Sony Ericsson T610 Java Woes

Friday, August 13th, 2004

I’m having a problem deploying CLDC 1.0 / MIDP 1.0 to my Sony Ericsson T610. Currently developing using early versions of J2WTK and J2SE (1.3.0), being uploaded through Bluetooth on my powerbook. Every time I upload anything but the most simple of MIDlets, I get an “Invalid Application” notifier. These apps run fine on the J2WTK MIDP-1.0 device profiles. The only app I can get to work is something that just displays StringItems. I’ve tried using simple Canvas drawing. Doesn’t work. I’ve tried using a Ticker. Doesn’t work. This is incredibly frustrating.

I’ve got the source and jarfiles for all of these. Please contact me if you’d like to help test on a T610 platform, hopefully on T-Mobile like me.

UPDATE - I fixed this problem with my MANIFEST.MF files, and it works fine now.

Datadots - an effective theft deterrent?

This article discusses the use of microscopic dots that show up under blacklight, being applied in the thousands to cars and other theft-prone items. Apparently, it has been responsible for a huge reduction in stolen cars in Australia, because it makes the stolen goods too trackable to resell. Personally, I would pay the $20-25 out of pocket if it makes me substantially more confident that my car and its parts wouldn’t be stolen. But apparently, American auto manufacturers think it’s “too expensive”. Given that they don’t lose anything when cars are stolen, it’s easy to see why.

I’ll be emailing my state farm rep and asking about this…
