It is not even working in LWUITDemo.jar also....is there any solution for this or is there anyway to disable virtual keyboard in midlet

The issue is specific to the current version of the LWUIT designer and will be fixed in an upcoming update.

The compilation issue you are experiencing is due to the usage of the UI project rather than using the appropriate port (e.g. the MIDP/UI project).
