well, this has been eye opening. After seeing what all was involved
with Java to create CAPTCHA's, I took a look at PHP because I knew my
phpBB forum software wasn't that complicated. On the otehr hand, neither
is the CAPTCHA.
To generate good CAPTCHA's is mostly done with the GD PHP graphics
library. But then that's getting up there in complexity with the Java
graphics library, so no shortcuts there.
The Java package that looked most promising is
org.apache.myfaces.custom.captcha.util. I pulled that code into a
project. I need to go get some more supporting classes, but they're all
Apache. There is one use of HTTPServletResponse (or something close to
that), but I commented out that import and will replace whatever is
being done there with something else appropriate.
The Java code out there is understandably servlet oriented, so what
we want is a jar that ends up with a CAPTCHA PNG (or JPG or GIF) file as
output without any other interactions.
Will be interesting code to get working and post in any event.

oh yes, would be good,
not problem using java in this way, the one I can't is install, configure
and run WAS or Tomcat or Geronimo or so on for this intend..
some brave java developer here with some of this? there is any code or
library/class available?
(also I can improve my legacy of person-hating-java, btw, magnifico)
