo.configs</groupId>
<artifactId>javamail</artifactId>
<type>car</type>
</dependency>
to minimize the chances of ClassCastException due to loading javamail
in the wrong classloader
2. this still won't work unless log4j is using the
public static Class<?> forName(String name, boolean initialize,
ClassLoader loader)
method with the ThreadContextClassLoader. Can you construct the
appender yourself in your servlet init method, where you _can_ access
javamail classes via the above dependency, and register it with log4j
in code?

Hi All!
I have very strange problem.
In my geronimo-web.xml I wrote:
<dependency>
<groupId>repository.org.apache.geronimo.javamail</
groupId>
<artifactId>geronimo-javamail_1.4_mail</artifactId>
<version>1.2</version>
<type>jar</type>
</dependency>
but when SMTPAppender for Log4j is being loaded I get:
java.lang.NoClassDefFoundError: javax/mail/Multipart
java.lang.Class.getDeclaredConstructors0(Native Method)
java.lang.Class.privateGetDeclaredConstructors(Class.java:2389)

org.xh.log4jtest.Test.init(Test.java:21)
I've looked the repository/org/apache/geronimo/javamail/geronimo-
javamail_1.4_mail/1.2/geronimo-javamail_1.4_mail-1.2.jar file
and I can see that there is javax/mail/Multipart.class file.
Is geronimo not loading my dependency or is it something else?
best regards
