Hi Manoj,
It seems that you didn't understand what 'Craig McClanahan' has said. You
don't need to hard code the radio button values as you're querying the
values from category_master table. You need to construct the html page from
servlet A with the data (category_code) queried from category_master. Even
if you change the master table, servlet A will take that value and construct
the html dynamically. This way you don't need to change your servlets for
changes that you make in category_master table.
Hope you would understand.
Regards,
Kumar
