Answer 1

I read lot in order to make it run but, nothing could help,

(Somebody said it is the known bug in eclipse)

So I just,

2. added all the required classes folders and jars to the Libraries folder
3. added bin folder containing all required .dll to PATH environmental variable

and yay... :) It worked...
