Hi Rajendra!
A jsp page is compiled to a servlet (to the purists: yes I know this is
not a must be the result nevertheless will behave as if)
so you have access to all the servlet stuff inside and so you can
access databases and whatever you like.
Here a (very!) short overview:
<% your-code-here %> whill be put in the service-method where
you have access to the vairbales request and response.
<%! your-methods-and-servlet-attributes-here %>
will but your code on the class level so you can define methods
and attributes.
<%= your-java-expression-here %> will allow you to insert the output
of java expressions into your html templeta text.

> The way I have implemented it currently is - having JavaScript arrays

>1 - Completely do away with the servlet. Have a jsp file which will have all

>SQL to save the data.
> The advantage here would be that I wouldn't need to do a lot of coding

>I can elaborate more on my question if it is not clear.
