Hi Andras (and everybody else),
This means that while generating the html page I have to hard code the
values of radio buttons(00001,xxxxxx etc) in the servlet, while as my
category code is a field of category master table. In case my master
changes, i will have to change my servlets aslo.
This is not a feasible solution, I believe.
That is where basically the problem is.
I am looking for solution to this.
thanks,
manoj
