 Thanks for your input, Igor! Looks nice, but I'd also like to have that as a
 rendered image, rather than plain text (security risk?).

Well, tanks ;-)
I was hoping to find some ready-to-be-used library/components that 
already does that ...

Take a look at

http://wicket.apache.org/docs/1.4/org/apache/wicket/extensions/markup/html/captcha/CaptchaImageResource.html

You might need to override some of it, or make your own customized version
to get the text and look you want.  Looks like a good starting point at
least.

I know it was a dry spirited answer.. But have a look at jcaptcha or
simplecaptcha.. Both are built around servlets as far as I can see,
but they might offer a question / image engine also (so you can use it
directly with wicket)..

Math captcha with Wicket?

2010-05-03 Thread Thomas Götz 
Did anyone ever integrate some kind of math capture with Wicket (please 
solve the following simple equation ...)? How would I do this, someone 
got a code pointer for me?
