Are you kidding at us? Please see the MIDP specification or at least another MIDlet as example.
The MIDlet can not be java.lang.Class. If you created no new package in your JAR I guess it is Born4Pure. The path should be relative or absolute only to a HTTP server and not locally. The size is to large for a Nokia 6610. It has a limitation of around 63 kB.
If the MIDlet suite contains only one MIDlet it is recommend to use the same icon for the suite (MIDlet-Icon property) and the MIDlet itself (MIDlet-n property) because devices take sometimes this and sometime the other icon. Make sure your MANIFEST includes the following, too.
