Not sure, but my first WAG would be that you might have multiple copies / versions of the mail and activation jars. This can run up against some of the webapp server security rules.

Try removing them from the WEB-INF/lib directory and seeing if these removes the conflict.

Hi,

I've got the following exception when JForum sends an email (when a moderated message is validated for example) :

I don't have multiple copies or versions of the activation and mail jars in WEB-INF/lib.

But you might have copies in other directories in the class path... e.g. there might be one in the JVM you're using, or in the shared or common directories of your application engine.

For various security reasons, if a class is loaded at a "higher level", it can't dynamically create a class from a "lower level" jar (this would let application people inject code into the system level and do intentional or unintentional "bad things")

So, what may be happening is that a root class from the activation package is being created at a higher level first (maybe by another webapp or the system), then when internally it tries to dynamically load/create a class, the class is being found at a lower level. This is then denied by the security mechanism and generally gets reported as a "class not found" error.

Thank you for your explanation !

So I tried to remove the 2 jars in WEB-INF/lib but I've got the same exception
