回答1:

It looks like your credentials are wrong or not accepted by gmail.
You need SMTP server for sending mail. You can use one installed on your own machine

One free one is here.

Also check if you have added activation.jar

Mostly this error occurs from not having activation.jar and mail.jar on your classpath. Add them as a maven dependency or add in WEB-INF/lib and it should be fine.
