Hey!
This requirement suggests the use of an applet. It interacts with the user and
the easiest way to implement it is with an applet doing a JDBC connection to your
DB. Doing that much interactivity requires alot of work using servlets. Plus a
servlet design, if you you cookies or Java script makes your software non 100%
Java and therefore less portable. If portability is not a concern, then search
this list's archive. Many many posts contain designs for doing what you require.
We use a combination of applets and servlets in a corporate intranet environment.
When it makes sense to use a servlet, we do.
Lalith, "using applets it's very easy but what I need is using servlets" why.
Just curious.
