I do have four servlets for each screen.
1. DB Maintenance servlet which select, update, insert and delete from
database-any thing to do with database.
2. Kind of Interface servlet between HTML controller, DB Servlet and get data
from any where else and do the proxying(maintain the lists for next previous
etc.)
3. HTML Controller- this decodes all the get and post request to screen and call
all the necessay actions and save the result to the sesssion and forward to the
dispaly servlet.
4. Display servlet - get the data from session and display.
