OK,
I found 2 missing jars from the maven dependencies that appeared in the
drools project,
and apparantly are mandatory:
jxl.jar
xstream.jar
both were available via the maven2 repo.

I'm still having problem unfortunately.. :(
i get a strange error that i didn't got before turning to maven:
when running:
*kbuilder.add(ResourceFactory.newClassPathResource("src/main/rules/sample.drl"),
ResourceType.DRL);*
this errors occurs:

... 3 more
i see a difference between the .classpth and .project files in both
projects (Drools project vs Maven Project).
could this be the reason?
