I picked up Jython Essentials on my way home last night, more or less on a whim. I don't actually use Jython, but a juxtaposition of my language of choice, my favourite technical publisher, and my workaday language was impossible to resist.
Its a good book, and I learned a lot about Jython. It's even cooler than I thought. You can subclass Java classes in Jython, or vise versa. A Java class subclassed in Jython can then be re-subclassed in Java again. It's just all too cool to be true!
Type conversions between the two languages is pretty much automatic, though you can get fine control if you want it. You can embed Jython in a Java app if it needs scripting. You can compile a Jython app into a single Java class or jar, either a small one requiring the
jython.jar to run, or a big standalone one. And the interactive prompt is a brilliant way to explore the behavior of Java existing classes, and to smoke test your own. It's a one stop shop for all your Java scripting needs.
It also got me thinking again about why I prefer Python to Java so much. The things which irritate me the most are these:

Having said all that, Java has its pluses - interfaces are really cool, and JavaDoc is a wonderful tool.Posted to Python by Simon Brunning at May 02, 2002 03:59 PM
