<i>UbiMail - Ubiquitous e-mail system</i>
</body></html>
The core of the application is
main.jsp
. If this is the first invocation of this
JSP in the session, it starts a new mail session, connects to the server and
opens the default message folder. Otherwise it recovers the mail objects
stored in the session attributes. This page builds a table and for each
message in the folder adds a row containing the subject, the sender and the
date of the message. Each message has a number that is a link to the JSP that
shows the contents; the URL has an additional
?index
#
n
where
n
is the
number of the message. This is the standard way of passing parameters. To
make reading a long list of messages easier the rows alternate a light blue and
a pink background.
