Sorry but I don't know JSP and I can't provide you with an example of  
how to do it using that language specifically (most users here won't  
be able to, since this is not a JSP mailing list). In the previous  
message Kevin just provided a link for a great example in Perl.

As I said, the programmer needs to make a *system call* (every  
programmer should know what this is), invoking "rrdtool fetch" with  
the appropriate parameters.

The output from that command will have the data you need, then just  
display it the way you prefer.

Again, please refer to the documentation in http://rrdtool.org/
