Creating custom 404 error pages

What should you take into account when you create custom 404 (Not Found) error pages?
That's the question I just asked myself and did some "Google Research".
I got lots of results how you have to configure Apache or IIS, but that's not what I'm interested in.

Here are some results which cover what I want to know:
* Useful "Page not found" error pages
* Implementing Sensible 404 Pages With Apache

Java-based Argument Parsers

I just was in the need of an java-based argument parser.

That's what I found:
* JSAP (pretty active; seems to be the most advanced incl. usage generation, support for datatypes and Unix-style cascaded configuration files with default values)
* jcmdline (not as active as JSAP; aims for standardized commandline options, allows more sophisticated validations, displays usage and error messages)
* JArgs (not much active, very simplistic and easy to use)

It's hard to say which one is the best, since all suite different needs.
If you wonder, for my task I chose JSAP, but I'll keep an eye on all of them.

Update 2004-04-23:
Phil Wilson pointed me to one more:
* Apache Jakarta Commons CLI (seems to be similar in functionality and usage like JSAP)

Groovy : a powerful dynamic for the Java Platform

Groovy really seems to be a promising new agile dynamic language for the JVM.
You don't know how simple programming can be if you don't have a look at the syntax of Groovy.
