JavaMail API and optional email type

[NorthStarDA]

hi,

I am trying to write a script that will take attributes and build either a text,html, or multi-part email. It's a custom tag for my App Server. I successfully got it to send a multipart message as well as text messages alone, but when i put in a conditional, it does not work.

my code is below if anyone can see what im doing wrong

thanks for any help you guys can give me

** im very new to java so if any of this is silly, don't laugh at me
