Hi,

You might have the mail and activation classes in 2 different jars in the application classpath. There is a chance that both j2ee.jar and (mail.jar & activation.jar). The versions are different - it was using the javax.mail classes from j2ee.jar. So please do a search in all your jars for the file MailcapCommandMap.class and identify the wrong version.

Hope this helps...

Thanks,
Shriniwas
