I have a web page having a typical form which contains following fields - name,
address and contact information. I have to add the details entered in the fields
to the table in the database. Which Java technology should I use and How? Also
How do you I check for duplicates in the table. i.e. how do i check whether what
the user has entered and what i intend to add to the table and the records in
the table are the same or not.
