do you mean start programming using bluecove or programming in
bluecove itself??
it seems you want to program using bluecove,
add bluecove-2.0.3.jar to the project and if you use linux also add
bluecove-gpl-2.0.3.jar to the project.
bluecove APIs are standard JSR82 APIs and any tutorial for J2ME
bluetooth programming will be sufficient. and for example there is an
example bundled with Sun WTK (if you have it).
