I have to choose the second option(rrdtool).
see, what i have done:
i already created rrd file and its graphs.
so, the only thing which is remains is what, i want to fetch the data 
from rrd file and show it numerically in a JSP table .
i need a sample or example to see how, programmers have do this job in a 
certain JSP page.

best Regards
Amir Azhdari
