Actually my web application is in asp. I want some visual display of
graphs in java applet and want the user to be able to see his/her
graphs in different ways like Bar chart, Line chart , Pie chart etc.
I could not find any such facality in ASP. Now I have made an applet
that can fetch live data from database  . But I want my applet to be
secure so that user can fetch his/her data but at the same time could
not be able to perfome some malicious operations on my database.
