I don't seem to be ever getting around to doing this and now a Java developer with a Nokia has asked me for it, so here is the full source code to the phone EXIFy lightmeter.
Well, I say "full"; it's very simple! If you have seen Java before and have the J2ME SDK you should be able to do something with it.
I will try to do a more informative post on it soon. You will obviously need Java installed and also the J2ME 3.0 SDK.
Quickly, though: /_support contains the Javascript files I ported the EXIF reader from (see this post), /src/akme/mobile/util contains maths routines missing from the mobile edition (check the source for URLs and credits), /src/expinfo contains the hastily hacked together and very horrible code for the MIDlet itself, /src/rext/graphics contains a routine for generating thumbnails that seems to exist across many blog and forum posts, and /src/rext/simpleexif is the main codebase, containing the EXIF reader port and the code for moving around EV values.
I stopped developing the code as soon as it worked for the first time, so it is a fairly parlous state :o)
If you have found this post and are not a developer but just want to try the app, the Flickr group has more useful info.
