In the absence of formal documentation, I did a little experimentation based on a tutorial for creating JAVA MIDlets.
http://today.java.net/pub/a/today/2005/02/09/j2me1.html?page=1I am able to subscirbe to the service, but the service does not appear under my services button. However, I can assign it to a SURL button and then am able to execute it. Upon execution, it seems to run, however I get a blank service screen with the letters PK. Correct behavior is to display the date and time.
