The problem is that you need a mail server that can send the mail. You
are supposed to have found one, and configured the context init param
called smtpServer with the address of that mail server. You haven't
done so, and therefore smtpServer remains null, which generates the
error above when you try to add it to a list of properties to send mail.
The solution is to add this parameter to web.xml (or some web container
config file, such as Tomcat's server.xml).

I put:
<Resource name="mail/Session" auth="Container"
type="javax.mail.Session" mail.smtp.host="mail.iskon.hr" />
inside
</Host>

as I find on Net and restart Tomcat. Then I noticed that tomcat log gives
me:
