Question about velocity: using VelocityView

[Karla Borecky]

Thank you, Scott - I have those things open as I write this and I'll study
them. I'm new to java stuff so I have a bit of a steep learning curve.

So, to reiterate! What I want to do is 1) have our users run an application
that will allow them to select an image and phrase to display on the shib
login page; the application will store their choices in cookies; and then
2) be able to read those cookie values into variables that I can use in the
login.vm. I don't want to use javascript directly inside the view to read
the cookies because that is readable by anyone going to the page, and then
the phishing jerks would have the name of the cookies, defeating the
purpose of foiling their annoying practices. (Someone in our department got
a phishing email that had grabbed our shib login images and all the rest of
it, and it annoyed the hell out of me.)

The only other thing I could think to do would be to store something
generic like a number in the cookie, which would then refer to values
stored in a local database, but then I have to deal with accessing db
tables inside a view, which seems even more complicated.

What is the developer version of the phrase 'my eyes are too big for my
stomach'?
