Thank you for your attention!!
Actually i'm totally new to this BPM thing, and first time using jBPM...........
I download that smple code before but thre is some error while extarcting it http://community.jboss.org/servlet/JiveServlet/downloadImage/2-594441-15219/450-267/Untitled.png
Ya i look that slides too, but lack of info there
I go through http://www.plugtree.com/plugtree-jbpm5-tutorial-1-modeling-your-basic-processes/
that was helpfull, but it wasn't enough for my requirement................
