Thanks for your reply.
So, i need to create two HTML forms, 1st for login, & 2nd for form filling. 1st Html will check the authentication . For this authentication i will create a program, which in turn checks the Username & Password from a database , say AUTHENTICATE.
If he is authorized, that will direct to another Html, asking details for inserting/updating. A servlet for this, having
JDBC connections, & business logic.
Or should i go for Separate programs for Inserting, Updating, Deleting. (In that case , there is no use for Servlet)?
Please provide some guidance.
