General
The G24 KJAVA product runs one of the following two types of MIDlets:
User MIDlet (UM)
The UM is the customer's MIDlet which controls the G24 to its needs. The UM is the core
concept within the G24 Java module. It lets the customers to run their own code on the G24's
CPU. UM is expected to run "forever"
Note: MIDlet-Name attribute (in JAD file) must be "UserMIDlet" (case sensitive) and is
verified during MIDlet installation (Any other name will cause the MIDlet to be rejected).
Default MIDlet (DM)
The DM is a MIDlet provided by the manufacturer. It is a backup MIDlet which enables basic
control in case UM has failed or is absent (e.g. out of the factory). It also enables the customers to
broadcast a command for a fresh UM download to all of their newly scattered units.
