Note: any errors in this post are mine, not Ben's.Many of you might think that the idea of porting Perl to the Java Virtual Machine (JVM) is silly.

I have just uploaded Class::CGI 0.03 to the CPAN. It should be there soon. Basically, it lets you treat form data as a collection of objects. It's very easy to use and extend. You can now set up a profile file which is a centralized spot for your handler declarations (these tell which CGI parameters get mapped to which objects).
