Drools runtime environment

Hi Experts,

i am very new to the Drools concept just started learning along with eclipse

i am following this site http://drools.herod.net/drools-flow/html/ch03.html

and many, i downloaded the drools jar and features into the eclipse features and plugin directory

i am getting drools perspective and new drools project but i am not getting how to set up drools runtime

first time configure workspace settings and which path i have to mention whether it is c:\eclipse\plugin

where all the jars are installed or any new location just c:\test any folder path

as i gave both the paths but are not working my java source file showing error for all the import packages of drools

so can you please tell me what is the path exactly i have to give for runtime in a very simple way.

thanks in advance.
