Commons CLI here too; I don't remember there being a lot of choices the last time I looked, but that was some time ago. And I probably didn't spend a huge amount of time looking.
We tried Commons CLI on one project a few years ago, but at the time it seemed like a very odd, cumbersome API. Maybe that's changed, I don't know. For the few command line args I've had to parse, I just manually walk the array and hand-code it. For apps with a handful of args, this seems preferable to sucking in yet another "mini framework".
We've used JOpt Simple in a couple of small projects. I liked how easy it was to get things like help out of it's data structure, and how clear the construction of the options were in the code.
I haven't had an opportunity yet to use it, but I have been keeping my eye on Groovy's CLIBuilder, which seems dead simple. Here is an example of it being used, http://docs.codehaus.org/display/GROOVY/WrappingGroovyScript

Apache commons CLI here...

CLI-parser (annotations based):

It is < 10k and does a great, terse job.
You should read this: http://javathink.blogspot.com/2008/04/why-does-parsing-arguments-in-java-suck.html.

Eric:
Try out cli-parser.. it is tiny, has no dependencies and makes it much easier than your solution even for just a few arguments.

Something I needed that Apache Commons CLI didn't do:
myprogram --foo xxx --foo yyy
would somehow get me a List<String> with xxx and yyy in it.
I've now settled on args4j
I found CLIs a bit too complex for my use on small prototype console applications.
I have created a project and uploaded the source using google-code.
I am a student of Java so I am sure a number of enhancements to this class are needed; fyi, have a look at:

btw: thanks to Bob and you for Guice; it is a real useful tool; simple and useful.

I second args4j, it's insanely simple to use.
Yes, I do.
