you need to specity both these paramters in the jad:

MIDxlet-API: VSCL-1.0.1
Midlet-Install-Notify: http://a.valid.url.for.gx20.security-model

both must be present else if fails

you can also change the scale factor of the gx20 (which by default scales to
120x130):
MIDxlet-Application-Resolution: w,h
