Neeraj's Tech Scribbles

Simply put, this is my very own google index into the technology world. I intend to post my learnings in various technologies as and when I learn 'em.
Beyond this, there shouldn't be a single line here which is not useful to someone else :).

Java alpha-numeric security image generator (CAPTCHA) libraries

I've been asked this question more than once. Are there any Java based libraries out there that can generate those skew alpha-numeric images to block bots from entering certain parts of my web-site?

Yes, of course, there are! Look at:
