Hello,
I am trying to use JavaMail.  This is the first package not bundled with
jdk1.3 or written by myself, that I have ever tried to use...and well I can
not get it to work.  I download, unzipped, and added the packages to my
project.  If I type "import javax.mail." I get the list of classes... Yet
whenever I try to compile I get the following error:
"SendMail.java": Error #: 300 : class Session not found in class SendMail at
line 20, column 5

If I use the entire name of the class I get the followin error:
"SendMail.java": Error #: 302 : cannot access class javax.mail.Session;
class javax.mail.Session not found in stable package at line 20, column 16

Do I need to "register" this class somewhere else...?

I really am at a lose here and just need a kick start in the right
diretion...if anyone has any ideas on what I am doing wrong please let me
know...
