The Little Engine That Could?

Now that Google has added Java support to the App Engine, I decided to finally give it a try. I decided to go the Eclipse plug-in route since I already use Eclipse, but the plug-in didn't seem to include the development server (as the docs lead me to believe), so I couldn't test the sample application locally. Rather than try and figure out what was wrong, I downloaded the standalone App Engine SDK and installed that as well. I got a bunch of errors when I started the development server because it requires Java 6 and I'm running Mac OS X 10.4, which doesn't have an official Java 6 SDK (remind me again why I thought switching to Mac was a great idea for Java development?). I tried the ancient pre-release Java 6 JDK that Apple put out a few years ago but it failed with a bunch of weird XML parser errors, so I tried SoyLatte JDK 6 1.0.3 and that finally worked. I logged into App Engine to register my account (which can only be done via SMS) and entered my mobile #, but I have I yet to receive my activation code text message so I'm stuck for the time being. From what I've read, others appear to have had more luck with it, so as always YMMV.
