So far we supplied input values to the servlet program of web application by typing query string with request parameter in browsers adderss/URL bar as like:

http://localhost:2020/DateApp/test1?sno=209&sname=yogesh

Using query string request param to supply input values is not industry standard because that does not provide user-friendly user interface to end user. To provide GUI to end user we need to work with HTML form pages & web pages with hyerlinks.

To make these form pages & hyperlinks generating request to servlet/JSP programs we need HTML-servlet/jsp communication

diag

Form page generated request carries the form data as input data/request parameter values to server.

Hyeperlink generated request does not carry input data along with request message body.

diag:

Note: HTML program generates static web pages.
Servelt , JSP programs can generate both static, dyanamic web page.
There is no need of configuring HTML programs in web.xml file.
HTML programs are identified with their file names with extension (.html or .htm)
