Hi,
all LWUIT components are lightweight and allow you to override paint
(com.sun.lwuit.Graphics) in order to paint anything anywhere so there
is no technical need for Canvas.
Since most MIDP related graphics API's are supported by LWUIT
graphics (and some more) it should be pretty easy to port your Canvas
to LWUIT. This would be the correct and portable way to achieve
something of this type.
If you have a binary canvas which you can't modify you can follow the
instructions in this thread, but this is not recommended:

Hi shai,
Thanks for reply i had tried that given example but not able to run it.
I found some issue:
1) I am not able to invoke paint() define in Canvaswraper class.
2) Is there any getGraphics() is present in Lwuit which return j2me Graphics instance, i haven't found it.I am using latest release API (LWUIT_20080714) .
Thanks
rajesh

Hi rojunwal,
1) If the paint method was kept protected and you can't derive from
the class then you are out of luck.
2) Please read the entire thread which discusses the package
protected nature of the method... Your code must be in the same package.
I suggest you talk with the supplier of the classes, generally its
very easy to build a map component in LWUIT.

Hi Rajesh,
I don't quite understand the question.
